Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to electrical power supplies, and more particularly to low voltage electrical power supplies. Broadly, embodiments of the present invention provide a modular upgradeable low voltage power supply. The invention allows users to modularly configure their power supply system so that it is tailored to changing power demands as power requirements expand or decrease.

2. Description of the Related Art

The following detailed description is of the best currently contemplated modes of carrying out exemplary embodiments of the invention. The description is not to be taken in a limiting sense but is made merely for the purpose of illustrating the general principles of the invention.

Most end-users or contractors would like to increase the power of their current power supply to be able to add more electrical loads. However, with existing power supplies, the user can not increase the power output of the power supply. In these cases, the user has to purchase a new power supply unit and redo the installation to increase electrical capacity.

In the event of a power supply failure, the end-user or contractor has to scrap the previous power supply unit and replace it with a new one having a capacity to meet the electrical demands.

Separate power supply units occupy a lot of space, especially if a project gets expanded during installation. As can be seen, there is a need for improved low voltage power supply that is modular in construction to permit expansion and repair of the power supply.

There are various patents that have issued that have involved modular power supplies or modular transformers, but these have not involved the use of low voltage power supplies. These include, for example:

Korean Pat. Publication No. 10-2010-0063676, to General Electric Company, of New York, United States America, Shenecteddy, One River Rowd (72), entitled “Distribution System”, discloses a submarine power distribution system which is stacked and interconnected to meet site expansion requirements and electrical load topology. A plurality of modular transformer building blocks are included on each of the power supply side and the subsea load side. The power distribution system includes a system DC transmission link/bus, wherein the system DC link includes a plurality of submarine load modules configured to transmit HVDC or MVDC power. The topology of the stacked modular substation on the seabed side of the subsea power distribution system is symmetric with the topology of the stacked modular substation on the land/top side of the subsea distribution system.

U.S. Pat. No. 7,759,575 B2, entitled “Expandable Power Distribution Unit”, issued to Commscope Technologies LLC, discloses a power distribution unit that includes a first power box including a first chamber having a first termination zone, wherein a first wire set from a supply conduit is configured to be terminated at the first termination zone. The power distribution unit also includes a second power box ganged together with the first power box. The second power box has a second chamber open to the first chamber, and the second chamber has a second termination zone. A second wire set from at least one of the supply conduits and the first termination zone is configured to be terminated at the second termination zone.

Neither of the above examples, nor other prior art discloses low voltage modular power supplies.

As will be disclosed below, the user-friendly, modular design of the present invention helps the user configure their power supply to existing and emerging electrical power requirements.

Additionally, a dynamic voltage switching system is disclosed to enhance the efficiency and flexibility of outdoor lighting installations.

In another broad aspect, the present invention is a modular power supply system comprising an enclosure and a casing assembly contained within the enclosure. The casing assembly includes a plurality of slots. The casing assembly is configured to accept a plurality of transformer modules configured to slide into the slots. Each of the transformer modules is of a type having a transformer module housing, and a transformer element positioned within the transformer module housing.

In a preferred embodiment the casing assembly comprises a frame assembly, a plurality of spaced rails, a plurality of terminal blocks and at least one printed circuit board. The frame assembly comprises a plurality of panel elements. The plurality of spaced rails defines the plurality of slots, the spaced rails being supported by the panel elements. The plurality of terminal blocks is supported by the panel elements. At least one printed circuit board is connected to the panel elements.

In an embodiment the at least one printed circuit board comprises a controller printed circuit board. The controller printed circuit board comprises a plurality of PCB components and a PCB mounted transformer.

The plurality of PCB components includes an MCU (Microcontroller Unit), a relay, a wireless communication technology module (e.g., Bluetooth or Wi-Fi Module), at least two output current transformers (CT's), an input current transformer (CT) and an alarm.

The MCU is configured to execute machine-readable program code for causing, when executed, the computer to perform selected steps. The relay is operatively connected to the MCU, for shutting off the power to the transformer modules. The wireless communication technology module (e.g., Bluetooth or Wi-Fi Module) is operatively connected to the MCU for communicating with a smartphone app. At least two output current transformers (CT's) are operatively connected to the MCU for measuring the output current of the modular power supply system. The input current transformer (CT) is operatively connected to the MCU to measure the input current of the modular power supply system. The alarm is connected to the MCU for making a buzzing or beeping noise for certain conditions.

The transformer module is configured to be accepted within a modular power supply system of a type having an enclosure, and a casing assembly contained within the enclosure. The casing assembly includes a plurality of slots.

Thus, the system includes a plurality of transformer modules that can be easily added or removed from a power supply system to increase or decrease the power capacity of the unit. In case one module fails, the end user can remove and easily insert a new transformer module without buying and installing a whole unit. Thus, the user is able to repair the power supply unit by easily replacing the failed transformer module, instead of scrapping the whole power supply unit.

To increase the power capacity, the user adds one or more transformer modules. To decrease the power capacity, the user can remove one or more transformer modules. The transformer module may be readily transferred to another location where additional power output may be required.

The modular low voltage power supply unit saves substantial space for contractors, distributers, etc. as there is no need to carry multiple of power supply units with redundant parts due to their being packaged in a separate power supply. Instead, the user can carry small modules for any expansions during installations.

In this aspect, the dynamic voltage switching system for a casing assembly of an outdoor lighting modular power supply, includes at least one relay operationally connected to a microcontroller unit (MCU) of the casing assembly of an outdoor lighting modular power supply, said relay being configured to facilitate the switching of the output voltage of the modular power supply. Means are included for communicating voltage level commands from a switch mechanism to the at least one relay to regulate the output voltage of the dynamic voltage switching system.

As will be disclosed in detail below, the invention optimizes the power consumption of outdoor lighting systems by dynamically adjusting the voltage levels supplied to individual zones based on real-time demands.

As in the previous embodiments this modular power supply is particularly adapted for outdoor lighting use. It preferably includes three CT's 70, 72, 74, that are operationally connected to an MCU 76. The MCU is configured to measure the output current in each zone of the modular supply system.

In this preferred alternate embodiment, one set of two relays 78, 80 are operationally connected to the MCU 76 of the casing assembly 68 of an outdoor lighting modular power supply. Each set of relays is configured to facilitate the switching of the output voltage of the modular power supply. In this preferred embodiment shown in FIG. 13, three sets of two relays 78,80 are utilized.

The wireless communication technology module (designated 46 in FIG. 5) provides means for communicating voltage level commands from a switch mechanism to the sets 78, 80 of two relays to regulate the output voltage of the dynamic voltage switching system.

Thus, at the core of the casing assembly 68 of the modular power supply system of the FIG. 13 embodiment are the output current transformers (CTs), a set of at least two devices. These CTs are strategically placed to measure the output current in each zone of the modular power supply system. This real-time current data provides essential information about the lighting load in each zone.

The MCU serves as the central processing unit, orchestrating the entire system's operation. It receives input from the CTs regarding the current consumption in various zones. The MCU also connects with other crucial components, such as the wireless communication module and the relays.

By actively modifying the voltage levels, the system can adapt to varying lighting demands and optimize energy consumption. The MCU evaluates the current load and decides whether to increase or decrease the voltage supplied to specific zones.

The wireless communication technology module establishes a seamless wireless connection between the dynamic voltage switching system and a mobile application. It enables remote control, monitoring, and adjustment of the lighting zones. The wireless connection is established using modern communication protocols, ensuring secure and efficient data transmission

In a preferred embodiment, a mobile application is installed on a user's mobile device, enabling intuitive interaction with the dynamic voltage switching system. Users can remotely access the system, view real-time data on power consumption, and control the voltage levels of individual zones. The application's user-friendly interface provides an easy means to adjust lighting preferences, making it an essential tool for managing outdoor lighting environments.

In another preferred embodiment, the system incorporates a toggle switch within the mobile application interface or a mechanical switch for on-site control. Users can effortlessly select and set desired output voltage levels for different zones. These voltage preferences are communicated to the MCU for implementation.

As discussed above, the dynamic voltage switching system includes the memory storage unit within the module. This unit stores voltage level data received from the mobile application, ensuring that user preferences are retained even in the absence of an active connection.

The dedicated power supply unit ensures that the dynamic voltage switching module and the wireless communication technology module receive a stable power source. This unit guarantees the consistent operation of the entire system.

The dynamic voltage switching system for modular outdoor lighting power supply offers several significant advantages, including:

Effortless Voltage Switching: The dynamic voltage switching system offers users the convenience of remotely controlling and transitioning between various output voltage levels using the mobile application, eliminating the need for physical adjustments to connections in the terminal block.
