These are accessories for LED Lighting in RVs and Boats we have found to be useful: voltage-regulator and 12-volt power supplies.

Maybe they will fit your needs as well.


VR12 regulater

Purchase from BLI
VR12-3A Inline Voltage Regulator: This in-line 12-volt, 3amp regulator keeps the 12-volt line voltage to LED appliances in an operating range that will not damage the LEDs, even while working with resistive and electronic dimmers. It comes with built-in polarity, thermal, and short circuit protection. It has double-stick adhesive tape on the back for mounting on a heat-sink surface.

This device acts as a voltage clamp, limiting the output to a maximum of 12.1 volts. If the input voltage falls below 12, the output will follow it down. If the input voltage goes above 12, the device will limit the output to 12 volts and waste the excess voltage as heat. Therefore, the VR12-3A needs a good heat sink if you use it in higher voltage configurations. With a sufficient heat sink, the device can operate with an input voltage up to 28 volts DC. 



SENSA On/Off/Dimmer
                            control

Purchase from BLI

SENSA On/Off/Dimmer Control: The SENSA power controls allow an LED circuit to be turned On or Off or to be controlled by a PWM signal that allows for dimming the LED lights.

Control of the SENSA is accomplished through a capacitive proximity sensor. This sensor is on the case of the switch or can optionally be located on an antenna at some remote location from the power control.

The SENSA control handles up to 120 watts of power. The Pulse Width Modulation circuit operates between 100% and 20% utilization at a 1 KHz clock rate.

Note that the PWM circuit may not work well with certain kinds of power regulation circuits that attempt to smooth variations in the DC voltage. 


AC/DC inline 12v power supply


Purchase from BLI

PS1, 25W to 150W Power Supplies:
The PS1 series of industrial regulated 12-volt power supplies are designed to be connected directly to the 120VAC wiring behind the wall. Each acts as a power center for a cluster of 12-volt appliances. They are recommended if you want to install LED lighting in domestic housing.

The PS1-xx power supplies are all UL approved.

Care should be taken to install appropriate 12-volt wiring between the power supply and the 12-volt appliances. Speaker wire is often sufficient, but watch the AWG gauge of the wire you are using.

The higher the AWG gauge number of the wire, the smaller it is and the fewer amps it can carry without overheating. The table below shows the output of each power supply and the maximum AWG gauge number wire to use if ALL the current is put through that wire, and assuming that wire run is less than 10 feet. Go to a smaller gauge number when in doubt just to be sure.

The table also shows the physical sizes of the power supplies.
