Constant Current Power Supply - 13.8V 8A

A simple constant current power supply that outputs 13.8VDC and 8A. It comes in a robust metal enclosure (IP68 rated) with a 100,000 hour service life. It features Over-voltage, Over-current, Short Circuit, and Over-temperature safety features. This can be used for charging Lead Acid batteries similar to the one we sell but requires good knowledge of how to do so. It also works for powering LED lighting-type devices.

The charger accepts 8-36V DC inputs via 14 AWG wires (The Red and Black ones) and outputs 13.8VDC and a constant 8A for current via the 16AWG wires (Yellow and Black).

Constant Current Power Supply - 13.8V 8A Product Help and Resources

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

4 Electrical Prototyping

Skill Level: Experienced - You will need to consult a datasheet for calculations to determine a components output format, linearity, and do a little math to get what you need. You will be using a datasheet or schematic beyond basic pinouts.
