This module is a versatile and fully adjustable high current voltage regulator with output current limiting. It is meant to be mounted directly on a specific 12V server power supply. Two different models are supported:
Both are available in used condition for little money via platforms like ebay – sometimes for less than 20€. Other models may also work if they provide a compatible pinout. For more details, please refer to the kSupply user manual. Alternatively, the module can also be connected to any 12V power supply (like for example a desktop computer’s ATX power supply) by attaching cables to its screw terminals.
The module has been designed to rapidly charge the kCap ultracapacitor module for high speed welding, but it can also be used for many other applications that require a stabilized voltage at high amperage. For example, build a high current laboratory power supply from it by attaching external potentiometers for voltage and current.
The ability of the module to operate either in constant-voltage or in constant-current modes also allows to use it as a charger for high capacity Lithium batteries. Please note, that in such a case additional protection circuitry is mandatory to safely operate these batteries, e.g. a BMS.
With a small hardware change, the module can also operate in two quadrants and is able to transfer negative output current back to its input terminals.
An optional heatsink kit is also available.
This article does not include output cables, as their length and termination is highly application specifc. If you plan to use this module to power a kCap ultracapacitor module, then you need to make a suitable cable, or you can purchase a preassembled cable kit.
