The EE15120B DC Electronic Load /  Works @ 0.0 Volts Input & real time I/O control
 attach the electronic load block to a heat- sink and your up and running. 
used them with D to A's, A to D's, Pots, PLC's to control the current
 These Electronic Loads can be used for both Discharge & Charging Batteries & Devices
The electronic load can act as a Current Regulator for charging
