This is a modular system which can be configured by the user to use for DC constant current loads up to 200 Amps at voltages up to 60 V. There are 2 modules of 10 Amp & 20 Amp each. Each one has a Potentiometer & an ammeter to set the load current. All of them can be cascaded to achieve the required load OR all can work independent. There is digital input to each load which will put ON or OFF the load. A PLC can be used ( which we can provide ) to program a ON OFF cycle & a cycle count to ensure that the load current is ON & OFF for a given time & programmed number of cycles.
