Cebek R-25 module is designed to control a DC (8A) load via a low voltage control signal. It adjusts the output load using a control signal of between 0 -10 VDC. This control voltage is directly proportional to output voltage and can adjust the load in ascendant or descendent way depending on the jumper setting. The output load can be controlled via a 10KΩ potentiometer if required. There is a LED indicator to give visual indication of output.
