The paper describes development and testing of PC based 12 channel, 0- 400V power supply. The supply consists of 12 independent power module, 12 channel DAC card and 0 - 400 V high voltage power supply. The Power module consists of 2 MOSFETs in pseudo push-pull arrangements for sourcing as well as sinking current. A program has been developed in Turbo C/C++ to generate ramp output of 0-5 V for 12 channel DAC add on card in PC. This ramp output is given as input to power module card, which generate high voltage accordingly. The programmable power supply has been tested for piezo-actuator with capacitive load of 20 nF.
