PRODUCT OVERVIEW
PPS3205t-3s programmable power supply is controlled by micro processor unit (mpu) that can easily connect communication interface RS-232 or USB to computer in order to satisfy users' demand for auto-testing and auto-control. The voltage and current are completely controlled by 12 bits d/a converter with higher resolution and accuracy. Also, the digitalization of system makes a speedy, precise and convenient input of information controlled by keyboard. The adjustment of voltage/current is made by software calibration without manual error that will increase the preciseness of the instrument. The function of over voltage protection (ovp) and over current protection (ocp) is set with software and detected with hardware to achieve protected function precisely and speedily in order to secure users from danger by using the instrument.
