The DHP family provides models ranging in output power from 5 kW to 20 kW in a single chassis. Programmable output voltages range from 5V to 400 VDC, delivering up to 3,000 amperes. This family has two operational modes, constant-voltage and constant-current. The DHP family uses control technology that allows 9 auto sequence steps, each step can be up to 99,999 seconds in duration. Combining all the steps allows a maximum auto-step program 27.7 hours long. Various voltages, currents and durations can be programmed for each step. This family has standard analog and a variety of combinations of IEEE-488.2, RS 232 and/or isolated analog input control interface options.
