Programmable Dc Power Supply

The Programmable DC Power Supply offers a wide range of models and voltage options, including 300V, 600V, and 1000V series, with power ratings from 3kW up to 15kW per unit. It supports high current output up to 60A and allows parallel operation to achieve power levels up to 150kW. The supply features high precision voltage and current measurement, programmable voltage and current slope changes, and customizable sequences for output control.

Additional functions include remote voltage compensation, DC-ON output signal, and comprehensive protection mechanisms such as over-voltage, over-current, over-heat, and fan failure alarms. The device boasts a full-color LCD display and digital keyboard for ease of use, a no-load fast discharge design to enhance safety, and interfaces including standard RS-232 and optional GPIB for remote communication. Its design also effectively prevents current reversal, making it a reliable and versatile solution for demanding power supply applications.
