Twintex Lab System Rack Mount 3kW 3A RS232 RS485 Remote Control Programmable 1000V DC Power Supply

Twintex Lab System Rack Mount 3kW 3A RS232 RS485 Remote Control Programmable 1000V DC Power Supply

PWD1000-3 is a high voltage programmable DC power supply, rated output 0 to 1000 volt 3A, full range adjustable.

PWD1000-3 has automatic crossover between Constant Voltage (CV) mode and Constant Current (CC) mode.

In CV mode, the output voltage is adjustable, and the output current is automatic.

In CC mode, the output current is adjustable, and the output voltage is automatic.


The output voltage and output current are adustable through front panel controls and through remote control by computer via RS232 & RS485 intertace. Over Voltage Protection (OVP), Over Current Protection (OCP) and Over Temperature Protection (OTP) protects the power supply from unexpected conditions. For more complicated applications, the power supply is available with many optional functions: remote sensing, remote ON/OFF control, timer switch, square waveform output, PV curve output, etc.
