GW Instek PSU 400-3.8 DC Power Supply

GWInstek’s PSU 400-3.8 is a 1520W 1U height 400V/3.8A DC programmable supply designed to meet high voltage test and measurement requirements.

The PSU range of high voltage supplies such as this one have settings for Constant Current priority or Constant Voltage priority. When using CC or CV mode, users can adjust slew rate for output voltage or current based upon test requirements. There are two kinds of slew rate settings: high speed priority and slew rate priority.  High speed priority sets slew rate at the maximum speed to reach CC or CV mode. Slew rate priority allows users to set slew rate for CC or CV mode in order to control rise or fall slew rate. Slew rate priority mode is ideal for motor tests by adjusting the rise time of output voltage to protect DUT from being damaged by inrush current occurred at turn-on.

The new PSU high voltage series is ideal for testing DC/DC converters and servomotors, or integrated into component test systems such as ageing test equipment for capacitors and diodes, 600V DC bias applications, semiconductor production equipment, automotive electronics, ECU requirements for V8 engine or V12 engine, etc. 

The Over-voltage (OVP) and Over-current (OCP) protection prevent the DUT damage. Both OVP and OCP levels can be selected the range of 10% to 110%, with the default level set at 110% of the power supply’s rated voltage / current. The PSU-Series provides USB Host / Device , LAN, RS-232 with RS-485 and Analog Control Interfaces as standard. A LabView driver is also available for rear-panel external control of Power On/ Off and external monitoring of the power output voltage and current.
