The GW Instek PSU 40-38 power supply with 1U height is highly praised by various markets and it is widely utilized by system integrators. The PSU 40-38 provides 1520W, 40V/38A. The PSU4038 is suitable for electric components manufacturers to verify withstanding current tests of 100A and above. Such tests include micro-resistor, relay, shunt resistors etc. The high voltage models of the PSU-series, not only can fully satisfy the extensive voltage demands of 1U power supply market but also provides system integrators with more flexible system integration.

The flexible arrangement of the PSU-series can reduce investment on test equipment facing different voltage and current test regulations. The PSU 40-38 is a single power output DC programmable power supply, which outputs 1520W. The PSU 40-38 provides maximum 2 units in series connection (models under 300V) to achieve maximum 600V or 4 units in parallel connection to obtain maximum 800A and the maximum output power of 6.24 kilowatts.

The PSU 40-38 allows settings for CC priority or CV priority. Under 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 because it can protect DUT from being damaged by inrush current occurred at turn-on. Comparing with other 1U power supplies available in the market, the PSU 40-38 supports a most complete array of interfaces, including USB, LAN, RS-232, RS-485, analog control interface, GPIB (option), isolated analog interface (voltage control), and isolated analog interface (current control).

Via the multi-drop mode, the PSU 40-38 will not need any switch/hub and GPIB cable for remote control and slave unit augmentation when using LAN, USB or GPIB. This feature can help users save costs on equipment.

The PSU 40-38 is ideal for the primary input of DC/DC converter and servo motor production application. The PSU 40-38 is often integrated into component test systems such as aging test equipment for capacitors; 600V DC bias applications; aging test equipment for diode; semiconductor production equipment; automotive electronics; and ECU for V8 engine or V12 engine, etc. The PSU 40-38 provides users with flexible settings of High/Low Level or Trigger input/Trigger output with pulse width of 1 ~ 60ms. Trigger input controls the PSU 40-38 to output or upload preset voltage, current and memory parameters. While outputting or uploading preset voltage, current and memory parameters the PSU 40-38 can produce corresponding Trigger output signals.
