| Content | PSU-Series Overview
Programmable Switching D.C. Power Supply
GW Instek PSU-series power supply with 1U height is highly praised by various markets and it is widely utilized by system integrators. The PSU-series provides 10 models including 6V/200A, 12.5V/120A, 20V/76A, 40V/38A, 60V/25A, 100V/15A, 150V/10A, 300V/5A, 400V/3.8A, and 600V/2.6A. Via 4 units of the same models in parallel connection, the maximum output current at 6V reaches 800A. It meets the demands of low voltage and high current, and high power density. PSU 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, with maximum voltage output of 600V and power output of 1560 watts, 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-series is a single power output DC programmable power supply, which outputs 1200W to 1560W. The PSU-series 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-series 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, PSU-series 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, PSU-series 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-series is ideal for the primary input of DC/DC converter and servo motor production application. PSU-series 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-series provides users with flexible settings of High/Low Level or Trigger input/Trigger output with pulse width of 1 ~ 60ms. Trigger input controls PSU-series to output or upload preset voltage, current and memory parameters. While outputting or uploading preset voltage, current and memory parameters PSU-series can produce corresponding Trigger output signals.
