The PHU series from GW Instek is a modular, high-performance solution for demanding DC applications in research, development and production. The devices are based on modern SiC technology and have a multi-range output that allows flexible adjustment of voltage and current. With its compact design, intuitive remote control via the integrated web server and a wide range of interfaces, the PHU series can be easily integrated into existing test and automation environments.
General features of the series:
- Multi-range output: Flexible voltage/current ranges - one device for many requirements.
- Advanced Web Server (AWS): Convenient control and monitoring via the browser - without additional software.
- Adaptive Parallel Connection (APC): Up to 10 devices can be cascaded - total power up to 450 kW (depending on model).
- Multiple interfaces: LAN, USB (type A/B), EtherCAT, CANopen, Modbus, Profinet, DeviceNet.
- Comfort and safety functions: Bleeder circuit, programmable slew rate, CV/CC priority, panel lock, resistance simulation.
The PHU 750-40-D model offers an output power of 30 kW with up to 750 VDC voltage and a maximum output current of 40 A. It is ideal for high-voltage applications in the field of electromobility, industrial energy systems and the development of high-performance converters. Typical areas of application are:
- Tests and simulation of high-voltage battery systems (e.g. 700-800 V) in e-mobility
- Characterization of 750 V inverters, DC/DC converters and power supply units
- DC power supply and DC link simulation in test benches for power electronic systems
- Development and life tests of components in industrial and energy technology
- Use in automated test systems with medium to high power requirements
