The PHU series from GW Instek stands for compact, powerful and flexible DC power supplies that have been specially developed for industrial and research-oriented test environments. By using the latest SiC semiconductor technology, the series achieves an exceptional power density. The multi-range output makes it possible to realize different voltage and current combinations with a single device - ideal for versatile applications in development, quality assurance and production.
General features of the series:
- Multi-range technology: One device for variable voltage/current ranges - saves space and investment costs.
- Advanced Web Server (AWS): Full device operation via the browser, platform-independent and without additional software.
- Adaptive Parallel Connection (APC): Flexible scaling through parallel connection of up to 10 devices (max. 150 kW or more depending on the model).
- Extensive interfaces: LAN, USB (type A/B), EtherCAT, CANopen, Modbus, Profinet, DeviceNet.
- Integrated protection and operating functions: CV/CC priority, bleeder circuit, slew rate control, panel lock, internal resistance simulation.
The PHU 1500-30-D model offers a maximum power of 45 kW at 1,500 VDC and up to 30 A output current. It is specially designed for applications with high energy requirements and high voltages, such as those commonly found in e-mobility, energy technology and power electronics. Typical areas of application include:
- Testing of DC charging systems and high-voltage components in the field of e-mobility
- Simulation of solar generators for string and central inverters
- Ageing and load tests of stationary high-voltageenergy storage systems
- DC supply and intermediate switching tests in industrial power converters
- Validation of insulation concepts and overvoltage protection in high-voltage technology
