The PHU series from GW Instek offers state-of-the-art high-performance DC voltage sources for a wide range of industrial and research-related applications. With their multi-range functionality and compact design based on SiC technology, these devices combine maximum flexibility with excellent power density. Thanks to the integrated web server and extensive communication interfaces, they are ideal for use in automated test benches and complex test systems.
General features of the series:
- Multi-range output: One device covers several voltage/current ranges, ideal for versatile test scenarios.
- Advanced Web Server (AWS): Intuitive remote control via the browser without additional software.
- Adaptive Parallel Connection (APC): Multiple devices can be flexibly interconnected, up to 150 kW total output.
- Broad range of interfaces: LAN, USB (type A/B), EtherCAT, CANopen, Modbus, Profinet, DeviceNet.
- Safety and convenience functions: Bleeder switching, programmable slew rate, CV/CC prioritization, load simulation and panel lock.
The PHU 1000-45-D model is the most powerful single variant in the series with a maximum output power of 45 kW at up to 1,000 VDC voltage. This makes it ideal for applications with extremely high energy requirements and large currents. Typical application scenarios are
- Development and testing of large-scale electric drives for commercial vehicles or industrial drives
- Simulation and load tests for fast charging infrastructure up to 45 kW charging power
- Large-scale PV system simulation in research, development and certification
- Automated test systems for battery packs, energy storage systems (ESS) and DC microgrids
- High-performance test benches in automotive, aerospace and energy technology
