The PHU series from GW Instek stands for powerful, compact and versatile DC voltage sources. Thanks to modern SiC technology and a multi-range output, various voltage/current combinations can be flexibly realized. These features, combined with intuitive remote control via the integrated web server and numerous industrial interfaces, make the PHU series the ideal choice for laboratories, test benches and automated test systems.
General features of the series:
- Multi-range output: One power supply unit - many voltage/current configurations depending on requirements.
- Advanced Web Server (AWS): Control via the browser - without additional software.
- Adaptive Parallel Connection (APC): Scalability through parallel connection of up to 10 devices.
- Extensive communication interfaces: LAN, USB (type A/B), EtherCAT, CANopen, Modbus, Profinet, DeviceNet.
- Convenience and safety functions: CV/CC priority, programmable slew rate, bleeder circuit, internal resistance simulation, panel lock.
The PHU 750-20-D model offers an output power of 15 kW at a maximum voltage of 750 VDC and an output current of up to 20 A. It is particularly suitable for applications in the upper medium voltage range with moderate current requirements, as is common in automotive technology, solar simulation and industrial power electronics. Typical areas of application:
- Simulation of battery modules for high-voltage vehicles (e.g. 700-800 V systems)
- Tests of 750 V inverters and DC-DC converters
- Characterization of PV components and charging electronics
- Power supply and testing of components in industrial automation
- Integration into modular test systems with medium-high voltage/power requirements
