The PHU series from GW Instek offers powerful DC voltage sources with high flexibility, compact design and intuitive controllability. Based on efficient SiC semiconductor technology and equipped with a multi-range output, the devices can be used in a wide range of test and simulation scenarios - from research and development to industrial series testing. Thanks to the integrated web interface and extensive interface integration, the PHU series is ideally equipped for modern test environments.
General features of the series:
- Multi-range output: Flexible working with different current/voltage combinations.
- Advanced Web Server (AWS): Complete remote control via the browser - no additional software required.
- Adaptive Parallel Connection (APC): Scalable up to 10 devices - for total systems with up to 450 kW power (depending on model).
- Broad interface support: LAN, USB (type A/B), EtherCAT, CANopen, Modbus, Profinet, DeviceNet.
- Intelligent protection and convenience functions: CV/CC priority, programmable slew rate, bleeder circuit, panel lock, internal resistance simulation.
