The PHU series from GW Instek is specially designed for demanding applications in electrical power supply, power electronics, e-mobility and research. Thanks to the multi-range output function and state-of-the-art SiC semiconductor technology, the devices deliver high performance in a compact design. An integrated web server and a variety of communication interfaces enable simple control and seamless integration into modern test and automation systems.
General features of the series:
- Multi-range output: Flexible combinations of voltage and current in one device.
- Advanced Web Server (AWS): Intuitive operation via the browser without additional software.
- Adaptive Parallel Connection (APC): Can be combined with up to 10 devices for extended performance requirements.
- Comprehensive interfaces: LAN, USB (type A/B), EtherCAT, CANopen, Modbus, Profinet, DeviceNet.
- Convenience and protection functions: CV/CC priority, bleeder switching, slew rate control, resistance simulation, panel lock.
The PHU 200-70-D model offers a maximum output power of 15 kW at 200 VDC voltage and up to 70 A output current. It is ideal for applications with a medium voltage range and high current requirements, particularly in automotive and industrial electronics. Typical areas of application are:
