The PHU series from GW Instek combines modern SiC technology with a multi-range output concept that enables maximum flexibility with minimum space requirements. The devices are designed for demanding test and development applications, particularly in the fields of electromobility, photovoltaics, battery simulation and industrial power electronics. Thanks to extensive control options and the integrated web interface, the power supply units can be seamlessly integrated into automated test systems.
General features of the series:
- Multi-range output: Wide range of voltage and current combinations with one device.
- Advanced Web Server (AWS): Device operation directly via the web browser - without software installation.
- Adaptive Parallel Connection (APC): Parallel connection of up to 10 devices for outputs of up to 150 kW.
- Multiple interfaces: LAN, USB (type A/B), EtherCAT, CANopen, Modbus, Profinet, DeviceNet.
- Safety and convenience functions: Bleeder circuit, programmable slew rate, CV/CC priority, internal resistance simulation, panel lock.
The PHU 200-140-D model offers an output power of 15 kW with a voltage range up to 200 VDC and a maximum current of 140 A. This model is particularly suitable for applications where high currents are required at a comparatively low voltage. Typical areas of application are:
- Testing of DC low-voltage components in vehicles and industrial plants
- Simulation of battery modules with high current loads
- Testing of low-voltage DC motors and electronic loads
- Characterization of power supplies, converters and busbars
- Test environments for electronic control units (ECUs) with current requirements up to 140 A
