The PHU series from GW Instek was developed for versatile and demanding applications in the field of DC power supply. Based on SiC technology, it combines high power density with a multi-range output that enables variable voltage and current combinations. The devices are ideal for test benches, research laboratories, industrial test environments and automated systems that require a flexible, scalable and remotely controlled DC power source.
General features of the series:
- Multi-range output: Dynamic voltage/current adjustment for different test conditions.
- Advanced Web Server (AWS): Easy operation and monitoring via the browser - without software installation.
- Adaptive Parallel Connection (APC): Parallel connection of up to 10 devices for high total outputs of up to 150 kW.
- Versatile interfaces: LAN, USB (type A/B), EtherCAT, CANopen, Modbus, Profinet, DeviceNet.
- Protection and ease of use: CV/CC priority, bleeder circuit, slew rate control, panel lock, internal resistance simulation.
The PHU 500-30-D model offers an output power of 15 kW with a voltage range up to 500 VDC and a maximum current of 30 A. It is particularly suitable for applications with medium voltage and moderate current requirements, such as those frequently found in automotive technology, power electronics and industrial automation. Typical fields of application are:
- Tests of DC-DC converters, inverters and 400 V components
- Testing of drives and control units for hybrid and electric vehicles
- Simulation of battery systems in the medium voltage range
- Power supply for test fields and production stations with flexible requirements
- General development and quality assurance applications in power electronics
