Three-phase 5 kW power supply

26 June 2019 Power Electronics / Power Management

XP Power’s HPT5K0 series is a range of high power density, high efficiency, resonant zero-voltage switching (ZVS) 5 kW AC-DC power supplies with both ITE/industrial and medical agency approvals that feature a three-phase, three-wire, 180 to 528 V a.c. input. This simplifies installation as there is no need for a neutral connection, which is often not available in industrial applications.

Integrated digital control allows the setting of both the output voltage (0-105%) and output current (0-110%) via both analog and digital control interfaces. A graphical user interface (GUI) is also provided to support system development and define unique user profiles, allowing tailoring of the units to the end application, including signals and controls, without hardware changes. This capability also allows the same base unit to be used across multiple applications, reducing cost by driving economies of scale.

The HPT5K0 series supports I²C, RS232 and RS485 serial buses, with multiple digital protocols including PMBus, CANopen, MODBUS and SCPI, offering flexibility to designers. Full documentation is provided.

Packaged in a compact chassis mount package measuring 330,2 x 127,0 x 127,0 mm, the supplies offer high power density and efficiency levels up to 94%. They can be configured in series or in parallel with full current sharing, providing a flexible building block for developing high-power systems up to 25 kW with output voltages from 48 V to 400 V d.c.

The HPT5K0 series is suitable for a broad range of industrial, technology, semiconductor fabrication and medical applications, including high-power LED applications such as UV curing and heating, burn-in equipment, lasers, motor controllers, industrial printing (2D and 3D), EV charging, test equipment, battery simulation and medical imaging devices. The power supplies feature very fast output slew rates of less than 40 ms, making them well suited to challenging test applications. A thermally-controlled fan keeps the units cool with minimal audible noise.

The power supplies are designed and qualified for EMC immunity in harsh electrical environments and emissions are class B for conducted and class A for radiated, ensuring reliable operation and ease of integration, speeding up the process of obtaining system level approvals. They are offered with a three-year warranty.
