Power supplies for engineers designing at higher voltages

XP Power continues to make high power flexible for ease of integration across multiple platforms by expanding the reach of its HPT5K0 series with the addition of 400VDC and 800VDC models. These new additions cater to engineers designing at higher voltages, including those involved in battery charging, renewable energy, and semiconductor manufacturing equipment.

All models in the series of programmable, scalable, and configurable AC/DC power supplies, which now span from 48VDC to 800VDC, deliver 5kW of output power from a three-phase, three-wire, and earthed 180VAC to 528VAC input. This simplifies installation as there is no requirement for a neutral connection, which is often unavailable in industrial applications. The safety interlock feature enhances safety by providing a safety-stop control that is independent of software, with signal inputs and outputs ready for integration with an industrial safety controller.

The device supports I²C, RS232 and RS485 serial buses with multiple digital protocols, including PMBus, CANopen, Modbus, and SCPI. The ability to programme constant voltage from 0% to 105% and constant current from 0% to 110% offers design flexibility, accommodating a wide range of loads. Additionally, the firmware can be configured through the GUI, enabling application design flexibility and tailored system integration that adapts to specific user needs.

The extensive in-built user-defined monitoring and digital controls, such as active current sharing, remote on/off, and AC/DC OK signals, contribute to an optimised system design, which can lead to decreased maintenance and operating costs, streamlining the overall efficiency of operations. Moreover, the provision of fully isolated digital communication ensures equipment and user safety while also improving the reliability of the system.

The active current sharing capability of up to 25kW facilitates easy scalability, making it more straightforward to cater to higher-power applications without notable redesign or investment. Furthermore, achieving up to 94% efficiency in operation reduces waste heat dissipation, helping to minimise operating costs and making the system not only effective but also economical in the long run.

The company conducts extensive verification testing and quality controls to ensure long-lasting reliability. The HPT5K0 meets EN61000-4 immunity for greater reliability in harsh electrical environments and complies with the EN55032 EMC standards for conducted (Class B) and radiated (Class A) emissions. These and industrial safety certifications help ease system integration, speeding up the process of acquiring system-level approvals.
