B&K Precision Launches High-Efficiency 20 kW DC Power Supply

Power Supplies Test and Measurement

B&K Precision, a global provider of reliable, cost-effective test and measurement instruments, has announced the introduction of its HPS Series, a new 20 kW DC power supply family. Offered in two models, the HPS Series features a high-power density3U form factor, 94% efficiency, and a voltage output of up to 1500 V, meeting the demanding requirements of industrial, aerospace, and EV applications.

The HPS Series includes:

  • HPS20K800 (800 V / 25 A)
  • HPS20K1500 (1500 V / 13.4 A)

Multiple HPS Series models can be combined in parallel to increase total output power up to 160 kW, providing flexibility for high-power applications. The series is further equipped with a 5-inch touchscreen display, offering an intuitive user interface to set and measure values while also simulating internal resistance. The unit’s front panel USB host port allows for direct voltage and current data logging.


Comprehensive Connectivity & Protection Features

The galvanically isolated analog interface enables external voltage source-based output control and monitoring. To enhance safety and prevent damage to both the power supply and the device under test, the HPS Series incorporates comprehensive protection features, including Overvoltage Protection (OVP), Overcurrent Protection (OCP), Overpower Protection (OPP), Undervoltage Protection (UVP), and a Key Lock Function.

Additional key performance attributes include efficiency up to 94% for optimized power usage, fast transient response time (<3 ms), adjustable voltage and current rise time, photovoltaic array simulation capabilities, remote sense function to compensate for voltage drop, data logging directly to USB flash drive, LabVIEW drivers for streamlined integration, and 3-phase 208 VAC or 400 VAC input configurations.


Availability & Pricing

The HPS20K800 and HPS20K1500 models are available now at a list price of $16,700 each, backed by a 3-year standard warranty.
