PXB Series

Bidirectional High-Capacity DC Power Supply

The PXB series of bidirectional high-capacity DC power supplies condenses a 20 kW large-capacity output into a 3U-size chassis. Not only handling high voltages of 1500 V, but also capable of both power and regeneration in both directions in a single unit. We provide a new power supply test environment for electrical and electronic equipment that is becoming increasingly high-powered. In addition, a variety of analog, digital, and communication interfaces are provided for optimal operation at any stage of research, development, and manufacturing! A new generation of bidirectional DC power supplies that support the progression of advanced technologies.
