The UltraVolt C series includes seven models ranging from 125 to 6,000 VDC of maximum high voltage power. They C series models are available in single-output positive or negative polarities. From a 24 VDC input, access up to 30 W of fast-rise charging power with less than 1% overshoot. Choose from PCB or chassis mounts and select mechanical and electrical performance options to meet your specific application needs.

Advanced Energy's UltraVolt C series is ideal for high-energy pulsers, amplifiers, and discharge devices with large capacitance, fast repetition rates, or high-current loads.
