The UltraVolt Dual Polarity C series includes seven dual-output models ranging from ±125 to ±6000 VDC of maximum high voltage power. Each pair offers both a positive and negative polarity in a single package. From a 24 VDC input, access up to 250 W of total fast-rise charging power with less than 1% overshoot. Each output is individually controlled using an analog interface. Meet specific application needs by selecting mechanical integration options. Typical applications for the Dual Polarity C series include cap charging, pulsed power, ultrasound, amplifiers, and pulse generators.


  • Increase system throughput with quick capacitor charging
