HIGH VOLTAGE CAP-CHARGING SUPPLIES
ULTRAVOLT® C SERIES
DC-to-HVDC
single-output
high voltage cap-
charging modules
The C series of high voltage regulated DC-to-DC
converters are designed for fast rise time/charging
applications utilizing state-of-the-art power conversion
topology.
This high power density module is especially
suited to high-energy pulsers, amplifiers, and discharge
devices with large capacitance, fast repetition rates,
or high current loads. Surface-mount technology and
encapsulation techniques provide high reliability
and low cost.
Features
› 7 models from 0 to 125 V
through 0 to 6 kV
› 20 or 30 W output power
› Maximum Iout capability down
to 0 V
› Maximum Iout during
charge/rise time
› Indefinite output short circuit
protection
› Very fast rise with very low
overshoot
› Output voltage and current
monitors
› > 400,000 h MTBF at 65°C
› Fixed-frequency,
low-stored-energy design
› UL/cUL recognized
component; CE Mark (LVD and
RoHS)
Typical Applications
› Cap-charging
› Pulsed power
› Test equipment
› Mass spectrometry
› Automated test equipment
(ATE)
› Lasers and electro-optics
