The “C” Series of high-voltage regulated DC-DC converters are designed for fast rise-time/charging applications utilizing state-of-the-art power conversion topology. The power stage is protected from output current overloads or short circuits via a secondary current limit circuit. This current limit is optimised for low-impedance capacitor charging. The high voltage developed in the multistage multiplier generates feedback voltage, which is sent to the CTRL circuit to maintain regulation. The AC feedback networks are configured for maximum speed of rise with little or no overshoot into capacitive loads. The “C” Series is designed for full DC power operation at up to 92% efficiency. A wide input range of +23 to +30VDC maintains full output power. The derated input range is +9 to +32VDC. Output voltage is adjustable from 0 to 62V, 125V, 250V, 500V, 1kV, 2kV, 4kV or 6kV. The output polarity is specified at the time of ordering. The monitor output impedance is calibrated for use with a 10 MegΩ input impedance meter. Overall accuracy is ±2.0% with a temperature coefficient of ±200 ppm per °C. The output voltage is adjustable from 0 to the rated max output voltage using a 5V reference signal.
“C” Series converters are in PCB-mountable plastic cases requiring a footprint of 5.5 in² and only 4.3 in³ of volume. Mounting plates and brackets are available for chassis mounting. This series is also available in an RF-tight metal PCB/chassis mount package.
The “ C ” Series provides full power operation at case temperatures from -40 to +65°C. All units receive a 24-hour burn-in prior to final testing.
