This is a freshly refurbished Maxwell General Atomics CCDS 310-P-1-208 Capacitor Charging Power Supply. The CCDS Series of high voltage switching power supplies is designed to quickly charge capacitors, either small capacitances at high repetition rates, or large capacitor banks at low repetition rates. High frequency switchmode technology provides a compact and lightweight reliable power supply with a constant current, linear charging profile. All Maxwell CCDS family models feature an EMI filter, an inrush current limit circuit, along with high temperature, overcurrent and overvoltage protection.

  • User Manual

The many standard features and options make this series useful for laboratory and commercial applications such as lasers, medical accelerators, pulse generators, and high voltage test facilities. Designed for continuous use, these air-cooled power supplies provide an average charging rate of 3 kJ/s. Output control and status monitoring are accomplished with the standard remote control interface.

CCDS power supplies provide high regulation with the use of a patented topology that reduces the size of the quantum of charge (also called the "bucket" of energy) delivered at the end of the charging cycle. CCDS supplies are inherently current sources due to their topology, which makes them very easy to parallel.

In the CCDS line of power supplies, the control topology is designed so that the power supply operates as a constant current source into the capacitive load with an autocrossover point at the output voltage set point. The voltage on the capacitor then rises linearly until the desired setpoint voltage is achieved, at which point the power supply switches operating modes so that the power supply only provides enough "keep-alive" current to the capacitor to regulate the output voltage.
