The new and improved 303 series capacitor charging supplies are one of the highest power units available in a single package. The advanced water cooled design allows an average capacitor charging power of 30kJ/sec (or 50kW continuous DC) to be realized from a 12.25" high supply. Multiple product upgrades have resulted in improved reliability and added product features, such as optional current programming, constant power mode for charging large load capacitors, and a current bar graph for models with the slave front panel.

The 203 uses an advanced fluid based cooling technique. The coolant is an inert fluorinated hydrocarbon (non CFC) fluid which is a liquid at room temperature but boils at a relatively low 59°C. All of the high power and high voltage electronics in the supply are immersed in the coolant which serves both to cool and insulate the components. As a component heats up, the coolant in contact with it vaporizes and it is this liquid to vapor phase transition which efficiently removes the excess heat from the components. The coolant vapor is cooled by a heat exchanger located in the area above the fluid. This cooling technique allows very high power electronics to operate continuously and reliably in a very small volume.
