Switch Mode Power Supplies-Water Cooled
The MSW Rectifiers are based on Switch Mode Technology. This reliable technology assures excellent quality DC currents with a ripple of < 3% and a control accuracy of less than 1%.The MS-Series features constant voltage and current control with easy, quick installation and maintenance. Modular versions easily increase the output by means of series or parallel connection. All models have DC short circuit protection. With forced air-cooled models, the cooling air quantity is controlled in relation to the load reducing contamination and noise levels.
