DC Filter Inductors
-
Osborne DC filter inductors (aka filter chokes) are commonly used in AC to DC conversion circuits to present an inductive voltage drop to the AC component of rectified current. This inductive voltage drop acts as a filter. Osborne designs filter inductors to components to function effectively (without saturation) in the presence of the DC current. Osborne will work with you to mitigate the impact of ripple frequency in conversion circuits. Every Osborne DC filter choke is designed for high performance with special consideration given to your circuit´s power supply frequency and conversion configuration.

IGBT Power Supplies - Air Cooled
-
CEHCO The MSA1000 Rectifiers are based on IGBT 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.
