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.

Selenium Surge Suppressor
-
Surge suppressors are used to protecting circuits from transients (sudden, brief increases in voltage). Transients of widely varying magnitudes are caused by such circuit components as motors, coils, magnets, relays, and transformers. They are found in all electrical systems and are notorious for damaging diodes, SCRs, transformers, triacs, and relay contacts.

Bridge Rectifier Assemblies
-
Bridge Rectifier Assemblies are constructed by packaging diodes and/or SCR components with heat sink extrusions in a bridge circuit.CEHCO uses M, T, N and W heat sink extrusions to build rectifier assemblies.

High Voltage Diode Assemblies
-
High voltage diode assemblies are built by adding diodes in series to yield a higher peak inverse voltage. For example, if each diode is rated for 1200 peak inverse voltage (PIV), then six diodes in series would have a total peak inverse voltage of 7200 PIV. The detailed circuit is shown below.
