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.

Replacement Selenium Surge Suppressor Specialists
-
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.

MRI POWER SUPPLIES
-
MRI Power Supplies are used in MRI Imaging rooms in hospital environment. The lights in the MRI rooms require DC power. If AC power is used, the quality of the MRI imaging process is compromised. These units are ideal for MRI room, where a 60 Hz flicker free light environment is desired. CEHCO offers four models which are shown below.
