SCR Rectifiers
-
SCR-controlled rectifiers are electronically controlled via analog signals for constant voltage and current control. The compact and service-friendly design complies with high industrial requirements and guarantees excellent operational reliability.The input voltage can be from 208 VAC to 600 VAC, 3 PH, 50/60 Hz. Maximum output voltage can be from 6 VDC to 600 VDC. Maximum output can be from 1000 Amps to 100000 Amps. These units can be air cooled, water cooled or oil cooled.

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.

SCR CONTROLLED DC POWER SUPPLY
PS Series
-
Variable DC power supplies are AC to DC power supplies with a variable DC output. The output can be varied with an SCR controller. The AC input power can be single phase or three phases. With single phase AC input, the DC output ripple is very high (50%). With three phase AC input, the DC output ripple is low (5%). This would be a key benefit for selecting three phase AC input instead of single phase.

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.
