WS2003 Cascade

Constant Current Controls with up to 16 SCRs

The WS2003 Cascade is an advanced controller that can fire up to 16 SCRs in Cascade fashion. Because of its highly modular construction, it lends itself to integration into customer control cabinets and retrofits, as well as completely self-contained applications. The variety of "add on" accessories makes this controller one of the most versatile on the market.
