Power Controllers

Watlow solid state power controllers complement the rapid switching required by PID temperature controls and help deliver optimum system performance and service life. Available in 1-phase and 3-phase/2-leg and 3-leg configuration, Watlow power controllers meet most industrial heating applications. Random, zero cross or phase angle fire options match power controller to the application requirement. DIN-A-MITE® SCR power controllers provide a convenient DIN rail mount package in current ratings from 18 to 100 amperes -- a good replacement for equal mercury displacement relays. QPAC SCR power controllers rated up to 1,000 amperes for those large process heating applications. POWER SERIES microprocessor based SCR power controllers with ratings from 65 to 250 amperes. The POWER SERIES offers extensive system and heater diagnostics features and agency approvals. SERIES CZR is a CSA, VDE and UL® recognized contactor with ratings from 18 to 50 amperes single phase. Single solid state relays from 10 to 75 amperes. E-SAFE® II relay is a 3 pole hybrid solid state/mechanical relay with current ratings up to 35 amperes. E-SAFE II is an excellent mercury displacement relay replacement.
