RVM Series of SCR power controllers comes in three-phase and single-phase versions rated for 40 A at 660 V ac. Series offers zero-cross firing for fixed resistance loads, is almost silent in operation, and can eliminate the switch-on surge by operating in synchronization with the supply. RVM family uses a performance-engineered heat sink and thermal transfer technology so that it can be installed on a DIN rail with only 0.18 in. between relays. Series is well suited for replacing electromechanical relays in heating applications, such as industrial ovens, hot presses, environmental chambers, and drying applications.
