SSR and Solid State Relays - GEFRAN - #7

Text version of the page

GI: MOTOR CONTROLLER Three-phase power solid state relay specifically to control 3-phase asynchronous motors in both directions with non- simultaneous control. Applications: gate motors, conveyor belt motors GI W211, W212, W312, W401: power solid state relays for heavy-duty applications ° C to +50 ° C, current up to 600 Amps,and voltage up to 660 Vac.W211 and W212 have “zero crossing” activation, control signals in Vdc, Vac (W211) and analog signals (W212), optionaldiagnostic functions for load current, with adjustable current setpoint and alarm output. They can be used in synchronized master-slave configurations for single-phase and 3-phase configurations.W312 accepts analog control signals and checks load via “phase angle” activation, with power soft-start at switch-on. The W401 series receives the control signal via RS485 serial communication line, with Modbus protocol (for networksup to 16 nodes), has real-value current and load voltage converters for remote checking and diagnostics of loads by meansof “recipes” managed by a supervisor. The models in the WATTCOR family have extremely sturdy thyristors and outstanding heat dissipation, which makes them perfect for heavy-duty industrial applications with working temperatures from –5 Applications: ovens, heat treatments (W211, W212) transformer primaries, infrared heaters (W312) tyre machines and production lines, electrical cables (W401)
