SC2A4-80L

The transformer has two five-step switches for setting two voltage levels. Switching between the set voltages takes place with e.g. timer or thermostat. Signal light on the front indicates operation. If several fans are connected, the sum of the motors' maximum currents must not exceed the rated current of the transformer. Voltage output 230 VAC for e.g. operation indication or damper motor. 2 connectors for remote control to / from RT-RT, FS-FS (normally closed). Automatic restart after power failure. Motors equipped with an extended thermal contact must be connected to the built-in thermal contact motor protection.
