4.5 Power supply selection for RDG200KN
The RDG200KN can be powered either on AC 230 V or AC 24 V.
The desired power supply is selected via the power switch on the rear of the device.
The default setting is AC 230 V.
Therefore, RDG200KN can be used with the following combinations:
● AC 230 V or AC 24 V systems with 3-speed and DC 0…10 V fan control
● SELV AC 24 V systems with PWM AC 24 V electrothermal actuators
Notes:
The outputs (triacs and relays) follow the main power supply, either AC 230 V or
AC 24 V.
The device is damaged when set to AC 24 V but powered by AC 230 V.
To select the correct power supply, use the power switch on the rear of the device.
