4.5 Power supply selection for RDG200KN
The RDG200KN can be powered either in AC 230 V or AC 24 V.
The desired power supply needs to be selected via the power switch located in 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 will be damaged if it is set as AC 24 V but powered with AC 230 V.
To select the right power supply needed, use the power switch located in the rear
of the device.
