The twilight switch WZM-02 is used to control lighting devices and other energy receivers depending on luminous flux density.
The system switches on the lighting at dusk and switches off at dawn.
The device is equipped with two illuminuous flux density ranges where the switching on threshold can be adjusted by the user.
The system has the continuous output (load) switch on function (ON) , connected to output (load) relay terminals, and the automatic function (AUTO). External luminous flux density sensor SOH with a cable of 50 m maximum length enables the sensor to be put in a suitable place.
- Receivers controll depending on illuminous flux density
- Input rated indicator
- Relay indicator
- Illuminuous flux density range choice
- Adjustment of the switch on threshold
- Automatic work mode (AUTO) or continuous work mode (ON)
- Resistant to momentary changes of luminous flux density
