Data retention for 10 years

Patented product; enclosure designed for horizontal DIN rail mounting

3.Application Range:

ET series computer/controller units can, according to user-defined times (latitude/longitude and illuminance thresholds), independently control the power supply of electrical devices. Widely used for street lamps, landscape lighting, neon signs, and advertising lights—devices that require time-based power on/off control.

Users can configure four sets of on/off schedules to realize multi-interval lighting control. Alternatively, by using the local latitude and longitude, time-based switching can be date-aware. The controller can also employ a light sensor to measure ambient illuminance and switch lights on or off based on illumination levels.
