Voltage range: 220-240V AC 50/60Hz
Rated voltage: 230V AC
Operating power consumption: ≤2W @230V AC
Output signal: One way ON/OFF switch (16A relay) + one way 0-10V dimming port
Lightning surge: 2KV (L/N,EN61000-4-5)
Load surge current limit: 30A (tested at 50% Ipeak, twidth 500us @220Vac, cold start at full load)
Maximum load of ON/OFF port: 1200w resistive load, 600w capacitive load

Sensing method: 24G Hz millimeter wave radar + light detection
Detection Area: Knob potentiometer/remote control setting: radius 0.5m-4m
Delay setting (Hold Time): Knob potentiometer/remote control setting: 10s/30s/1min/3min/5min/10min/20min/30min
Standby Time: Knob potentiometer/remote control setting: 0s/10s/1min/3min/5min/10min/30min/+∞
Daylight Sensor: Knob potentiometer/remote control setting: 5Lux/15Lux/30Lux/50Lux/100Lux/150Lux/Disable
0-10V port dimming ratio: 10%/20%/30%/50%
Light environment adaptive (Daylight Harvesting): Supported, dimming range 50%-100%. When the ambient illumination is higher than 800Lux, the sensor will forcibly turn off the lights. After the shutdown, the sensor can be turned on when the ambient illumination is lower than 100Lux.
Detection range (4m gear, medium sensitivity): Movement/micro-motion/breathing sensing distance (3m high): radius 3.5m±0.5m (based on the indoor open 41㎡ space test and moving radially towards the sensor at a speed of 1m/s. The sensing distance may fluctuate slightly in different environments)
Remote control function: Support (MH10/MH18 remote control)
Installation height: 2-4m Typical value: 3m
