Functions and features:
 Controlling the switches of street lamps
 PWM or DC voltage of 0-10V output to adjust lamp's brightness
 Collect values of current and voltage to calculate power factor and consumption
 Alarm when line power over/under-voltage and lamps abnormal or faulty (SOS switch: optional)
 Operating temperature (-40-85°C)
