All features of Street Light Controller with staggering
Protects the system from Over voltage, Under voltage, Over current, Short circuit, Neutral Open (optional)
HMI LCD display. 16 character and two line type display
Multi – Function Panel mounted Energy meter class 1 type which continuous scrolling display of individual phase voltage, load amps, PF, KW, KVA, KVAR, Phase to Phase voltage, Average PF, KWH etc. (Optional)
It has inbuilt auto recovery systems for power failure which helps in streetlight operation
Auto Calibration of Systems for monitoring Load current for protection
Even in single phase control systems will work. Power redundancy for controller even 1 phase 170 VAC controller can work
Over and under voltage cut off user settable. Saves lamps and energy. Auto reset type over voltage and under voltage cut off
Electronic sort circuit protection
Settable incoming Neutral open alarm for specially when unbalance load. (Optional for protection Which protect lamps against high voltage.)

Over current trip in % is user settable. It has special function to store load current of each line & channel in memory. When over load will be detected it will trip that particular phase after define retries.
