Programmable Street Light Control Switches

Description: Programmable Street Light Control Switches are designed to control the street lighting/electrical load automatically as per the timings programmed in the system. The On/Off timings get automatically changed every month. Noblack comes with a factory default and a user defined program in the system. The built-in over/under voltage protection mechanism protects the street lighting/electrical load from high and low voltage. This system disconnects the load immediately within 20 milliseconds, once the high/low voltage is sensed and connects the lighting load automatically when the normal voltage is restored. The main features include housed in sheet metal enclosure, properly treated and duly (powder coated) conforming to degree of protection IP 54 of IS: 12063/ 1987 (reaffirmed 1999). It is suitable to operate on single-phase AC voltage 160 V to 260 V, 50 ±3 Hz. It is able to switch on and off the street light at rated load at rated power factor at predetermined time. The automatic on/off switching timer records remain in the memory even in power failure conditions as well as records set in memory are on monthly basis and has the capacity of saving power up to 40%. It is used in applications such as single phase to single phase, where the unit works with single-phase supply and controls the single phase loads, single phase to three phase, where the unit works with single-phase supply and controls the three phase loads, three phase to three phase (optional), where the unit works with one of the three phases, it controls on the three phase loads.
