Sukura [india] supplies noblack, a programmable street light control switch, designed to control the street lighting/electrical load automatically as per the timings programmed in the system. The on/off timings will change automatically 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.
Main features: housed in sheet metal enclosure, properly treated and duly [powder coated] conforming to degree of protection ip 54 of is: 12063/1987 [reaffirmed 1999]; suitable to operate on single-phase ac voltage 160 v to 260 v, 50 ±3 hz; able to switch on and off the street light at rated load at rated power factor at predetermined time; automatic on/off switching timer records remain in the memory even in power failure conditions; records set in memory are on monthly basis; and power saving up to 40%. Applications: single phase to single phase - the unit works in three phases- single phase single phase, single phase three phase loads and three phase to three phase loads.
The single-phase supply controls the single-phase loads. The single to three phase loads controls on three phase loads. Optionally the three phase- three phase- on this one of the three phases shares the load and controls all the three phases.
