Rectangular Electric PSCS Single Phase Switch, Rated Power : 5KW

real time clock:
programmable street light control switch has in built real time clock with battery backup sufficient for five years minimum. It displays the day and date along with on and off time, on led display and maintain the timing accuracy of ± 1 (one) second over the entire range of environmental operating conditions.

programming features:

• switch on and off the streetlight loads, at rated power factor at pre-determined time.
• have facilities of default program (company installed)based on “astronomical timer” means daily change of program as per sun rise and sunset timing, as well as pre-
• defined (user programmable) to pre-program and switch the on and off time for one year with minimum 12 programs, spread over a year.
• streetlight on / off timing accuracy is maintained within 60 seconds from preset time under the entire range of environment conditions.
•  facilities to switch on/off the streetlight loads, manually by-passing the programmed circuit.

protection:

• over voltage / under voltage:
• have protection from over voltage i.e. Load switch off when voltage goes above 260±5v (adjustable at factory end) and auto restart when normal voltage is sensed i.e. 250±5v.
• have protection form under voltage i.e. Load switch off when voltage goes below 160±5v
• (adjustable at factory end) and auto restart when normal voltage is sensed i.e. 180±5v.

over load and short circuit protection:
