Air Conditioner Energy Saver

ENERGY SAVING up To 20% can be achieved using our SEQUENTIAL CONTROLLERS. Energy saving can be optimized by choosing appropriate program to meet the specific need among the various programs available.

The SEQUENTIAL CONTROLLERS and timers are designed using real time clock which has got nonvolatile memory, hence power interruption of any duration will not call for reprogramming or manual intervention. These controllers are programmed to switch OFF all the Air Conditioners during off peak hours resulting in more Energy saving.

Universal Timer is an ideal device to switch On & Off the load without any manual interference.

This device is based on RTC. It can be programmed according to the user requirement. it will operate with a time interval of 30 min or 60min duration, the duration of on time & off time can be selected by the position of DIP switches provided.

This can be used for operating aviation lamps air conditioners, glow sign boards and all lighting applications or industry and domestic.
