If you’re looking for a way to cut back on the amount of energy used on your office air-conditioning, then the Smart Energy Sensor is an ideal add on to your current or future air-conditioning installation. It’s a simple solution to an ongoing problem of leaving your air-conditioner on while you are out of the office or even forgetting it on when going home at night.
This little piece of energy efficient equipment simply connects to your main power going into the air-conditioner and then by means of a passive infra-red motion detector cuts off the power if there is no movement in the office for a preset period. There are 5 preset periods available 5, 10, 20, 40 and 120minutes. This means that if there is no movement for say 5 minutes, the power will be cut to your air-conditioner.
The Smart Energy Sensor has a 1 minute delay on initial power up, this protects the Air-Conditioner against in-rush currents when load shedding recovers. The sensor which has an 8m range can be wall or roof mounted and has built in protection against power surges and over current occasions. The relay is capable of handling up to 30A 220V and anything larger than that can be controlled by means of an external relay.
So how much energy can you save, well that is an impossible question to answer but If you are able to switch your air-conditioner off for 3 hours in a day while it is not needed, that equates to around a R180 saving a month when you do this for 20 days of the month. This smart Energy Sensor will pay itself off in no time at all.
