Time Delay between two consecutive power ON for split A/C

Postby sv5020 » Mon Mar 19, 2012 4:01 am

Hello-

I need to install a 1 Ton split A/C soon and I've got a 5kVA servo stabilizer serving the entire home. Do I need to have a separate voltage stabilizer for the A/C unit ? The existing servo-stabilizer has a power on delay 1 sec to 5 mins-selectable range. So my question how much time Delay between two consecutive power ON for split A/C is advisable for the better life of compressor ? Or time delay doesn't matter and only high/low voltage protection is sufficient for split A/C's ? Pls advise.

The Ac system needs to have a dedicated power supply. I don't know if that answers your ques5tion or knot however.

Hi there...I live in a place where we have frequent power failure. My Qn is applicable only when there is a power fluctuation ie, the power goes and come back within a minute duration and if it repeats. I heard such a scenario can make the compressor over heated and can reduce the life. So is there necessity for a time delay relay for the A/C ? Here usually people install an additional stabilizer to the A/C unit and many of these stabilizers have a built in time delay of 2 to 3 minutes. If the power flips, the stabilizer will supply power only after this delay. Also there is no delay if the power resumes after 5 minutes or more. Is this delayed start an important factor...? if yes, I need to include just a relay device to the A/C.

All compressors should have a delay. You sound like you need a surge protector also.

Thanks, Heatseeker. The main servo stabilizer has a built in surge protector so, that part is covered. I'll fix a time delay relay to the A/C unit. cheers

I suggest you invest in thermostat with a built in delay of at least 5 minutes. That way your compressor will not be trying to start when there's a high head pressure during a power event.
