SMART START ASSIST
SM series are available with the Smart Start Assist
device as either a factory installed option or a field
installed accessory.
This device reduces starting (in-rush) current for
compressors by 45% to 65%. This reduction in
starting current can eliminate or greatly reduce
“light flickering” during compressor starts and can
reduce the required size of back-up transformers.
the adaptive technology of the device can also
extend compressor life by providing smoother,
lower currents starts and by protecting the
compressor from transient over voltage and under
voltage after ramp up.
The smart Start is designed for single phase scroll
compressors and can also optimize algorithms for
high pressure starts.
