Compressor Defender™
Surge/Brownout/Short Cycle Protective Device
The Compressor Defender protects compressors (scroll &
reciprocating) and the electronics inside an air conditioner from
under/over voltage conditions, surge events, and system short cycling.
It also protects heat pumps, light commercial packaged rooftop units,
and mini-splits.
Features
• Surge, brownout and short cycle protection with 120, 208 and
240 VAC loads
• Short cycle delay helps extend compressor life
• LED indicators provide real-time status updates for quick and
easy troubleshooting
• For use inside condensing units or externally on disconnects
• Complies with ANSI/AHRI Standard 110-2012 Range B² for voltage
drop protection
• Auto-sense voltage technology 120-240 VAC universal input voltage
• Meets ANSI/UL 1449 3rd edition requirements
