It operates on auto-sense voltage technology, accepting 120, 208, and 240 VAC single-phase 60 Hz input without manual adjustment. The unit includes a normally closed relay output rated at 24 VAC and 2 amps for low-voltage control circuit integration. Built-in LED indicators give technicians real-time status feedback for fast field diagnostics. The device is UL listed and compliant with ANSI\/UL 1449 3rd edition and AHRI Standard 110-1012 Range B2 for voltage drop protection.\u003c\/p\u003e\n\u003cp\u003eThe CD1-024R is suited for residential and light commercial applications where compressor protection is required. It can be installed inside a condensing unit or mounted on an outdoor compressor. Typical applications include central air conditioner and heat pump systems where power quality issues such as brownouts, voltage surges, or rapid short cycling pose a risk to compressor longevity and control board reliability. Licensed HVAC technicians install this device as part of routine system protection or as a retrofit on existing equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAuto-sense voltage technology accepts 120, 208, and 240 VAC without manual configuration\u003c\/li\u003e\n  \u003cli\u003eType 2 SPD surge protection with a voltage protection rating of 700 V line-to-neutral\/ground and 1200 V line-to-line\u003c\/li\u003e\n  \u003cli\u003eNominal discharge rating of 10 kA\u003c\/li\u003e\n  \u003cli\u003eNormally closed relay output: 2 amps at 24 VAC isolated contact for low-voltage control integration\u003c\/li\u003e\n  \u003cli\u003eLED indicators for real-time system status and simplified field troubleshooting\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI\/UL 1449 3rd edition and AHRI Standard 110-1012 Range B2\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style retrofit protector for residential and light commercial central air conditioner and heat pump condensing units operating on single-phase 120, 208, or 240 VAC 60 Hz power.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician.
