P545NCB22C Lube Oil Control System Electronic 15 Psi Relay Output For Compressor Built In Test Circuit Easy Status Display Pro Grade HVAC Lubrication Controller For Reliable Low Drama Operation
✔️ 15 psi relay output for single unit compressor with test and status
The P545 Series Electronic Lube Oil Control is designed for refrigeration compressors with an oil pump that accepts a single-point differential pressure switch. It continuously monitors lube oil pressure and locks out the compressor if pressure falls below the manufacturer's required net pressure for longer than the recommended time delay. Front-mount LEDs indicate status, and a user-selectable minimum-off time delay helps minimize compressor short cycling. This unit is designed for easy replacement of existing electronic lube oil controls.
✅ Built-in test circuit verifies proper control operation quickly✅ Front-mount LEDs indicate lubrication status continuously
✅ 15 psi relay output for compressor control
✅ Backwards compatibility with existing electronic lube oil controls
✅ Monitors oil pressure via P400 switch to prevent low-pressure run
💡 What is a lube oil control system used for in HVAC compressors? This handy device keeps oil pressure within the required range to protect the compressor and ensure proper lubrication timing.
- It uses a differential pressure switch to monitor net lube oil pressure
- If pressure stays too low for the set delay, the compressor is locked out
- The built in test circuit verifies operation quickly without extra tools
- Front LEDs display lubrication status for easy monitoring
