P545 Series Electronic Lube Oil Pressure Controls
Monitor net lube oil pressure continuously
If pressure falls below recommended levels, the P545 Series electronic lube oil pressure controls lock out the compressor.
- Used for refrigeration compressors whose oil pump accepts a single-point differential pressure switch
- The P400 switch continuously monitors net lube oil pressure, and the P545 control locks out the compressor if lube oil pressure falls below the manufacturer's recommended net pressure for longer than the recommended lube oil time delay
- Front-mount LEDs indicate lubrication system status, and a user-selectable, minimum-off time delay can be set to minimize compressor short cycling
