Johnson Controls P70AB-12C Pressure Control

The P70AB-12C Pressure Control from Johnson Controls delivers reliable low-pressure control for air conditioning and commercial refrigeration systems. This compact unit excels at condenser fan cycling and head-pressure management, ensuring consistent performance across varying loads.

Operating from 12 inch Mercury (inHg) up to 80 PSI with a maximum line pressure rating of 80 PSI, it provides precise, repeatable control where accuracy matters most. The differential range of 5 to 35 PSI lets you tailor the response to your specific condenser and compressor setup.

Equipped with SPST contacts and versatile electrical ratings, it supports a wide range of installations. Contact configurations include 120 VAC at 24 A (2 HP), 208 VAC at 18.7 A (3 HP), 240 VAC at 17 A (3 HP), and broad AC/DC ranges (120–600 VAC 125 VA; 120–300 VDC 57.5 VA).

With a 1/4 inch flare connection and a sturdy NEMA 1 enclosure, the P70AB-12C is built for reliability in harsh environments. The 36 inch capillary length offers flexible placement in control panels and equipment racks.
