Technical Specifications Condition New/Never Used Surplus Brand Alco-Emerson Part Number PS1-X5A Type Adjustable Refrigeration Pressure Switch Reset Type Auto Reset Pressure Range 6–31 bar (90–450 psig) Operating Temperature –50°C to +70°C Electrical Rating 24 FLA / 144 LRA Voltage 115–230 VAC Application Refrigeration, HVAC, compressor protection Function High/Low pressure safety control Weight 0.68 lbs Information About PS1-X5A The PS1-X5A is designed as part of Emerson’s trusted line of refrigeration pressure controls, offering dependable performance for compressors, condensers, and general refrigeration safety circuits. The device provides an adjustable pressure range from 6–31 bar (90–450 psig), making it adaptable to a broad selection of refrigerants and system requirements. Auto-reset functionality enables the switch to re-engage automatically once system pressure returns to safe limits, reducing downtime and maintaining operational continuity. Its electrical capacity—24 FLA / 144 LRA at 115–230 VAC—supports direct control of typical refrigeration loads. Designed to withstand harsh conditions, the PS1-X5A operates within a temperature range of –50 to +70°C, making it suitable for low-temperature refrigeration, freezers, and outdoor HVAC units. Key Features: Wide Adjustable Pressure Range: Supports 6–31 bar (90–450 psig) for flexible refrigeration system integration. Auto-Reset Function: Restores operation automatically once pressure normalizes, reducing manual intervention. High Electrical Rating: Handles 24 FLA / 144 LRA at 115–230 VAC for direct compressor and motor control. Rugged Operating Temperature Range: Performs reliably from –50°C to +70°C in demanding refrigeration environments. Versatile Refrigeration Application: Suitable for HVAC systems, walk-in coolers, freezers, compressors, and condensing units. Durable Construction: Built for long-term stability under vibration, moisture, and thermal stress. Compact Form Factor: Ideal for integration into control panels or mounted directly near refrigeration components. Precise Pressure Regulation: Ensures safe system pressure levels to protect compressors from overload. Reliable Performance: Designed for continuous-duty commercial refrigeration systems. Universal Voltage Compatibility: Works with 115–230 VAC systems without additional modifications. The PS1-X5A delivers the reliability and precision required for maintaining safe and efficient pressure control in refrigeration and HVAC systems.
