Features: SPC series pressure controllers are used for high and low pressure limit control of refrigeration equipment or automatic system air conditioning equipment. Apply to air, liquid and other non - corrosive media. Standard mounting bracket is provided for easy installation. The SPDT switch ensures reliable contact switching. The pressure bellows of the standard model are phosphor copper bellows and the pressure connection is made of brass. The bellows and the pressure connection for the ammonia refrigerant model are made of stainless steel Specification: Non-inductive current :20A, full load current :15A, and instantaneous current :72A;When rated voltage is 125VAC, Non-inductive current: 10A, full load current: 8A, and instantaneous current: 72A;When rated voltage is 250VAC Thread: G thread Pressure regulating range (bar) : -0.5 (Min) ~2 (Max) Differential pressure adjustment range (bar) : 0.2 (Min) ~0.7 (Max) Maximum air tightness test (bar) : 16.5 Power supply voltage: 24V~380V Life of micro switch: 100,000 times Weight: Approx.397g/14oz Refrigerant: air, liquid and other non - corrosive media Scope of application: control the pressure difference between liquid pipe and return pipe in water and oil series (air conditioning and other specific places) Package list: 1 x Pressure Controller 1 x Install bracket 1 x instructions 4 x Screw
