Dual Pressure controls H/L Model: P830HME
 
Pressure controls are pressure-activated switches, with a basic function to make or
break an electrical circuit which in turn controls a solenoid coil, a contractor or some other
functioning part of the system. The set point at which a control closes a contact and makes
a circuit is called the cut-in point.The point at which the control opens the switch and breaks
the circuit is called the cut-pit point. The difference between the cut-in and cut-out point is
known as the differential.
 
*P830 series pressure controls can protect compressors in refrigeration and air-condition plant, and keep
them from over-low pressure or over-high suction pressure.
*P830 series pressure controls can start and stop refrigeration compressors and fans of air condensers.      *P830 series pressure controls can be used not only in fluoride refrigeration but also in air and liquid.           *P830 series pressure controls are fitted with a single pole double throw (SPDT) changeover switch.
 
The position of the switch is determined by the pressure control setting and the pressure at the
connector.
