FAN SPEED CTRL 190-250PSI 5FT

The Fan Speed Control, P66AAB-1 Switch, 190-250psi, 5ft leads allows you to control the speed of your motor. This is a 12V switch.

This electronic fan speed control is a 5 ft. instrument cable that is permanently attached to a 190-250 PSI electronic pressure switch and then uses a bicolor LED indicator to display the status of the system.

The Johnson Controls Electronic Fan Speed Control is a thermally protected variable-speed fan speed controller that controls single-phase fans from 190 through 250 psi. The controller features an LED indicator for quick status checks.

An Electromagnetic Flow Control (EMFC) is built into the fan speed controller to prevent pump cavitation. This fan has been designed to provide precise control of the temperature of a heat transfer fluid, either at a constant temperature or with user defined rising and falling set points. This fan provides an accurate means of measuring the temperature in a heat transfer fluid, which is commonly used to cool computer components, such as motherboards, power supplies, graphic cards or other devices that generate a large amount of heat.

An electronic fan speed control is a thermostatic controller used to reduce fluctuations in temperature and thus energy consumption by regulating the supply of hot air to an air conditioning (heating) system. It achieves this by ensuring that the fan is only energized at times when the system needs additional hot air. The fan controls supplemental cooling requirements that vary depending upon system conditions and refrigerant flow.

The P66AAB1 is a low-voltage, electronic Pressure Control used to provide automatic pressure control to fan coil units in commercial refrigeration systems. The P66AAB1 has top mounted quick-connect terminals for direct wiring connection to fan coils. A primary power supply (AC) of 115VAC 50/60Hz (200VA) is applied to the contacts of the pressure control. The pressure control senses the pressure in the air cooled coil and responds by controlling the AC voltage across terminals 3 and 6.

The P66 is a low side-force controller with high pressure sensor and high flow alarm capability. The controller has a unique patented safety system that provides up to 3 safety functions: voltage limit, over-current protection and flowrate alarm.
