P66AAB-1

The P66AAB-1 from Johnson Controls is an electronic fan speed controller engineered for demanding environments. It operates effectively within a line voltage range of 208 to 480 VAC and is powered by a 24 Volt AC control voltage, classified under Class 2 standards. This fan speed controller weighs 4.4 lbs and is constructed with a galvanized steel housing, ensuring durability in various applications.

This device features a single input sensor designed for straightforward operation, allowing it to maintain precise control over fan speeds. The P66AAB-1’s operating pressure range is between 190 and 250 psig, which is well-suited for numerous industrial settings. At 240 volts AC, it supports a full load current of 8.0 A, while locked rotor current can reach up to 16.5 A. The controller’s start voltage is set to 10% of the line voltage, facilitating reliable performance during start-up conditions.

Temperature management is essential for electronic components, and this controller is rated for operational temperatures from -40 to 54°C, with a maximum of 66°C at 480 VAC. The storage temperature range is equally impressive, spanning from -40 to 85°C, enabling it to endure varying conditions. Furthermore, the enclosure type is classified as NEMA 1, providing effective protection against non-hazardous environments.

A notable feature of the P66AAB-1 is its pressure connection, which includes a 60-inch copper capillary fitted with a 1/4-inch flare nut and a Schrader valve depressor. These components enhance its versatility and facilitate ease of integration into existing systems.
