Heavy-Duty Construction: Built with 3/8-16 UNC threads to provide a high-torque connection that resists vibration
Applying 24V will not provide sufficient torque to actuate the motor
Simplifies the pneumatic valve assembly process during maintenance or control system upgrades
Most failures are due to restricted airflow (dirty filters or blocked coils) or mechanical vibration causing the element to contact the frame
which would restrict the refrigerant charge and cause control failure
Functional Devices PSH100A Power Supply Els PW 17895 Heavy-Duty Construction: Built with 3/8-16The Functional Devices PSH100A is a robust 100VA enclosed power supply engineered for demanding building automation and HVAC control applications. Designed to step down 120 VAC to 24 VAC, this Class 2 transformer provides consistent power for controllers, actuators, and sensors requiring precise voltage stability. Housed in a NEMA 1 rated metal enclosure, the PSH100A features a built in circuit breaker that eliminates the need for external fuse
