Functional Devices PSH100AW Power Supply
For contractors requiring a reliable, "all-in-one" solution for building automation and control circuits, the Functional Devices PSH100AW is a professional-grade 100VA power supply. This unit simplifies field installations by integrating a high-efficiency split-bobbin transformer within a rugged NEMA 1 metal enclosure. Designed specifically for 120 VAC to 24 VAC step-down applications, the PSH100AW is UL Class 2 listed, ensuring it meets strict safety and current-limiting standards for low-voltage HVAC/R and BAS networks. The "W" designation signifies a model equipped with pre-wired secondary leads, reducing termination time during panel builds. To simplify troubleshooting and prevent downstream damage, the unit features an integrated 24 VAC circuit breaker and a visible LED indicator to confirm active power status at a glance.
Commonly Asked Questions:
- How do I troubleshoot a lack of 24 VAC output? Check the integrated 24 VAC circuit breaker first. Use a voltmeter to verify 120 VAC input across the primary black and white wires. If input is present but the LED is off and the breaker hasn't tripped, verify the secondary load doesn't exceed the 100VA rating.
- Can I mount the PSH100AW inside an existing hub? Yes, this enclosed transformer is intended for surface mounting or placement within a larger control cabinet to provide dedicated 24 volt power to controllers and peripherals.
- What is the maximum ambient operating temperature? This unit is rated for stable performance up to 40° C (104° F). In high-heat environments, ensure proper ventilation to prevent thermal output derating.
Key Benefits for Technicians:
- Efficient Field Deployment: Features a split-bobbin transformer design that offers superior isolation and Class 2 compliance for safe, reliable power distribution.
- Built-In Protection: Includes an integrated manual reset circuit breaker and ON/OFF switch, eliminating the need for external fuse blocks in the 24V circuit.
- Ready for Installation: The enclosed 100VA unit comes with internal wiring and a 3-foot extension cord for rapid 120V connectivity in mechanical rooms.
- Visual Diagnostics: A prominent red LED provides immediate confirmation of secondary voltage, streamlining maintenance and system checkouts.
