Functional Devices PSH200A-LVC Power Supply
For contractors managing complex commercial automation, the Functional Devices PSH200A-LVC is a professional-grade 200VA power supply designed to streamline multi-zone 24VAC distribution. This unit features five independent 40VA Class 2 outputs, each protected by an integrated circuit breaker and equipped with LED status indicators for rapid field diagnostics. The multi-tap primary transformer accepts 120V, 208V, 240V, 277V, 347V, and 480V inputs, eliminating the need for separate transformers across different line voltages. Constructed with a separate high/low voltage wiring compartment within a NEMA 1 metal enclosure, it ensures clean cable management and code compliance. The finger-safe terminals and sub-panel mounting design make it a reliable choice for VAV controllers, damper actuators, and BAS peripherals. By consolidating multiple isolated 24VAC power sources into a single UL Listed enclosure, technicians can significantly reduce installation footprint and labor time while maintaining rigorous electrical safety standards on site.
Key Benefits
- Universal Input Compatibility: Supports a broad range of primary voltages from 120V to 480V for maximum job site versatility.
- Isolated Power Distribution: Five discrete 40VA outputs prevent total system failure by isolating downstream shorts.
- Enhanced Safety separation: Dedicated internal compartments isolate high-voltage mains from low-voltage control wiring.
- Field-Serviceable Design: Built-in on/off switches and individual breakers allow for safe localized maintenance.
- Status Recognition: External LED indicators provide immediate visual confirmation of active 24VAC power status.
Common Questions
Can I combine the 40VA outputs for a single large load?
No. These are isolated Class 2 outputs designed to be used independently. Paralleling the secondaries is not recommended as it may bypass the Class 2 current-limiting safety features.
What is the maximum wire gauge supported by the terminals?
The high-voltage primary terminals accept 8-18 AWG wire, while the low-voltage secondary terminals are designed for 12-26 AWG wire.
Does this unit require an external fuse?
The PSH200A-LVC includes an integrated circuit breaker and secondary current limiting to protect the transformer and downstream devices, though local codes may still require a dedicated primary branch circuit breaker.
