Functional Devices PSH300A-LVC Power Supply
For contractors managing multi-voltage sites, the Functional Devices PSH300A-LVC is a specialized 300VA power supply designed to streamline 24VAC control circuit integration. This unit functions as a versatile multi-voltage transformer, accepting primary inputs of 120, 240, 277, or 480 VAC, making it an essential component for building automation systems (BAS) and complex HVACR installations. The PSH300A-LVC features three independent 100VA Class 2 outputs, each protected by an dedicated integral circuit breaker and equipped with a convenient on/off switch and LED status indicator for rapid field diagnostics. Its NEMA 1 metal enclosure is engineered with a high/low voltage separation barrier, ensuring code-compliant wiring within separate compartments to mitigate interference and enhance safety. Whether powering VAV boxes or industrial controllers, this enclosed power supply provides reliable step-down conversion with finger-safe terminals, reducing installation time and ensuring stable power delivery across demanding commercial environments.
Key Benefits- Multi-Tap Input Versatility: Supports 120/240/277/480 VAC primary leads for universal compatibility on any job site.
- Triple Class 2 Outputs: Three isolated 100VA, 24VAC secondaries prevent total system failure by segmenting control loads.
- High/Low Voltage Separation: Pre-installed internal barrier allows for safe, organized wiring in compliance with electrical codes.
- Integrated Diagnostics: Dedicated 4A breakers and LED indicators for each output allow for immediate identification of short circuits.
- Rugged Enclosure: Heavy-duty NEMA 1 metal housing with multiple knockouts facilitates clean conduit attachment and panel mounting.
How do the separate wiring compartments improve installation safety?
The internal metal divider physically isolates high-voltage primary connections from low-voltage secondary terminals, preventing accidental contact and reducing the risk of induction noise in sensitive control circuits.
Can I use all three 100VA outputs simultaneously?
Yes, the PSH300A-LVC is designed to provide a full 300VA total capacity, split across three 100VA lines, each independently switched and fused for maximum reliability.
Is this power supply suitable for plenum-rated spaces?
When installed with the appropriate covers and conduit fittings, the metal enclosure maintains the integrity of the installation; however, always verify local code requirements for specific plenum applications.
