Functional Devices PSH75A75AB10 Power Supply
The Functional Devices PSH75A75AB10 is a heavy-duty, enclosed dual 75VA power supply designed for critical building automation and HVAC control systems. This UL Class 2 power supply features two independent split-bobbin transformers, each providing a reliable 24 VAC output to ensure isolated power delivery for sensitive controllers and field devices. Engineered with a multi-tap primary input, this unit supports 480, 277, 240, 208, and 120 VAC, making it highly versatile for various industrial line voltages without requiring additional step-down hardware.
For enhanced circuit protection and ease of maintenance, the PSH75A75AB10 includes a dedicated 10A main circuit breaker that serves as the master disconnect for the entire unit, including the internal transformers and auxiliary outputs. Each 24 VAC secondary is equipped with its own individual on/off switch and integral breaker, allowing technicians to isolate specific sub-circuits for troubleshooting without powering down the entire panel. The rugged metal enclosure includes a high-voltage wiring compartment and an external terminal strip for efficient field termination, while LED status indicators provide immediate visual confirmation of active 24V power presence.
Key Benefits- Multi-Tap Versatility: Supports 120/208/240/277/480 VAC primary inputs for maximum site compatibility.
- Dual Isolated Outputs: Two independent 75VA transformers provide clean 24 VAC power, totaling 150VA capacity.
- Comprehensive Protection: Integrated 10A main master breaker and individual secondary breakers ensure high-level overcurrent safety.
- Technician-Friendly Design: Features manual on/off switches for each transformer and clear LED diagnostics.
- Code Compliance: UL Class 2, UL916, and C-UL listed, ensuring safety in commercial and industrial automation environments.
Can the PSH75A75AB10 be used on 480V industrial circuits?
Yes, the multi-tap primary winding is designed to handle 480 VAC directly, along with several other standard line voltages, allowing for simple integration into most motor control centers or HVAC panels.
What is the purpose of the 10A main breaker on this power supply?
The 10A main breaker acts as a primary safety disconnect and overcurrent protection for the entire assembly. It ensures that the internal transformers and any auxiliary equipment are protected against upstream electrical faults.
Are the 24V outputs isolated from each other?
Yes, because this unit utilizes two separate transformers, the secondary circuits are isolated, preventing electrical noise or fault conditions in one loop from affecting the other.
