Functional Devices TR150VA001 Transformer

When you need to power multiple 24Vac control circuits from a single source, the Functional Devices TR150VA001 Transformer is the heavy-duty solution. This 150VA-rated power supply is designed for professional HVACR and building automation applications where lower-capacity transformers fall short. Built with a 120Vac primary voltage input, it provides a stable 24Vac secondary voltage output, optimized for powering large banks of relays, temperature control systems, or high-draw magnetic switches. The split-bobbin construction ensures reliable isolation between the primary and secondary windings, maintaining high efficiency across its -30 to 140 F operating range.

Installation flexibility is a priority for field technicians, and the TR150VA001 delivers with both foot and single threaded hub mount options. This allows for secure attachment to junction boxes or direct mounting within control panels. To protect your low-voltage peripherals from electrical faults, this unit features an integral circuit breaker over current protection, allowing for quick resets without the need for traditional fuse replacements. With color-coded 8-inch wire leads and UL5085-2 listing, this transformer simplifies wiring while meeting strict safety standards for general-purpose industrial use.

• High-Capacity 150VA Output: Delivers enough power for complex building automation systems and multiple HVAC devices.
• Integrated Over Current Protection: Features a manual reset circuit breaker to prevent secondary circuit damage and minimize downtime.
• Dual-Mount Design: Provides both a threaded 1/2" NPT hub and a foot mount for versatile installation in panels or boxes.
• Industrial Build Quality: Utilizes split-bobbin construction to ensure electrical isolation and long-term durability in harsh environments.

• Can this transformer be used for Class 2 applications? While the TR series includes Class 2 models, the 150VA rating of the TR150VA001 exceeds the power limits for Class 2 certification; it is rated as a UL Listed General Purpose transformer.
• What is the purpose of the circuit breaker? It protects the transformer and connected 24V components from short circuits or overload conditions by interrupting the circuit.
• Is it compatible with 50Hz and 60Hz systems? Yes, this unit is engineered to operate on both 50Hz and 60Hz frequencies, making it suitable for a wide range of power standards.
