Enviro-tec PE-10-7105 Transformer

The Enviro-tec PE-10-7105 Transformer is a heavy-duty 480V to 24V control transformer engineered for high-demand commercial HVACR applications. Rated at 50VA, this unit is designed to provide stable 24VAC secondary voltage for powering critical control components, including actuators, relays, and digital controllers in air handlers and VAV terminals. As a genuine Enviro-tec OEM part, it ensures precise electrical synchronization and secondary circuit protection that many aftermarket multi-tap alternatives fail to provide. The foot-mount transformer configuration features a rugged base plate for secure installation inside electrical cabinets, while the welded laminations minimize audible hum and vibration. With 50/60Hz compatibility, this 480V primary transformer is built to withstand the thermal stresses of industrial voltage regulation. Whether you are performing a field replacement or a system upgrade, the PE-10-7105 offers the reliability required for continuous-duty operation in high-voltage environments.

• Precise Voltage Conversion: Steps down 480V primary power to 24V secondary output, ideal for sensitive HVACR control circuits.
• OEM Standards: Guaranteed direct-fit compatibility for Enviro-tec air handlers, blower coils, and VAV terminal units.
• Durable Foot-Mount Design: Rugged base plate provides a stable mechanical connection in high-vibration equipment areas.
• Thermal Efficiency: Engineered for low heat rise to maintain performance in enclosed, high-temperature control cabinets.
• Quiet Operation: High-quality core laminations reduce electrical noise and resonance in commercial environments.

What happens if I use a 40VA transformer instead of this 50VA unit?
Using an undersized transformer can lead to excessive heat and eventual coil failure. The 50VA rating of the PE-10-7105 provides the necessary overhead for simultaneous operation of multiple 24V control loads.

Is the PE-10-7105 compatible with 50Hz and 60Hz systems?
Yes, this transformer is designed for 50/60Hz operation, making it suitable for a wide range of industrial power grids and localized equipment specifications.

How do I confirm this is the right replacement for my air handler?
Check the nameplate on your existing unit for the PE-10-7105 or PE107105 part number. This genuine OEM part is specifically calibrated for Enviro-tec's primary voltage requirements and foot-mount footprint.
