Enviro-tec PE-10-0048 Transformer

The Enviro-tec PE-10-0048 Transformer is a high-reliability OEM component designed to provide precise 24VAC control power for commercial HVAC terminal units. Engineered for single-phase operation, this 120v/24v 50Va transformer facilitates stable voltage stepping to ensure consistent performance of DDC controllers, actuators, and sensor arrays. As a veteran technician knows, maintaining the integrity of the control circuit is paramount; the PE-10-0048 is the direct replacement for PE-10-2105, offering a seamless mechanical and electrical match for aging Enviro-tec VAV boxes, blower coils, and fan coil units. By utilizing a genuine Enviro-tec replacement part, contractors ensure full compatibility with the FlowStar™ air-measuring systems and existing wiring harnesses. This HVAC control transformer is built to handle the inductive loads common in zone-control air conditioning, providing a robust 50VA capacity that prevents voltage sag during high-demand cycles. Field-verified for 50/60Hz applications, it serves as a critical step-down transformer for maintaining accurate airflow and zone comfort in demanding commercial environments.

• OEM Compatibility: Specifically engineered to match the electrical characteristics and footprint of Enviro-tec terminal units.
• High Power Capacity: The 50VA rating provides ample overhead for powering multiple peripherals, including damper actuators and reheat valves.
• Direct Supercession: Eliminates field-modification time by serving as the exact drop-in replacement for the discontinued PE-10-2105.
• Reliable Voltage Stability: Ensures the 24VAC secondary remains consistent, protecting sensitive DDC electronics from fluctuating line voltage.

Is this transformer compatible with older PE-10-2105 models?
Yes, the PE-10-0048 is the official manufacturer-designated replacement for the PE-10-2105. It maintains the same primary 120V input and 24V output specifications required for legacy Enviro-tec equipment.

What happens if I use an aftermarket transformer with a lower VA rating?
Using a transformer with less than 50VA can lead to overheating and premature failure, especially when the VAV controller triggers simultaneous actuator movements. This OEM part ensures the circuit has the required 50VA capacity.

Can this be used on 208V or 277V systems?
This specific model is designed for a 120V primary input. For multi-tap or higher voltage requirements, verify the primary feed before installation to ensure match with this 120V/24V unit.
