Enviro-tec PE-27-0042 Controller

The Enviro-tec PE-27-0042 Controller serves as the direct OEM replacement for the ETFC120-10, providing precise control for SCR fan motor applications in VAV terminals and blower coils. Engineered for 120V input, this solid-state speed controller manages motors ranging from 1/4 HP to 3/4 HP, ensuring stable performance across varying static pressures. It functions as a proportional controller, translating a 0-10VDC or 2-10VDC signal into a specific voltage output to maintain optimal airflow. For technicians replacing the legacy ETFC120-10 SCR controller, this unit offers a seamless mechanical fit and verified electrical compatibility. The PE-27-0042 is essential for systems requiring manual or automated blower speed adjustment to balance HVAC zones effectively. Its rugged construction facilitates reliable operation in demanding commercial environments, preventing common issues like motor humming or erratic speed cycling found in generic alternatives.

• Direct OEM Fit: Drop-in replacement for the discontinued ETFC120-10, reducing field modification time.
• Enhanced Motor Range: Rated for 1/4 HP through 3/4 HP motors, covering the most common commercial air handler sizes.
• Precise Signal Response: High-resolution 0-10VDC control allows for fine-tuning of CFM delivery to meet design specifications.
• Reliable Heat Dissipation: Built-in heatsink design manages thermal loads during continuous operation.
• Universal Command: Compatible with most standard BAS controllers and VAV actuators.

Is the PE-27-0042 compatible with older Enviro-tec VAV boxes?
Yes, this controller is the designated update for the legacy ETFC120-10 series commonly found in older VAV fan-powered terminals and parallel units.

What input signal does this SCR controller require?
This unit is designed to accept a 0-10VDC control signal from a thermostat or DDC controller to vary the motor speed proportionally.

Can this unit handle 1/2 HP motors?
Exactly. The PE-27-0042 is rated for 1/4 to 3/4 HP, making it ideal for 1/2 HP motor applications at 120V.
