Ewc Controls END-MA15S-10X12 Nd Motorized Damper 10x12in

Product Description

The EWC CONTROLS END-MA15S-10X12 is a rectangular ND motorized damper designed for zone control and air quality applications in forced-air HVAC systems. The damper measures 10 inches by 12 inches and operates on 24 volts, making it compatible with standard low-voltage zone control wiring. A 15-second motor provides smooth, controlled blade actuation. An onboard LED indicator allows technicians to confirm motor operation at a glance. This unit is installed by licensed HVAC technicians in residential and light commercial duct systems where zone dampers regulate airflow to individual spaces.

This damper is suited for rectangular duct installations where zone control is required to balance airflow or improve air quality. The bottom motor mount configuration allows installation in duct runs where overhead access is limited. The 3-wire motor connection supports standard open-close or spring-return control sequences typical of HVAC zone control boards. It fits into forced-air distribution systems where multiple zones are independently controlled by a zone panel or thermostat-driven controller.

Key Features

• 24-volt low-voltage operation compatible with standard zone control boards
• 15-second motor actuation speed for smooth damper blade transition
• LED indicator light for quick visual confirmation of motor status
• Bottom motor mount for flexible duct installation orientations
• 3-wire motor connection supports standard zone control wiring schemes
• Rectangular shape fits 10 inch by 12 inch duct openings directly

Compatibility

Designed as an OEM-style replacement or new-installation motorized damper for rectangular forced-air duct systems requiring 24-volt zone control in air quality applications.

Installation Notes

Installation should be performed by a licensed HVAC technician. De-energize the air handler and zone control panel before wiring or mounting the damper. Secure the damper in the duct section per the manufacturer orientation markings, ensuring the bottom motor mount is accessible for wiring and future service. Wiring should comply with applicable NEC requirements for low-voltage HVAC control circuits.
