Ewc Controls END-10X10-MA15S Nd Motorized Damper 10x10 in

Product Description

The EWC CONTROLS END-10X10-MA15S is a normally closed (ND) motorized damper engineered for zone damper applications in forced-air HVAC systems. Measuring 10 inches by 10 inches with a rectangular profile, this unit operates on 24 volts and features a 15-second motor stroke, providing controlled airflow regulation in zoned ductwork. The bottom-mounted motor connects via a 3-wire configuration and includes an onboard LED indicator light for quick visual status confirmation during commissioning or service. HVAC technicians installing zone control systems will find this damper straightforward to integrate with standard low-voltage zone control boards.

This damper is suited for residential and light commercial forced-air zoning installations where air quality and balanced airflow distribution are the primary design goals. The 10 by 10 inch rectangular size fits standard duct openings of that dimension. The 15-second actuator stroke speed is appropriate for typical zone damper cycling demands. Installation is performed by licensed HVAC technicians as part of a zoned air distribution system, working in conjunction with a compatible zone control panel and low-voltage thermostat wiring.

Key Features

• 10 inches x 10 inches rectangular form factor fits standard duct openings
• 24-volt operation compatible with standard low-voltage zone control systems
• 15-second motor stroke for controlled, damper actuation cycling
• Bottom-mounted motor with 3-wire connection simplifies wiring to zone boards
• Onboard LED indicator light for fast visual status verification
• Normally closed (ND) design defaults to closed position on power loss

Compatibility

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

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler and de-energize the zone control panel before mounting or wiring the damper. Verify duct opening dimensions match the damper face size before securing the unit in place. Follow all applicable mechanical and electrical codes, including NEC low-voltage wiring requirements, when connecting the 3-wire motor leads to the zone control board.
