EWC Controls MA-15S Damper Motor
The EWC Controls MA-15S is a high-torque, 24V replacement motor designed specifically for EWC motorized dampers requiring a rapid 15-second stroke cycle. This synchronous motor is engineered for high-cycle reliability in residential and light commercial zoning systems, providing precise airflow control to maintain static pressure balance. Unlike standard 45 or 60-second actuators, the MA-15S damper actuator features a shortened gear train for accelerated operation, making it the primary replacement motor for EWC ND and URD dampers. When performing a field replacement, technicians should verify the three-wire terminal configuration (PO/PC) to ensure correct integration with the Ultra-Zone control board. The low-voltage 15-second motor is built with rugged internal gearing to prevent stripping under high static loads, ensuring the damper blade reaches full closure or maximum aperture without lag.
Key Benefits for the Contractor- Direct OEM Compatibility: Specifically designed as a drop-in replacement for EWC MA-15S units, ensuring proper shaft alignment and mounting hole synchronization.
- Rapid Response Time: The 15-second travel time reduces dwell periods, allowing the zoning system to reach setpoint temperatures more efficiently.
- High Torque Output: Provides sufficient force to overcome dust accumulation and minor debris within the HVAC damper housing.
- Three-Wire Operation: Simple wiring interface for Power Open (PO) and Power Close (PC) functionality, compatible with most legacy and modern EWC zone panels.
- Industrial Build Quality: Features a durable housing and heavy-duty gear set designed for the high-frequency demands of multi-zone forced air systems.
Is the MA-15S compatible with other damper brands?
This motor is specifically calibrated for the mounting footprint and shaft requirements of EWC Controls dampers. While it may share electrical similarities with other 24V actuators, it is intended primarily for zoning system repair on EWC hardware.
What causes a 15-second motor to fail prematurely?
Premature failure is often caused by over-tightened damper blades or excessive static pressure that forces the motor to stall. Always check for mechanical obstructions in the damper assembly before installing a new synchronous actuator.
Can I use a 2-wire setup with this motor?
No, the MA-15S requires a 3-wire connection to control both the opening and closing cycles. Ensure your zone board or thermostat relay provides a common and two switched leads.
