Schneider Electric MD10SR-TS Spring Return Damper Actuator
Schneider Electric MD10SR-TS is a 10 Nm fail-safe HVAC damper actuator with mechanical spring return, 2-position / 3-wire floating control, 24–240 VAC / 24–125 VDC supply and IP54 protection.
Schneider Electric MD10SR-TS provides fail-safe airflow control with two integrated SPDT auxiliary switches in ventilation and air-conditioning systems. The motor drives the damper during normal operation, while the mechanical spring moves it to the selected safety position after power loss. Its 10 Nm torque is intended for dampers of approximately 2 m², subject to damper construction and installation conditions.
