Belimo TMB24-3-T
35s damper m otor
Torque min. 18 in-lb for control of damper surfaces up to 11 sq ft.
Application:
For On/Off and floating point control of dampers in HVAC systems. Actuator
sizing should be done in accordance with the damper manufacturer’s
specifications.
The actuator is mounted directly to a damper shaft from ¼” up to 5/8” in diameter
by means of its standard universal clamp. Shafts up to ¾” diameter can be
accommodated by an accessory clamp.
Operation:
The actuator is not provided with and does not require any limit switches, but is
electronically protected against overload. The anti-rotation strap supplied with the
actuator will prevent lateral movement.
The TMB series provides 95° of rotation and a visual indicator which indicates
position of the actuator. When reaching the damper or actuator end position, the
actuator automatically stops. The gears can be disengaged with manual release
on the actuator cover.
The TMB24-3... actuators use a sensorless Brushless DC motor, which is
controlled by an Application Specific Integrated Circuit (ASIC). The ASIC
monitors and controls the actuator’s rotation and provides a digital rotation
sensing (DRS) function to prevent damage to the actuator in a stall condition.
Power consumption is reduced in holding mode.
Add on auxiliary switches or feedback potentiometers are easily fastened directly
onto the actuator body for signaling and switching functions.
