Belimo LMB24-HM

SKU: CS922942MPN: LMB24-HM

Damper Actuator, 45 in-lb [5 Nm], Non fail-safe, AC/DC 24 V, On/Off

Product Details

The –HM series of actuators are intended for retrofi t of Belimo LM24-M and LM24-10P-M actuators used in OEM VAV controllers that have reached the end of their service life. These actuators are specifically designed as a drop-in replacement without any alteration to the existing VAV system.

The actuator is mounted in the same location as the current actuator and mates directly to the damper shaft by means of the standard universal clamp. The existing 5 pin Molex connector plugs directly into the replacement actuator and 24 VAC/DC power is applied via a separate plenum rated power cable.

The -HM series utilize Belimo brushless Halomo motor technology. This motor drive technology monitors and controls the actuator position based on an input signal from the VAV controller. When reaching an end position, the actuator automatically stops and reports this condition to the VAV controller. Power consumption is reduced when in holding mode.
