The A250-MOC is a 24VAC power open/dose or modulating actuator for use with zoning dampers and provides 250 in-oz of torque. The actuator can operate either open/dose or modulating.

Used with the eWD2 and eWD3 panels, the A250-MOC can be used for bypass excess air flow by opening just enough to maintain the minimum air flow and eliminate the need for bypass ducts and a barometric damper.

The A250-MOCT is supplied with mounting tabs and mechanically attached to the damper on standoffs.
