Direct Coupled Damper Actuators Flat Pack Series

The flat pack series is UL/cUL listed and CE compliant. It is also NEMA 4 (IEC IP56) compliant when used with customer supplied water tight conduit connectors. Units are available to operate from 24Vac (class 2) and 120Vac and 240Vac (class 1). The Flat Pack Series are direct-coupled actuators used for damper control applications. They are available in spring return and non-spring return models, with two-position control. They may be specified to be either analog proportional control action or floating proportional control action.

 

Flat pack series actuators are mounted directly onto the damper shaft by means of dual mounting clips. The anti-rotation bracket supplied with the actuator prevents lateral movement of the actuator on the shaft. The damper actuator is not provided with and does not require any limiting switches. It is electrically protected against overloading. The angle of rotation is electrically limited to 93 ± 1°. When reaching the damper or actuator end position, the motor stops automatically. The position of the actuator is indicated by means of an integral scale reading 0º to 95°.

 

EA02-P Series
This actuator is available only in a spring return version with two position control, two wire SPST or triac (500mA rated). It is rated at 150 in-lbs torque, 145 second timing and operates from 24, 120 or 240 Vac power.

 

EA01-A Series, EA02-A Series
These actuators are available in both non-spring return (01) and spring return (02) versions. Both feature analog proportional control action and operate from 24, 120 or 240Vac power. The 01-A versions are rated at 300 in-lbs and 145 seconds travel time. The 02-A series are rated at 150 in-lbs and 145 seconds travel time.

 

Manual Override – Non-Spring Actuator
An accessory crank is provided with each non-spring return actuator so it can be manually positioned to ease installation or for emergency positioning. To engage manual override, insert the crank in the drive hole, press and hold inward while turning. Approximately 114 revolutions rotate the actuator its full 93°. The actuator automatically disengages manual override when power is applied to the drive open or drive close connection. Avoid manually repositioning the actuator beyond its adjustable travel limit setting.

 

Caution: Use manual override only when actuator drive motor is not powered. Engaging the manual override when the actuator is powered will cause damage to the gears. Using power tools to adjust the override will cause damage to the gears.
