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.
