AS Series Spring Return Electric Actuator

AS Series Spring Return Electric Actuator

Indelac AS Series spring return electric actuator is a robust heavy-duty actuator recommended for systems requiring as many as 25 cycles per day. Like model ES2, the operating cycle life of the actuator is drastically affected by the model of operation. Power to open and close will provide for years of reliable performance. Spring end torque ranges from 400 to 1000 lb-in with a closing speed of 3 sec./90 degrees upon loss of power.

Standard equipment includes 115Vac-1ph Continuous duty motor with thermal overload protection, set to fail closed (CW rotation) upon loss of power, two limit switches, power on brake, stainless steel fasteners, 300 series stainless steel output drive, polyester powder coating.
