Description

The DCL-H series actuators motorized by 3 phase AC power. Actuators can have both clockwise (CW) and counter-clockwise (CCW) control inputs. One drives the actuator to its open, the other to its close position. If there is no signal (Null point) on either input the actuator simply stays in its last position. Actuator is easy to install using standard ISO5211 multi-flange mounting and double square drive.

All series of DCL control packs have passed 4000V EFT(Electrical Fast Transition), 4000V ESD (Electrostatic Discharge)and 2500V Surge test and Radiation test, and 85℃/85% humidity test, which ensure actuator can keep high accuracy drive in combustion system. DCL has built a comprehensive test lab for 5 years to do above tests constantly to ensure quality stability. Actuators are also tested and certified by CSA and complied to UL/CE/RoHS 3.0 standard.
