Description

DCL small size modulating type electric actuators are widely used in combustion system, especially for burners, both in China and USA. Actuators are installed on the fuel intake duct/pipe to control flame or installed on ventilation valve to control temperature. Since the boiler is always in very high temperature and always has strong electromagnetic interference to surroundings, so the actuator must suffer very severe applications.

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.
