Thermal actuator Application The thermal actuator is suitable to be mounted on all manifolds, thermostatic valve bodies and three-way valves. This actuator is maintenance-free and has been devised to be fitted to controllers with a 2-point exit,….. Function Version normally closed (NC) When applying the operating voltage the expansion system of this actuator will be heated up. After passing the dead time a uniform opening procedure will follow. When the voltage supply will be cut off, this actuator will automatically close after passing the dead time due to cooling of the expansion system. Version normally opened (NO) When applying the operating voltage the expansion system of this actuator will be heated up. After passing the dead time a uniform closing procedure wil follow. When the voltage supply will be cut off , this actuator will automatically open after passing the dead time due to cooling offthe expansion system. Note:In case of any functional test,, please be aware of the dead time behaviour off this actuator and duly take this into consideration ! The opening and closing times will depend upon the ambient temperature Technical Date Operating voltage: 230V AC/DC (+10% / -15%) -Frequency 0 up to 60Hz Power consumption: 3 W (VA) in continuous operation -Starting phase 90W (VA) Version: NC and NO Closing and Opening times: approx. 3min Overvoltage protection: Varistor Approvals: CE Type of protection : acc.
