Potentiometer for controlling EC fans. Output voltage on ST EC 10 and ST EC 230 continuously adjustable between 0 - 10 V using a rotary knob. ST EC 3 allows the output voltage to be regulated in 3 levels: Level 1 = 3 - 7 V adjustable, Level 2 = 5 - 9 V adjustable, Level 3 = 10 V. The potentiometer can be installed in a flush-mounted box without housing (IP 44) or surface-mounted with the housing (IP 54). An additional switching contact on the ST EC 010 enables, for example, the connection of a controller release. ST EC 230 for connection to a power supply of 230 V. ST EC 010 for connection to a power supply of 10 V. ST EC 3 for connection to a power supply of 10 - 15 V.
