All order information of ESM-3712-CN Cooling Controller are given on the table at left. User may form appropriate device configuration from information and codes that at the table and convert it to the ordering codes.

Firstly, supply voltage then other specifications must be determined. Please fill the order code blanks according to your needs.

Please contact us, if your needs are out of the standards.

Note-1: If input type is selected PTC or NTC (BC= 12, 18), Temperature sensor is given with the device. For this reason, if input type is selected as PTC, sensor type (V = 0,1 or 2) or if input type is selected as NTC, sensor type (V =0,3 or 4) must be declared in ordering information.
