Single phase

Split-type Prepaid Single-phase Smart Meter (DIN Rail Mount)

CA168-SF43 is our new generation of Din-rail single-phase electricity meter, with accuracy of Class 1,and its shell is made of polycarbonate flame retardant material.This meter is equipped with a current isolation wire and also supports dual circuit measurement and relays to bring outstanding tamper detection features. The communication with the external keypad(ClU) can be done with either PLC, RF, or by Cable connection. Its installation requirements are also optional.
