Line power failure will not affect the accuracy of measurement of three-phase three-wire DIN rail meters
Meters the largest of three-phase three-wire Guide feature is a three-phase power supply, whether it's energy meter in any line or two-line there is a power failure, will not affect the accuracy and precision of measurement. A lot of users in the use of the process in there is a power failure and unable to record and log the error in case of power cut, in order to solve this problem for three-phase three-wire guide-meter special human is equipped with a battery, if there is no power and can have a standby power supply in case of electricity providing rear. In order to meet the different needs of different users, led to a lot of different products like zero-phase rail-meter, three-phase multifunctional rail electricity and rail-type three-phase four-line multifunction meter, from nature, they are the same, but there is a great deal of improvement and development.
