DDS5558 Single Phase Meter

DDS5558 Single Phase Meter is a kind of new style single phase two wire active energy meter, it adopts micro-electronics technique, and imported large scale integrate circuit, use advanced technique of digital and SMT techniques, etc. It has minimum size, and also a new single phase two wire active energy meter. It has already passed the test of the international authority CE.

The meter completely accords with relevant technical requirements of class 1 single phase active energy meter stipulated in international standard IEC 62053-21. It can accurately and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net. This meter has white backlight source eight digits LCD monitors shows the active energy power consumption. It has following features: Good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.
