Product brief introduction
Application Type DDS298-1 single phase DIN rail watt-hour meter is a kind of new style single phase electronic watt-hour meter, it adopts micro-electronics technique, and imported large scale integrate circuit, using advanced technique of digital and SMT techniques etc. The meter completely accords with relevant technical requirements of class land class2 single phase energy meter stipulated in National standard GB/TI7215-2002 and international standard IEC62053-21 (IEC61036). It can accurately and directly measure 50Hz or 60Hz active energy consumption from single phase AC electricity net, it can display total energy consumption by step type impulse register. It has following features: Good reliability, small volume, light weight, specious nice appearance., Convenient installation, etc.
Functions and features
