1. GENERAL
ADL Series DIN mounting kWh meter is a kind of smart energy meter. They include ADL-100 (the single phase kWh meter) and ADL-300 (the 3-phase kWh meter). It adopts micro-electronics technique, and it has many advantages such as compact, light, delicate, accurate, with the counting of multi tariffs energy. With their good capability of anti-emi and low-power, they comply with international standard IEC 60136 and IEC 60512.
