Description
The two types of electricity meters are used to measure single phase two wire AC active energy. Utilizing SMT (Surface mounting technology) to manufacture, the meters completely accord with the international standard IEC62053-21.

Features
1. Active energy is measured bi-directionally and reverse electricity will be measured and counted into total electricity.
2. Reverse indicator light
3. Power indicator lights
4. Impulse indicator light will flicker to show working status when passive pulse outputs.
5. Two kinds of case shells available: Protection I or Protection II.

Optional Function
1. Dead battery display added (E1311L only)
2. 48-hour supercapacitor power cut display added (E1311L only)
3. Shell sealing utilizes ultrasonic welding instead of screw sealing.
