Description
This meter is used for measuring two phase three wire AC active energy. Made by SMT process, the meter satisfies the standards of IEC62053-21 and IEC62052-11.
Features
1. Active energy is measured bi-directionally and reverse electricity will be measured and counted into total electricity.
2. Reverse indicator will light if the reverse electricity is measured.
3. Impulse indicator light will flicker to show working status when passive pulse outputs.
4. Phase loss LED alert light indicator
5. Measurement for phase loss. The metering precision will not be affected at all if any one phase of the two phase three wire meter cut off.
6. Even after power failure, all data can be stored and lasting for more than 15 years.
7. The width of meter is only 125mm. 35mm DIN-rail installation. Similar shape as 7P breaker.
