Description
These two types of electricity meters are used to measure three phase four wire AC active energy. They are made by SMT (Surface mounting technology) process and conform to 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 electricity will be measured. Reverse indicator light available.
3. Passive pulse output, impulse indicator light will flicker while the meter is working.
4. Phase loss LED light indicator
5. Measurement for phase loss. The metering precision will not be influenced if any one phase or two phases of three phase four wire meter cut off.
6. Two kinds of case shells available: Protection I or Protection II.
Optional Function
1. LCD shows two kinds of electricity bi-directionally. Forward and reverse electricity could be showed independently. (E3401L only)
2. Dead battery alert display (E3401L only) added
3. 48-hour supercapacitor power cut display (E1203L only) added
4. Shell utilizes ultrasonic sealing instead of screw sealing
5. Built-in three phase current and voltage connection hook, equipotential anti-tamper design.
