Din Rail Energy Meter (Din Rail Watt Hour Meter, Din Rail KWH Meter)

D3702

Display mode:
LCD

Display format:
①XXXXXX.XX(6-digit integer + 2-digit decimal)


Description
This electric meter is designed to measure three phase four wire AC active energy, suitable for three phase electric equipment and small and medium-sized enterprises and institutions, commercial and residential users who are charged by flat rate tariff. The meter meets IEC62053-21 and IEC62052-11 standards. Meter reading can be achieved by RS485 communication network.

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. RS485 data communication terminal, compatible with DL/T645-2007 and MODBUS-RTU agreements.
7. Far infrared communication available.
8. While power cut, all storage data will not lose and can be saved for more than 15 years.
9. Meter width is only 125mm. 35mm DIN-rail installation. Similar shape as 7P breaker.

Optional Function
Electric quantity will display and battery power while black out. (can be customized)
