ECO021AG

 3 Available as 35mm DIN standard rail mounted, conforming to Standards DIN EN 50022, as well as front PANEL mounted (the center distance between two mounting holes is 63mm). Two mounted methods above are optional for user.
 10 pole width (modulus 12.5mm), complying with Standards JB/T7121-1993.
 Can select the step motor impulse register of 6 digits (999999kWh) or 6+1 digits (999999.1kWh) LCD display.
 Can select the inside far infrared data communication port and RS485 data communication port. The communication protocol complies with Standards DL/T645-1997. The other communication protocol can also be option.
 Can select the maintenance free lithium battery inside for LCD display to read the meter while the power is cut.
 S-connection (inlet wire from bottom and outlet wire on top) has two connection types: direct connection and CT connection for option. For CT connection, there are 27 kinds CT rates to set, after setting CT, we can read the meter directly, no need multiplying the CT rates.
 The CT connection meter is 7 digits LCD display: 5+2 digits (only at CT rate is 5:5A) or 7 integers, which is depended on the setting CT rate.
 Equipped with a polarity passive energy impulse output terminal, conforming to Standards IEC 62053-31 and DIN 43864.
 LEDs indicate separately the power state on each phase, the energy impulse signal and data communication state.
 Automatic detection for the load current flow direction and will be indicated by LED.
 Measure the active energy consumption in one direction on three phase, which is not related with the load current flow direction at all, complying with Standards IEC 62053-21.
 The short terminal cover is made with the transparent PC, to reduce the installation space and is convenient for centralized installation.
