DIN RAIL METER

Type DDS6789/DTS6789 Department of energy
Meter guide my latest research and development of new rail energy meter.
Technical performance of the meter in full compliance with international
standards IEC62053-21 in a single, three-phase active energy meter relevant
technical requirements, able to direct precise measurement of the rated
frequency of 50 HZ or 60HZ, single, three phase AC power system load, active
power consumption. The meter by 7 LCD display or displays of degrees has the
function of electricity, and built and has far-infrared RS485 communication
module to faciliate connection with a wide range of AMR system. Products have
advantages of good reliability, small size, light weight, good looks, easy to
install.

Structural
characteristics and working principle

1.35mm DIN standard rail installation, in
line with DIN EN 50022 standard, or board before the installation(mounting hole
center distance of 63mm), two types of installation by the user selection.

2.10 width (find the number of 12.5mm), in
line with the standards JB/T7121-1993

3. Optional 6+1 bit(999999.1kwh, default)
or 5+2 digital display, by the user through the far-infrared or RS485 data
communication poert arbitrary set.

4. Equipment has a level close-up of
passive energy pulse output ports and a class of passive remote power pulse
output port (pulse output rate of 10 or 100imp/kwh option), in line with the
IEC62053-31 and DIN43864 standard

5. Equipped with an infrared data
communication port and RS485 data communication port, the standard
configuration DL/T645-1997 standard communications protocol in line with the
use of the other communication protocol.

6. 6 LED instructions separately for each
phase power status and close-up energy pulse signals and remote power and data communication
pulse signals status

7. Automatically detects the load current
direction, by a separate LED instructions.
