Application:
Model XTM1250SA three phase four wire electronic DIN rail active
energy meter is a kind of new style three phase four wire active
energy meter, it adopt micro-electronics technique, and imported
large scale integrate circuit, use advanced technique of digital
and SMT techniques, etc.
The meter completely accord with relevant technical requirements of
class 1 three phase active energy meter stipulated in international
standard IEC 62053-21. It can accurate and directly measure 50Hz or
60Hz active energy consumption from three phase four wire AC
electricity net.
This meter has seven digits LCD displays shows the active energy
consumption. Contact with all kind of AMR system conveniently It
has following features: good reliability, small volume, light
weight, specious nice appearance, convenient installation, etc.
This meter has already got the patent certificate from China State
Intellectual Property Office at present. Patent certificate NO.
2012 3 0473416.7, any other country patent certificate are in
assessing.
Functions and features:
● 35mm standard DIN rail installation , complying with standard DIN
EN50022. Or front board installed (mounting holes center distance
63 mm), users can choose any one by themselves.
● Ten pole width (Modulus 12.5mm), complying with standard
JB/T7121-1993.
● Type S wiring (Inlet from bottom, outlet from top).
● Seven digits display LCD, 6+1 digits display (999999.1 kWh)
● There are a polarity port of pulse output passive closed and a
nonpolarity port of pulse output passive distant (the output rate
is 10 kWh/pulse), ). Complying with standard IEC 62053-31 and DIN
43864.
● Six LED instructions respectively every power supply state,
signal of closed energy impulse and distant energy impulse and data
communication state.
● Automatic detection the direction of the flow of load current.
And Instructions on individual LCD
● Single direction three components measure three phase four wire
active energy consumption. It is nothing with direction of the flow
of load current. Complying with standard IEC 62053-21.
● Standard configuration short terminals cover, may select
extension terminals cover, in order to protect to use safety.
