Functions and features:
● 35mm standard DIN rail installation, complying with standard DIN
EN50022.
● Ten pole width (Modulus 12.5mm), complying with standard
JB/T7121-1993.
● Standard configuration 5+1 digits display (99999.9kWh) by step
motor impulse register.
● 5 LED instructions respectively power supply state (phase voltage
A,B,C) and REV.signal of closed energy impulse.
● Automatic detection the direction of the flow of load current.
And instructions (signal of closed energy impulse is green when
working, that is meaning the direction of the flow of load current
reverse).
● Single direction 3 components measure 3 phase 4 wire active
energy consumption. It is nothing with direction of the flow of
load current. Complying with standard IEC 62053-21.
● Standard configuration type S wiring (Type U)) for direct connect
operation, we can also choose another type of wiring, and use 5+1
digits display by impulse register, (Type U CT ).
● Standard configuration short terminals cover, may select
extension terminals cover, in order to protect to use safety.
Application:
Model XTM1250S-U 3 phase 4 wire electronic DIN rail active energy
meter is a kind of new style two phase three 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 3 phase 4 wire AC electricity
net. It can display total energy consumption by step motor impulse
register. 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. ZL
2013 3 0556168.7, any other country patent certificate are in
assessing.
