CDM35-U Series din rail meter
1. Application:
CDM35-U Series din rail installation energy meter is researched and developed by CHIQI electric. It adopt microelectronics technology and import large-scale integrated circuits and the application of advanced digital sampling processing technology and SMT process, we have our own copyright, it is the new model and lowest mass single phase two wire meter.The quality and performance is complied with GB/T17215.321-2008.It has feature of high stable, small mass, light weight, ingenious design.
2. Function and feature
35mm standard din rail installation, it is according to DIN EN50022 standard
Two pole width( modular 35mm), according to DIN43880 standard
Standard counter display (5+1 digital) and LCD display
Double LCD display, the up LCD can test the electricity power, the under LCD can display the total electricity power, can not back to zero.
Standard pulse output(with anode),free connection with all kinds of AMR, according to IEC62053-21 and DIN43846+
Double LED indicator display power state (green light) and pulse signal (red light)
RS485 communication entrance, the communication agreement is DL/T645-1997 or MODBUS-RTU.
It can measure energy power electricity, voltage, current, power rated, power factor, frequency, etc.
Measure one way single phase two wire energy, it is none of business with load current way. The performance is according to GB/T17215.321-2008
Direction connection, standard S type connection wire.
Connection box cover for safety purpose
