DEM481RC

THREE PHASE FOUR WIRE ELECTRONIC MULTI-RATE PREPAYMENT FRONT BOARD INSTALLED ACTIVE ENERGY METER

Application

Model DEM481RC three phase four wire electronic prepayment front board installed active energy meter is a kind of three phase four wire active energy meter which purchase electricity by IC card, electric energy measuring, load control and using electricity management. The meter completely accord with relevant technical requirements of class 1 single 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, it is use for setting indoor or out door meter box. This meter has LED displays shows power. And there is far infrared communication module in it, can read the meter and set the system parameters conveniently. It has following features: good reliability, light weight, specious nice appearance, convenient installation, etc.

Functions and features

Standard configuration one meter one card, can repeat input money from PC machinery which with IC programmer.
There a clock which is implement ladder rate, and there is far infrared communication module in it, use for checking the clock, reading the meter and setting the system parameters.
It has IC card with code and data against false, standard configuration use storage IC card, may select logic encryption card (Product Configuration code is RG) or non-contact RF card. (Product Configuration code is RK)
Standard configuration payment by kWh, may select payment by money. (Please specified when ordering).
Standard configuration of the prepayment management system use of single edition, may select network edition. (Please specified when ordering).
It has load control and function of automatic fault detection and instructions, standard configuration without function of open terminals cover and detection, may select open terminals cover and cut power. (Please specified when ordering).
6 LED digits display, 5+1 digits display (99999.1kWh), may select 7 LCD digits display. (Product Configuration code is SC).
A port of pulse output passive closed (polarity), complying with standard IEC 62053-31 and standard DIN 43864.
Five LED instructions power supply state, signal of energy impulse and direction of the flow of load current.
Automatic detection the direction of the flow of load current. When the yellow LED display, that is meaning the direction of the flow of load current reverse.
Single direction three component 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.
Direct connect operation, type 16B wiring, may select three phase three wire, direct connect operation, type 13B wiring (Product Configuration code is RD).
Front board three fixed installation, standard configuration short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is RA).
