| Application |
|
Model DEM061AL three phase four wire electronic front board installed multifunctional active energy meter is a kind of new style three phase four wire active energy meter. The meter completely accord with relevant technical requirements of class 1 three phase active energy meter stipulated in international standard IEC 62053-23 and class 2 three phase reactive energy meter. It can accurate and directly measure 50Hz or 60Hz active energy consumption from three phase four wire AC electricity net. This meter has LCD displays shows the active energy consumption, and there are far infrared and RS485 communication module in it, contact with all kind of AMR system conveniently. It has following features: good reliability, small volume, light weight, specious nice appearance, convenient installation, etc.

| Functions and features |
Front board three fixed installation, the cover is made of PC material which is transparent and anti-UV molded overall, the bottom of the meter and the terminal is made of quality bakelite material which is moisture-resistant, fire-retardant, high temperature molded overall. It has following features: good weather ability, high rigid, good insulation performance, etc.
Have six tariffs, may select 12 daily period of times. You can set the date arbitrary which can automatic read the meter every month. May select single tariff function in weekend. (Please specified when ordering).
There are a clock and Maintenance-free backup lithium batteries in it. Battery capacity detection and display all the time. It can keep the electricity data for 12 months. The data can be kept forever after power cut off.
May select cycle display (default) or push the button itemized display, it can display 14 data at most. Can select the data which displayed. The decimal median which displayed can choose set one or two.
There are a polarity port of pulse output passive closed and a nonpolarity port of pulse output passive distant (the output rate is 10 or 100 imp/kWh, can select ). Complying with standard IEC 62053-31 and DIN 43864.
There are far infrared and a port of RS485 communication data. It is use for setting and reading the meter. Set and operation have password protection, communication agreement complying with standard DL/T645-1997.
Ten LED instructions respectively power supply state, signal of energy impulse, the direction of the flow of load current, the state rates just now and the data communications state.
Detect active and reactive energy, active and reactive power, voltage, current and frequency, etc. of three phase four wire forward and reverse. Complying with standard IEC 62053-21 and IEC 62053-23.
Standard configuration direct connect operation, type 16B wiring, we can also choose another type of wiring, and use CT (Product Configuration code is AO) and PT & CT (Product Configuration code is AQ) for operation.
Standard configuration short terminals cover, may select extension terminals cover, in order to protect to use safety. (Product Configuration code is AL). |
