Henan Star Hi-Tech Co., Ltd. [China]

Detailed Product Description

Brief introduction:

This type of meter is designed as an intelligent hi-tech electronic energy metering product, with characteristics of signal digit arithmetic, digital filtering, digital error correction, digital adjustment, insensitivity to the temperature influence, and good stability.

Standards:

IEC687:1992, IEC1036:2000 and other correlative international standard;

DL/T641-2007, DL/T645-1997 and other correlative Chinese standards

Technical parameters:

1) Specification table:

2) Rated frequency: 50Hz

3) Working voltage:  0.8-1.2 rated voltage

4) Clock error: ≤±0.5s/d (reference condition)

5) Power consumption: ≤2W 4VA

6) Pulse width: 80(±10)ms

7) Clock battery life: clock standby battery: ≥30 years, continuously power-off duration: >6 years

Main function:

1)      Metering function: can register forward and reverse active and reactive energy under 4 tariffs

2)      Demand function: can register the maximum demand of total energy and forward and reverse active and reactive energy under 4-tarrifs

3)      Auto-billing function: 2 billing ways (monthly billing, weekly billing), and each billing way can at most set 8 times of auto billing

4)      Display function: adopt big screen LCD display, can display each kind of metering data, current power state, meter state and setting parameters and others, two ways of display can be chosen by users

5)      Parameters set: can select PC or palmtop to program, these two programs will prevent un-authorization operation in order to protect data safety

6)      Reset function: 4 reset ways of manual, RS485, infrared, automatic to be chosen

7)      Event log function: can record the data and time of loss of phase, voltage and current; current unbalance; can record the time of overload and under-voltage ratio

8)      TOD billing: pre-define 4 tariffs, 4 segmentation in a year, 20  time section in a day, and each time section for 1 minute at shortest and 1 day at longest  

9)      Meter reading function: can set 4 types of meter reading: manual meter reading, palmtop meter reading, power-down meter reading, RS485 meter reading.

Pulse output interface: with optional; isolation active, reactive, three-way remote pulse, second signal output interface, and there is energy pulse indication on the meter board
