China Manufacturer DTSY5558 Three Phase Prepared Smart Energy
Meters
1. General
DTSY5558 three phase electronic prepayment watt-hour meter adopts
micro-electronic technology, it has high precision and low power
consumption, the performance can complies with IEC 61036.
It adopts large-scale integration (LSI) and surface mounting
technology (SMT), the main components use international famous
brand, so the meter has high reliability and long service life. The
meter case uses fire-resistant ABS material, and the structure of
the meter is air-proofed. Single-chip processing system in the
module responsible for the data operation.
The purpose of developing this meter is controlling electricity
consumption. Users should purchase the electricity enable the meter
running. The meter can remind the user to purchase the electricity
by alarm when the electricity remained is limited, and switch off
the power supply automatically when the electricity use up. It’s
also able to limit maximal consuming power. Each meter match with
one memory card, and the meter can exchange the data with card
bi-directionally through the card read device. User won’t lose
electricity even he lost the user card, because a renewed card is
acceptable.

4. Functions
4.1 Total consumption and remain energy display by LCD
4.2 Accumulate the electricity purchased
4.3 Limit maximal power
4.4 Automatic switch off power when overload
4.5 Warning when electricity insufficiency
4.6 Cut off the power when electricity use up
4.7 Pulse output
4.8 Operation indicated by pulse LED
5. Working principles
The meter collects voltage signals from the potentiometer. The
current signals collected from the shunt to get multiplying signals
through multiplication device, and after frequency converting, get
counting pulses, which is in direct ratio with the product of
voltage and current.
The counting pulses of electric energy will be sent to CPU for
processing through electro-coupling, and be stored in nonvolatile
EEPROM after operation. These pulses and information from IC card
that been stored with some volume of electricity and data of
supervisory demands will be processed by micro processing system in
the meter then provide signals of display, warning and cutting-off
state etc.
Diagram is as follows:
6. Installation
The meter must be connected according to connection diagram curve
in the meter. It is required to tighten the screws and well connect
the conducting plate in the terminal block. For CT operated meter,
the actual volume of electric energy shall be the reading indicated
by the meter multiplying the CT ratio.
7.Relevant accessories and apparatus
8.System
Plz pay attention:One meter equiped one card for free,vending system will be provided
with a CD,Card reader is charged separately,If you buy 500 units
,the card reader will be free.
