INTRODUCTION :
JSY-MK-333 three-phase embedded metering module is a measurement product
developed by our company using microelectronics technology and special large-scale
integrated circuits, applying digital sampling processing technology and SMT process and
other advanced technologies, and has completely independent intellectual property rights.
The technical performance of the measurement module meets the relevant technical
requirements of the IEC 62053-2 standard in the 1.0 three-phase active energy meter, and
can directly and accurately measure the voltage, current, power, power factor, reactive
energy and other electrical parameters in the three-phase AC grid with a rated
frequency of 50Hz or 60Hz. The module has built-in 1 RS485 communication interface, 1
TTL interface, sampling MODBUS-RTU communication protocol, which is convenient for
connection with various AMR systems, and has the characteristics of good reliability, small
size, light weight, beautiful appearance and easy installation.
JSY-MK-333 three-phase embedded metering module can be widely used in
energy-saving transformation, electric power, communications, railways, transportation
, environmental protection, petrochemical, steel and other industries, used to monitor
the current and power consumption of AC equipment.
1.2、 Functional features
1.2.1. Collect three-phase alternating current parameters, including voltage, current,
power, energy and other electrical parameters, complete information.
1.2.2. Adopt special measurement chip, effective value measurement method, high
measurement accuracy.
1.2.3. With 1 RS-485 communication interface, 1 TTL communication port (3.3V).
1.2.4. The communication protocol adopts standard Modbus-RTU, which has good
compatibility and is easy to program.
1.2.5. RS-485 communication interface with ESD protection circuit.
1.2.6. Two power supply methods are optional, which can be powered by fixed DC3.3V
or DC 5~12V.
1.2.7. It adopts industrial-grade chip, built-in watchdog, and has perfect lightning
protection and anti-interference measures to ensure reliability.
1.2.8. High isolation voltage, withstand voltage up to AC: 2500V.
1.2.9. Optional single-turn through-center transformer or open-close transformer
with different specifications, which is convenient and easy to use.
(Note: The opening and closing current transformer is mainly used in industrial urban
networks, power transmission systems, and rural project transformation
Easy installation, no need to disassemble the bus bar once, can also be operated with
electricity, and does not affect the normal power consumption of customers, for the user
transformation
The project saves a lot of manpower, material and financial resources and improves the
efficiency of transformation. )
1.2.10. The module size is 65*57*41mm (length * width * height), small size, easy to
embed into other systems
.
