Din Rail Three Phase Modbus Digital Kwh Meter Smart Electric Meters
With RS485
Product circuit measurement part of a dedicated measurement chip,
high reliability, high precision and accurate measurement of active
energy. The product adopts the linear power supply, the metering
chip converts the electric energy into pulse respectively. The
microprocessor completes the functions of power collection, power
calculation, power pulse output and LCD display processing. The
data security adopts redundant design, and the data adopts multiple
backup to ensure reliable measurement data.
We can supply a wide range of products suitable for 100VAC to
380VAC (50 or 60Hz). In addition to our regular power meters, we
have developed our own prepaid smart card form, prepaid smart track
card form, rechargeable smart card. As well as a complete set of
PC-based pre-paid management operating system. For more
information, please contact us.
