Brief Introduction:
Eastron SDM320 series is single phase two wire Din rail meter. SDM320M is multifunction meter
for measuring kWh, kW, V, A, Hz, PF, MD etc with RS485 Modbus protocol. The data can be
transported by isolated RS485. It is provided with a nonvolatile memory system that the readingare not lost or altered when power off. It uses advanced special recording integrated circuit with high
precision. It is highly accurate, durable, reliable, low power consumptive, without reversion, creep-proof,
antI tampering, and bilateral recording with strong overloading capability. It conforms to the related requirements
of IEC62053-21 , and pass EN61326-1:2006 and EN61010-1:2010 in world famous Lab.
