Single-phase electric energy meter DDS155

DIN railRS-485digital

Single Phase Smart Din Rail Energy Meter with RS485 Features DDS155 single phase smart din rail meter is a full digital intelligent metering with the special energy measuring chip, microprocessor chip, and SMT craft. It will be used to measure the active energy power and power consumption parameter with the rated frequency 50Hz(60Hz). It has the function of energy measurement and circuit protection. It meets the standard: IEC62052-11, IEC62053-21, DL/T645-1997 and Mod-mus protocol. High accuracy, small size, anti-tamper, low power consumption, anti-harmonic, easily install, etc. Features(★:basic，☆: extra) ★high reliability, low power consumption, long lifespan, wide measurement range, high accuracy ★anti-high voltage and anti-ESD ★guarantee the accuracy of the measurement under the high temperature, high humid climate ☆used in AMR system, remote reading data ☆circuit protection Main Function 1 Energy Power Measurement: positive active power, reverse active power. 2 Output: LED indicator for the pulse output 3 RS485 Communication: Can set up the parameters remotely, and remote reading the data of the power consumption for AMR system. The default baud communication rate: 1200 bps 4 Circuit Protection: Can judge the whole load of electricity, power consumption of single electrical equipment, resistiveness, capacitive character, inductive character. If has some any breakdown or inconformity load, the meter will cut off the power supply through the “Relay”(switch off).
