main features

By using high-precision sampling measurement units and high-speed MCU data processing units, high-precision and wide range accurate measurement can be achieved.

Adopting modulation and demodulation analog isolation technology based on capacitance effect, the DC voltage and current signals are isolated to 4kV, effectively ensuringEnsure the safety of equipment and personnel.

The working power supply can meet the requirements of 176VAC to 264VAC. Suitable power supply modes for various occasions.

Non volatile memory is used to store various types of data, which can be saved for a long time without loss in case of power failure.

Using a clock chip with temperature compensation function to effectively ensure the accuracy of the clock within the working temperature range.

High accuracy, named after the model of the electric energy meter, and strictly produced according to the requirements of the electric energy meter and applied for a measuring instrument license.

major function

Measurement function: The product separates the connected live wires into separate outputs, which can measure the voltage, current, and power of the output circuitAnd power factor, the maximum load current can reach 60A.

Malignant load, intelligent recognition: using dedicated metering chips and management chips, embedded with patented core algorithms, cleverly identifying inside the dormitoryElectrical characteristics, automatic identification and implementation of on-off for malignant loads.

No need for manual or remote control: Use password protected special commands to control the opening and closing, alarm, and power protection of the circuit.

Power limitation and fire prevention: flexible setting of over power threshold, tripping based on whether the user's electricity consumption exceeds the threshold requirementsJudgment and automatic restoration of power supply.

Time sharing management and disciplinary control: Power on and off management is carried out according to the set time period, with flexible multiple time controls to meet management needsThe needs of the management department.

Prepaid electricity bill and remote recharge: After binding the system with the campus card, electricity can be purchased through the campus card and completed through the systemRemote recharge, in meter billing, and recharge commands have strict security encryption mechanisms.
