ENERGY METER WATT METER CURRENT MONITOR LCD DIN 100A 300V RMS Information about this product 6 in 1: This multifunctional LCD digital electricity meter can measure the values of these useful and necessary measurements and provide values - voltage, current, electrical power, energy, frequency and power factors. Color LCD Display: Wide viewing angle 178 degree, clear and easy to read Energy Consumption Monitor: this DIN rail electricity meter can help reduce energy consumption and save money Automatic memory and memory function: When turned off, electricity data is saved and stored, KWh counter can be reset Features: It is characterized by low power consumption, high precision, high overload current and anti-theft Specifications: Measurement accuracy: 1% ± 2 characters Measuring range: AC Voltage: AC 40-300V AC Current: AC 0-100A Current display resolution is 0,01A Power Frequency: 45,0 Hz - 65,0 Hz Power factor: 0,00-1,00PF Measurement speed: about 2 times per second Overall Dimension: 54 x 80 x 64 Installation Method: Guide Rail Type Active power: Measuring range: 0 - 45000W Display Resolution: 0,1W (0 - 9999,9W); 1W (10000 - 45000W) Electricity: Measurement range: 0-99999kwh Display resolution: 0,01kwh (0-999,99kwh); 0,1kwh (1000,0-9999,9kwh); 1kwh (10000-99999kwh) Application and method of wiring: 1. Connect the measured voltage to terminals 1 and 2 in the lower left corner of the meter. 2. Built-in transformer according to Figure 1 of the wiring diagram, wire measuring circuit through the lower hole of the instrument, wire towards the user according to any choice, either from the instrument below the hole to the upper exit, or from the instrument above the round hole through the upper output, or from the instrument above the round hole to the upper output. 3. The external wiring of the transformer according to the wiring diagram in Figure 2 will be connected to the instrument by means of a precision current transformer at the secondary end of the two wires connected to the instrument in the upper left corner of terminals 3 and 4. Connect the two secondary terminal wires of the precision current transformer with the instrument to the terminals 3 and 4 in the upper left corner of the instrument and run the measuring circuit wires through the transformer hole. 4. The meter will display the measurement parameters when the power is turned on. 5. To reset the power measurement (when measuring from scratch), press and hold the button on the right side of the meter panel (RESET) for 5 seconds (press and hold for 5 seconds) until 0 appears on the display, then release the button. When 0 appears on the display, release the button and the power will be measured from scratch. Electricity ma automatic data recording function in case of power failure, i.e. When the measuring voltage is disconnected or a power failure occurs, the meter will automatically record the data. This means that when the measuring voltage is disconnected or a power failure occurs, the meter will automatically save the current test data, and when reconnected to the measuring power supply, the meter will continue to sum up the originally saved data.
