Item Type: Electricity Meter <br>Material: ABS <br>Model: D52-2066 <br>Usage: Used in chemical industry, power plants, automation equipment, DOS systems, electromechanical equipment, etc. <br>Basic Parameter: <br>Main Specifications: <br>1. Measurement Accuracy: 1% ± 2 words <br>2. Measuring Range: <br>AC Voltage: AC 250-450V <br>AC Current: AC 0-100.0A, the current display resolution is 0.01A <br>Power Frequency: 45.0Hz-65.0Hz <br>Power Factor: 0.00-1.00PF <br>Active Power: 0-45000W, the display resolution between 0-9999.9W is 0.1W, the rest is 1W <br>Electric Energy: 0-99999kwh, the minimum display resolution between 0-999.99kwh is 0.01kwh, between 1000.0-9999.9kwh is 0.1kwh, between 10000-99999kwh is 1kwh <br>3. Measurement Speed: About 2 times per second <br>4. Installation Method: Rail type <br> <br> <br>How to Use: <br>1. Connect the measured voltage to the 1 and 2 terminals on the lower left of the meter. <br>2. Built in transformer wiring according to the wiring diagram in Figure 1: Pass the wire of the measurement loop through the round hole at the bottom of the instrument, user can choose the direction of the wire according to the situation, it can pass through the round hole at the bottom and come out from the top, or pass through on the top and come out from the bottom, different directions will not affect the measurement results. <br>3. External transformer wiring according to the wiring diagram in Figure 2: Connect the 2 wires of the secondary end of the transformer to the terminals 3 and 4 on the upper left of the instrument respectively, and pass the wires of the measurement loop through the round hole of the transformer. <br>4. After the power is turned on, the instrument displays the measurement parameters. <br>5. When it is necessary to reset the electric energy measurement, press and hold the RESET button on the right side of the instrument panel for 5 seconds, until the electric energy is displayed as 0, release the button, and the electric energy will be measured from 0. <br>6. The electric energy has the function of automatically saving the data when the power is cut off, when the measuring voltage is disconnected or the power is cut off, the meter will automatically save the current test data, and when the measuring power is reconnected, the meter will continue to accumulate the previously saved data. <br>7. The diameter of the built in transformer (CT) round hole is approx.11mm/0.4in, which can pass through the national standard 12mm2 standard copper wire, can meet the load current 100A through <br>8. The diameter of the external transformer (CT) hole is approx.15mm/0.6in, which can meet the national standard of 21-25mm2 standard copper wire.<br>1、Color LCD Screen: The electricity meter adopts full view color LCD screen with a wide viewing angle of 178°, clearly observe electricity usage <br>2、Parameter Display: The energy meter can simultaneously display AC voltage, AC current, active power, power factor, frequency and electric energy <br>3、Convenient Observation: The electricity consumption of electrical appliances in the whole house is clear at a glance, convenient to observe <br>4、High Strength ABS Material: This power meter is made of ABS material, features high strength, good toughness and long last durability <br>5、Widely Application: This electricity meter is widely used in chemical industry, power plants, automation equipment, DOS systems, electromechanical equipment, etc.The measuring voltage range of this instrument is 250?450V, which is only suitable for the pure AC 45?65Hz mains power supply.1 x <br> <br>Electricity&nbsp;Meter<p>1 x Manual</p>
