D52-2048 Multifunctional DIN-Rail Digital AC Voltage Power Factor Energy Meter

1. Measurement accuracy: 1% plus or minus 2 words
2. Display: Voltage and current display 4-digit red 0.31 inch LED digital tube, active power, apparent power and power factor 5-digit red 0.31 inch LED digital tube
3. Measuring range: AC voltage: AC80-300V 200-450V (select the measuring range according to the equipment)
4. Alternating current: AC0-100.0A, the current display resolution is 0.01A when the measured current is less than 100A, and the current resolution is 0.1A when the current is greater than 100A. Range is automatically converted (decimal point shifts automatically)
5. Active power: (measurement voltage AC80-300V) 5-30000W (AC200-450V: 45000W) starting measurement power 3W normal display
6. Apparent power: (Measurement voltage AC80-300V) 5-30000W (AC200-450V: 45000W) Start measurement
7. Measuring speed: about 2 times per second
8. Dimensions: 54 (length) x80 (width/height) x64 (thickness mm
9. Installation width: =3P (DZ47/C45, air switch position)
10. Dimensions of the protruding part of the meter: 54 (length) x45x (width/height) x16 (thickness/depth) mm
11. Installation method: track type
12. Built-in transformer: the wire of the measuring circuit passes through the round hole on the right side of the instrument (the hole diameter 11MM can pass through the maximum 12 square (mm) standard copper wire / can meet the load maximum current 100A) Note: The load passes through the round hole of the instrument Pass through from above or below without affecting current measurement accuracy
13. The external transformer (hole diameter 15.5mm) can meet the national standard 21-25 square (mm) standard copper wire passing through

Use and wiring method
1. Connect the measured voltage to the terminals 1 and 2 on the bottom left of the meter
2. Connect the external transformer according to the wiring diagram in Figure 1. Connect the two wires of the secondary end of the precision current transformer with the instrument to the 3 and 4 terminals on the upper left, and pass the wires of the measurement loop through the transformer. Round hole
3. The built-in transformer is wired according to the wiring diagram in Figure 2, and the wire of the measurement circuit passes through the round hole on the right side of the meter. The threading direction of the wire can be selected by the user according to the use situation. It can be inserted from the bottom round hole on the meter. Or pass through the circular hole on the top of the meter and come out from the bottom. The different penetration directions will not affect the measurement results
