Product description
1. Accuracy and Measurement Range
- Accuracy: 1% ± 2 digits
- AC Voltage: AC 40.0-300.0V. The measurement range is 40-300V, with no restrictions, suitable for grid power, photovoltaic, and inverter currents. The range of 250-450V is only applicable to 380V AC.
- Current: AC 0-100.0A, with a current resolution of 0.01A.
- Frequency: 45.0Hz – 65.0Hz.
- Power Factor: 0.00-1.00PF.
- Electric Power: 0-450,000W. When measuring electric power in the range of 0-9,999.9W, the resolution is 0.1W; otherwise, the resolution is 1W.
- Electrical Energy: 0-99,999kWh. When measuring electrical energy in the range of 0-999.99kWh, the resolution is displayed as 0.01kWh; when measuring in the range of 1,000.0-9,999.9kWh, the resolution is displayed as 0.1kWh; when measuring electrical energy greater than 9,999.9kWh, the resolution is displayed as 1kWh.
- Two measurements per second.
- Installation Method: DIN rail mounting
- Connect the measured voltage to terminals 1 and 2.
- For meters with built-in current transformers (see Figure 1): Pass the wire through the hole on the meter, with no specific direction required.
- For meters with external current transformers (see Figure 2): Pass the wire through the hole on the meter and connect the two secondary wires of the transformer to terminals 3 and 4.
- After powering on, the meter will display the measured parameters.
- Zeroing Operation: After powering on, press and hold the SAM CK button for 5 seconds, and the electrical energy will be reset to zero. Release the button to start accumulating. When power is cut off, the meter can save the electrical energy value and continue to accumulate data upon the next power-on.
- The meter is only suitable for measuring AC mains with a frequency of 45-65Hz.
