YUMO NP-VAM Din Rail Display meter
Technical Parameter
Supply Voltage / Frequency Range | AC 50V-500V / 50-60Hz |
Discrepancy Range | ± 2% |
Operating Voltage Range | AC 50-500V |
Rated Insulation Voltage | 660V |
Current Display Range | AC 1-63A |
Degree of Protection | IP20 |
Environmental Protection Rating | 3 |
Sample rate | About 1 time/s |
Application Method
1. Connect the measure voltage to the 1 and 2 terminal
2. Connections of meter with internal current transformer as graph 1. Make the wire through the hole in the meter and the direction chose arbitrarily.
3. Connections of meter with external current transformer as graph 2. Make the wire through the hole in the meter, and connect the two wires of the secondary transformer to the 3 and 4 terminal.
4. When power on, the meter display the measure parameters.
5. When power on, you can press the button of SAM CK last for 5 seconds, then the electric energy will to be zero and start to cumulate when release the button. And when power off, the meter can save the value of electric energy and go on cumulating data when the meter power-on next.
