M381 ammeter, voltmeter M381 (M 381, M-381; m381; m 381; m-381)
M381 ammeter, voltmeter M381 - panel meter-coil system for measuring current and voltage in the DC link.
Accuracy class - 1.5.
Overall dimensions - 120×120× 60mm.
Vibration, impact resistant, splash-proof.
Ammeters M381 and voltmeters M381 have a measuring system with a magneto system vnutriramochnym magnet and moving part in the drill cores.
The values ranges M381 devices with the zero mark, and how their inclusion are shown in Table 1.
Ammeters M381 and voltmeters M381 admit the error of measurement equal to ± 1,5% of the final value of the measuring range - for units with the zero mark on the left and the amount of the final value of the measuring range - for units with a zero mark in the middle of the scale.
Operating conditions M381
Ammeter M381 and voltmeter M381 designed for use at temperatures from -40 º C to +60 º C. Relative humidity should be no more than 95% (at +35 º C).
Devices M381 made in the body splash proof.
Positioning and mounting M381
Ammeters M381 and voltmeters M381 designed for flush mounting on vertical or horizontal panels (panels) made as of the magnetic and non-magnetic materials.
When mounting the M381 must adhere to the following rules:
- Installation of equipment should be made carefully, without distortions;
- Fastening ammeters M381 and voltmeters M381 panel must be rigid and not create additional stress;
- Ammeter M381 and voltmeter M381 mounting should be located away from sources of strong magnetic fields with a strength greater than 0.4 kA / m;
- Appliances intended for inclusion in the network with a voltage of more than 650V, mounted on insulators of reach to touch.
The manufacturer guarantees that the device specification requirements under normal use, storage, transportation and installation. Guaranteed shelf life ammeter and voltmeter M381 M381 - 6 months from date of manufacture. Guarantee period - 4 years from the date of commissioning the device.
Ammeter M381 and voltmeter M381 compliant, ensuring the safety of life, health, consumer and environmental protection.
