They are installed in mines, underground mine working, on gas-distribution stations and etc. They provide for proper operation under explosive atmosphere.
Operation conditions.
Climatic environmental factors:
- ambient temperature upper value is 308 K (35C);
- ambient temperature lower value is 263 K (minus 10C);
- relative humidity upper value is 98% at temperature of 308 K (35C);
- the rectifier should provide for reliable and stable operation after being in inoperative state at temperature ranging from 233 to 333 K (from minus 40 to plus 50C).
The rectifier mass (gross) in shipping container, max. 3300 kg.
Overall dimensions (width x depth x height) - 1476 x 1472 x 2304 mm.
