Product Overview

Working Conditions

Environmental air temperature: General area upper limit+40 °C, lower limit -10°C; altitude: 1000 meters.
Relative humidity:daily average not exceeding 95%, monthly average not exceeding 90%.
Water vapor pressure: daily average not exceeding 2.2Kpa, monthly average not exceeding 1.8Kpa.
When the temperature drops, condensation may occur accompanied by dirt, and this product is suitable for two more harsh environmental conditions than normal.
Condensation is infrequent (no more than twice a month on average) with slight dirt.Generally,there is no condensation (no more than twice a year on average) and there is more serious pollution
There is no danger of fire, explosion, or severe dirt in harsh environments such as gases that can corrode metals and damage insulation.
There are no places with severe vibrations, bumps, or vertical inclinations not exceeding 8°.
