2.3 Environmental conditions
Working Environment:
Operating temperature:-25℃~+55℃. The wettest month's monthly average maximum relative
humidity is 90%,while the monthly average minimum temperature of the month is 25 °C and no
condensation in the surface,While the maximum temperature is +40 °C,the average maximum
humidity does not exceed 50%
Storage Environment:
Storage temperature: -30℃～+75℃; Relative humidity: <80%
Stored rain and snow proof indoors. Ambient air does not contain acidic, alkaline or
erosive and explosive gas; no excitation is applied under the limit value, there is no
irreversible change in the device. After the temperature is restored, the device should
work normally.
Atmospheric pressure:(80kPa-110kPa <relative altitude <2km)
2.4 EMC performance

Can stand with of 1MHz and 100kHz damped oscillation wave pulse group leveling test
according to G B/T14598.13-1998 (the first half-wave voltage amplitude is 2.5kV, the
differential mode is 1kV)
Fast transient immunity: GB/T14598.10-1997, level 3
Radiated electromagnetic field immunity: GB/T14598.9-1995, level 3
Electrostatic discharge: GB/T14598.14-1998-4.1, level 3
2.5 Electrical insulation performance
Insulation resistance: Using open circuit voltage 500V measurement instrument to test
between each charged conductive circuit and ground (outer casing or exposed non-charged
metal parts), between AC and DC circuit, between AC current circuit and AC voltage circuit,
the instrument tests its insulation resistance value should not be less than 100MΩ.
