Product introduction

Working Conditions:
1. Ambient temperature: -5°C ~ +40°C; 24h average temperature:≤ +35°C
2. Atmospheric condition: clean air; relative humidity ≤50% when it is +40°C; higher humidity is allowed upon lower temperature (i.e., 90% humidity at +20°C); be careful that condensation might be occurred because of temperature change
3. Altitude: ≤2000m
4. Transportation and storage temperature: -25°C~+55°C; +70°C is allowed only in short time (not more than 24h); all devices can work normally under normal conditions and cannot have irreparable damages at limit temperatures
5. Please consult us if clients have other different conditions
