Equiped with the protection devices for over-current, short circuit and u ndervoltage, the products are capable of preventing damage of circuits and supply units. The products conforms to GB/T14048.2, IEC60947-2 stardands.
Normal Operating Conditions
Altitude: ≤2000m
Installation height 2000m ~ 5000m can be specially customized. The product needs to reduce the capacity to use.
Pollution Degree: 3 according to IEC 60947-1
Ambient Temp. (operating): -5 to 40 ℃
For the working conditions of -40~-5℃ ambient temperature, please inform us when ordering.
When the ambient temperature is higher than 40 ° C, the product should be used at reduced capacity.
Ambient Temp. (storage): -40 to 70 ℃
The average ambient temp. in 24 hours cannot exceed 35 ℃.
The relative humidity cannot exceed 50% @+40 ℃. A lower temperature can have a higher humidity. The relative humidity can reach 90% at 20 ℃, and corresponding measures should be taken for the condensation frost caused by the temperature change.
