    Tips: ATO 500VA-10kVA control transformers working environment

    1. Ambient air temperature: -5℃~+40℃, the highest monthly mean temperature should not exceed +30℃.
    2. Altitude for installing place should not exceed 1000m.
    3. When the ambient air temperature is +40℃, the relative humidity should not exceed 50%, and it allows higher relative humidity under lower temperature. Max average humidity in the dampest month is 90%, meanwhile the lowest average temperature of this month is +25℃, and condensation on the product surface caused by temperature change should be taken into consideration.
    Existing reviews of 500VA Control Transformer, 240V to 110/36/24V
