To ensure optimal performance and extended service life, the following operating conditions are recommended for Comewill JDZ10-3/6/10A Voltage Transformer:
Altitude: Suitable for installation up to 3,000 meters above sea level, with stable operation in high-altitude areas without special modifications.
Ambient Temperature: Operating temperature range of -5°C to +40°C to prevent insulation degradation and accuracy deviation.
Relative Humidity: Maximum 65% at 20°C to avoid moisture-induced aging of internal components.
Pollution Level: Designed for Class II pollution environments, capable of handling minor indoor or outdoor contamination.
Installation Environment: Should be free from corrosive gases to protect the casing and internal windings.
If the installation environment on your end is special (such as high humidity and corrosive gases), you can communicate in advance to customize an adaptation plan!
