The operating temperature and humidity range of the load bank will vary depending on the type, application scenario and manufacturer. The following introduces the common range for you:

Operating temperature range

• General industrial load bank:

The common operating temperature range is 0℃ - 40℃. Within this temperature range, the components of the load bank can operate stably to ensure the test accuracy and equipment performance. For example, the load banks used for testing equipment such as ordinary motors and inverters are mostly in this temperature range. When the temperature is lower than 0℃, the characteristics of some electronic components may change, affecting the performance of the load bank; higher than 40℃, it may cause equipment heat dissipation difficulties, causing internal components to overheat, shortening service life, and even causing failures.

• Special load banks for high temperature environments:

Some special industrial scenarios require equipment to be tested in a high temperature environment. Such load banks can work in an environment of 50℃ - 85℃. Equipment testing in high-temperature production workshops such as steel and cement requires high-temperature load banks. They use special heat dissipation design, high-temperature resistant materials and electronic components to ensure stable operation at high temperatures.

• Special load bank for low temperature environment:

suitable for testing outdoor equipment in cold areas or products with requirements for low temperature performance, the operating temperature range can be as low as -40℃ - 0℃. For electrical equipment used in low temperature areas such as polar regions and high mountains, it is necessary to simulate low temperature working conditions with a special load bank for low temperature environment. This type of load bank has good insulation measures and cold-resistant components to prevent equipment damage at low temperatures and ensure normal operation.

Working humidity range

• Ordinary load bank:

The relative humidity range is generally 20% - 80% (no condensation). A moderate humidity environment can ensure the normal operation of electronic components and metal parts inside the load bank. Too high humidity can easily cause components to short-circuit due to moisture and metal to rust and corrode; too low humidity may generate static electricity and affect the normal operation of the equipment.

• Moisture-proof load bank

used in high humidity or humid environments (such as coastal areas and humid basements), the relative humidity range can reach 90% - 95% (no condensation). This type of load bank uses special moisture-proof design and materials, such as sealed banks, moisture-proof coatings, waterproof electronic components, etc., to avoid humidity affecting equipment performance and life.
