Mean Well provides a derating curve in the datasheet, but it's not explicitly stated. However, according to Mean Well's application notes, the derating curve for the LDH-45B-1050W is approximately 2.5% per degree Celsius above 40°C.
Yes, but with some limitations. Mean Well recommends derating the power supply by 1% for every 100 meters above 2,000 meters. Additionally, the power supply may require additional cooling or heat sinking to ensure reliable operation.
According to Mean Well's reliability report, the MTBF for the LDH-45B-1050W is approximately 550,000 hours at 25°C, calculated according to MIL-HDBK-217F.
Yes, the LDH-45B-1050W can be used in a redundant configuration, but it requires additional circuitry and design considerations to ensure proper operation. Mean Well recommends consulting their application notes and seeking guidance from a qualified engineer.
Mean Well recommends keeping the DC output cables as short as possible, but the maximum recommended length is approximately 1 meter. Longer cables may cause voltage drops and affect the power supply's performance.
