Performance Characteristic
1. C-class insulation (one level higher than H-class insulation), excellent heat dissipation conditions, great overload capacity, 130% overload without the need to put in a fan can be long-term safe and stable operation; under IP45 conditions, no forced air cooling is required and it can still operate safely and stably for a long time.
2. Extremely high safety and flame retardant performance, long-term combustion at 800℃ high temperature without smoke generation.
3. Strong ability to withstand thermal shock (can be fully loaded immediately at -50℃).
4. 100% waterproof sealing.
5. No partial discharge.
6. Dirt and water repellent, can withstand acid and alkali corrosion and fungal or mold invasion.
7. Environmental protection concept - low noise, no harmful gas, no pollution to the environment, easy to decompose and collect after life, protect the environment, in line with the trend.
