Precautions for inverter use environment
The supplier of the brake unit reminds you that the inverter cannot be used normally under any circumstances, so it is necessary for the user to have more knowledge about the load, environmental requirements and the inverter. The use environment of the inverter cannot be ignored to ensure the safe and reliable operation of the inverter, so that the inverter and the equipment it drives can give full play to its best performance, extend the service life of the inverter and the equipment, and reduce the occurrence of accidents.
1. The influence of temperature on the inverter
When selecting the inverter, it should be considered that the operating environment temperature is generally -10～40℃. If the temperature of the working environment is higher than 40℃, the inverter should be derated by 5% for every increase of 1℃; When the temperature rises by 10°C, the life of the inverter will be halved, so the surrounding environment and the problem of inverter heat dissipation must be solved.
2. The influence of humidity on the inverter
When selecting the inverter, if it works in an environment with a humidity lower than 90%, the relative humidity of the air is lower than or equal to 90%, and there is no condensation. If the humidity is too high and the humidity change is relatively large, condensation is more likely to occur inside the inverter, then the insulation performance will be greatly reduced, and even a short circuit will occur. When necessary, a desiccant or heater must be added to the box.
3. The influence of altitude on the inverter
The inverter can output rated power when installed at an altitude of less than 1000m. When the altitude exceeds 1000m, its output power will decrease.
4. The influence of dust on the inverter
In the occasions with metallic conductive dust, it is not suitable to install the inverter. Because conductive dust will invade the inside of the inverter, it is easy to short-circuit the internal circuit of the inverter, and in severe cases, it will burn the inverter. Inverter maintenance expert Tongyida reminds everyone to think of this when selecting inverters.
