PI500-W series frequency inverter for constant pressure pump
Dalian Powtran Technology Co., Ltd.
The water supply system is an important and indispensable part of production and life,The traditional water supply method covers a large area,the water quality is easy to pollute,the infrastructrue investment is large,and the main disadvantage is that the water pressure cannot be kept constant resulting in some devices not working properly,As the variable-frequency technology matures,variable-frequency constant-pressure water supply equipment fundamentally solved these problems.With advanced technology,constant water pressure,easy operating,reliable operation.energy saving and high degree of automation,the variable-frequency constant-pressure water supply technology has been widely used in various industries.
1. Environment temperature -10 ℃ to 50 ℃, temperature at 40 ℃, please derating for use, derating at 3% per 1°C drop. It is not recommended to use the inverter in the environment above 50°C.
2. Prevent electromagnetic interference and keep away from sources of interference.
3. Prevent intrusion of the water droplets, steam, dust, dust, cotton wool, and metal fines.
4. Prevent intrusion of the oil, salt, and corrosive gases.
5. Avoid vibrations. The maximum amplitude can’t exceed 5.9m/s (0.6g).
6. Avoid high temperature and humidity and no rain. Relative humidity is less than 90%RH. Do not allow condensation. In spaces where corrosive gases are present, the maximum relative humidity can’t exceed 60%.
