PS550-L series is the dedicated integrated machine for construction hoist. The use of variable frequency speed control technology can realize the start-up acceleration and deceleration of the construction elevator and the stepless speed variation in the process of braking, reducing the impact of the motor on the mechanical system during the shutdown and improving the smoothness and comfort during the operation of the construction elevator. It extends the service life of the construction elevator and greatly improves the work efficiency.

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%.

7)Altitude

8)The use of flammable, flammable, explosive gas, liquid or solid hazardous environments is prohibited.
