• Convenient maintenance: power unit uses handcart style installed cabinet structure, which is convenient for dismantling and installment, and it can bed configured with maintenance tools, and shorten maintenance time significantly;
• Strong anti-EMC capacity: power unit and control unit are separable, and it is convenient for frequency inverter to form cabinet and anti-interference capacity is strong; 
• Strong heat dissipation capacity: use bottom blowing cooling method of centrifugal turbine blower, copper board radiator structure, and cooling efficiency is higher; 
• Flexible power unit configuration: it can realize big capacity output in parallel with power unit, and improve equipment interchanging property, and spare parts are less;
• The device is configured with operation panel, and support Chinese interface, which can be installed in transmission cabinet door flexibly;
• Frequency inverter is superimposition of rectification module and inverter, which is easy for replacement and convenient for maintenance.
• Strong control performance: use imported core controller and guarantee complete realization of control function of its frequency inverter;
• Wide application range: the performance of frequency inverter is strong, which can satisfy various use working status;
•  
•  

Applications:

lifting and hoisting machinery, such as hoisting, lifting, cart, swinging gear.
