Three phases 440 volt 60hz to Three phases 400 volt 50hz converter

Product Description

Three phases 440 volt 60hz to Three phases 400 volt 50hz converter

Three phases 440 volt 60hz to Three phases 400 volt 50hz converter is the most advanced AC to DC to AC type converter products, which is characterized by multi function, stable and reliable performance, set up parameters flexibly, easy for maintenance and long service life 15 to 20 years. It can meet different user different requirements

Three phases 440 volt 60hz to Three phases 400 volt 50hz converter Advantages:

• Easy to repair

Adopted Japanese Mitsubishi IPM intelligent module, Modular and simple structure design, very easy and convenient for maintenance, any fault only need us send you parts for replacement, maintenance is low skill work   

• Little fault rate 

It with powerful protection function for short circuit, over load and over temperature which is more safe and reliable. Fault rate < 1%

• 100% full power stable output 

Inside with full power low frequency isolated transformer, 100% full power output, can work 24hx7, which ensure the AC busbar and DC busbar are completely isolated, the harmonic and interference is very little, constant voltage and constant frequency stable output. And the accuracy of output voltage is very high less than 1%. 

• High efficiency  

> 92%

• Long service life 

> 15 years

• Setting flexible

The output frequency 50Hz or 60Hz can be set. 

The output voltage can be set. 

• Two kinds of start mode

Variable Frequency Start or Step Down Voltage Start

With higher capacity to drive motor inductive load, save the cost of soft starter

• Big LCD display

Display real time running parameters, easy operation
