AC inverter with excellent quality and enjoying high
reputation in international market.

We have a series of space vector inverter from 8 bit to 16 bit

with complete specification and models, with very strong
function and easy operation, small size... etc features for 

industry needed. Thus, it is very wide popular on markets.
Long Shenq Electronic Co.,Ltd.
has very excellent development capbility.

Except for current general type inverter,
we have successful developed build-in inverter,
motor type inverter (installed inverter to motor),

for sporting equipment. 

All these models,we are mass producing and  receiving order
from customers.
Also, we have made these inverters for famous companies  
by OEM cooperation.

Except for inverter endeavor, we are outstanding in relative equipment.
For example, 220V and 380V/440V specialized braking unit. 
It is best selection for inverter example.
Also, it is indicated by many Japen brands to use.

Now,we are standard products as following;
