1.Most failures are caused by environment, motor (insulation), power supply, and some incorrect operatios etc.
2.When the inverter works under normal conditions,the failure rate is less than 0.7%.

Of course.
When the quantity is good,we can provide OEM service for our customers.
We will help our customers to add their own logo on the products and related documents like manual and certificate.

Our standard inverter has 320Hz maximum output frequency.
For special application,like high speed spindle,we can provide special inverter with 3200Hz maximum output frequency.

We provide 24 months warranty to our distributors.
During warranty period,when failure occurs which caused by products quality,necesasry spare parts would be provided. The spare parts are free of charge.

Yes,in some countries,the tarif for the whole products is high but for SKD products,it can be low.
In our company,the inverter with power less than 22KW,we can split it to many parts,like keyboard,control board,power board and so on.

Running environment temperature is between – 10℃ ~ + 40℃.
If the temperature is between 40℃~ 50℃,please using the inverter de-rated.
The installation site should be free from oil mist, corrosive flammable gas, no radioactive material, metal dust, dust, oil, water and other foreign objects.

We have two main series inverter for choose.
Different voltage level has different power range.
For 380V/415V voltage grade,the power range is 0.75KW to 630KW.
Single phase 230V input and three phase 0~230V output inverter,power range is 0.4KW to 30KW.
3PH 230V input and 0~230V output,power range is 0.4KW to 185KW.
If you have special requirements of power and voltage,please sent inquiry to us.

We have two main series now,SV600 Series Universal vector inverter and SV800 intelligent vector inverter.
Single phase 230V,3PH 230V,3PH 380V/415V, 3PH 480V voltage grade available.
Also some non-standard inverter can be selected.

The model name with ‘B’ mark has built-in braking unit.
For more details,please refer to our manual.

When large load connects to the power supply(normally transformer),the supply voltage may decrease.
So the inverter in the same power supply grid will report undervoltage and stop.

Of course.
On our inverter nameplate,it has 50/60Hz mark which means 50Hz or 60Hz both available.
Actually our inverter can accept 47-63Hz power supply.

For standard inverter,the output voltage range is 0-input voltage.
If you really need 1PH 230V input but 3PH 380V output inverter,please contact with us.
We need to design special inverter for you.

Different series inverter has different control mode for choose.
SV800 supports V/F control,open-loop vector control(SVC), close-loop vector control.
SV600 supports V/F control,open-loop vector control(SVC).

Different power has different energy consume.
About 5%.
