1. How could I get samples?

We offer the samples of our products, such as frequency inverter, variable speed drive, servo motor and drive, motor soft starter... All the samples are charged. Usually, the sample price will be higher than the wholesale price.   

If you want to order the samples, we will calculate the sample cost and courier cost for you. If you have any courier account, the courier cost can be collected in your side. After your confirmation, we will prepare the proforma invoice.

For sample order, we prefer to accept payment by Western Union, MoneyGram. If you like to use T/T wire transfer, please pay both the bank charge in your side.

2.How much of the courier freight will be for the samples?

The courier freight depends on the quantity, weight, carton measurement and your area.

3. How can I get your price list?

If you are interested in some models and would like to know the price, please let us know the model number and your possible order quantity. Then we can quote you the better price for that quantity.

If you need a whole price list of all models for reference, you can contact us by email .

The transportation way depends on your choice. And the freight depends on quantity, weight, volume, transportation way, destination country (the international airport, sea port).

8. What's your usual payment term for orders?

Knowledge for frequency inverter, VSD, motor softstarter, servomotor, servo drive, EMI filter:

1. What's frequency converter?

The term Frequency Converter is interchangeable with AC Power Source and AC Power Supply. Frequency Converter describes a black box that will accept one form of AC voltage input at a certain frequency and will convert that input to a desired AC voltage and frequency at the output. You can change voltage with a transformer or variac, but to change frequency you need a frequency converter (AC power source).

2. What is a variable speed AC drive?

AC drives control the speed of either an induction motor or a synchronous motor by adjusting the frequency of the power supplied to the motor. AC drives are also known as adjustable speed drives (ASD) or adjustable frequency drives (AFD) or variable frequency drives (VFD) or variable speed drives (VSD) or frequency converters (FC).

3. Why use AC drives (Frequency Inverter, AC drive inverter, variable voltage variable frequency drive, VVVF drive)?

Process control and energy conservation are the main functions.
Saving energy by using AC drives (frequency converter, VVVF drive).
Adjusting speed as a means of controlling a process.

AC Drives improve Speed Control and Energy Efficiency
