FAQ

Q 1. What is the payment term?
A. We accept T/T (30% deposit, balance before shipment) or L/C 100% at sight or other workable methods.

Q 2. How long is the production lead time?
A. Usually it takes about 10-35days.  For sample order, it usually takes 4 weeks.

Q 3. How do you pack the products?
Firstly, wrapping with plastic film, them cover with polybag, packed with export wooden case.

Q 4. What materials are used in transformers?
A. We have two types according to your requirement. One is 100% copper, the other one is copper with aluminum. Please be noted that the cost is different for each type.

Q 5. Do you provide Form A or C/O?
A. Yes, please contact us if you need.

Q 6. Do you accept to use our logo?
A. Yes, we accept OEM order if there's large quantity. However, we'll be appreciated if you use our HOWAPOWER logo, and we will give a little discount to support.

Q 7. What is your MOQ?
A. Small capacity products below 30KVA, the MOQ is usually10 units; For large capacity products above 50KVA, the MOQ can be 1 unit.

Q 8. Where is your market?
A. Our products are sold well in many countries around the world. We look forward to our further cooperation.

Q 9. What kind of certificate do you have ?
A. We've already obtained CE, ISO9001,TUV and technical patent certificates.

Q10. How can I get your best price?
Please let us know more details of your company.

Q11. What is your warranty? 
Two years warranty.

Q12. What is the advantage of your AVR?
We use our patent split current voltage control design, More efficiency and smarter.
Compact design could suitable for small spaces. Up to save 25% spaces for user.

Q13. What is the output accuracy? 
Normally factory set as ±2%,but can be customize from ±0.5% to ±5%.

Q14. What's the means of the input voltage range/window of the voltage stabilizer?
For example, A ±20% input voltage range/window and 400V rated voltage of voltage stabilizer, the voltage stabilizer could deliver 400V output constantly when input voltage within 400V±20%(320V~480V), If the input voltage under 320V, The output voltage will under 400V and if the input voltage over 480V, the output voltage will over 400V as well. It's a very important parameter that the user should be considered.

Q15. What is the input range/window of your voltage stabilizer?
It's an option, we have standard ±15%, ±20%, ±25%, ±30% models for choice, and others can be customized.

Q16. How to select a suitable capacity voltage stabilizer?
Check your maximum current and give a 20% margin is best.
For example, electric furnace is about 250kVA, please choose more than 350kVA voltage stabilizer.

Q17. What's the rated current of the voltage stabilizer?
Rated current= KVA/1.732/V rated,  V rated means the rated voltage of this unit.

Q18.What is the difference between your stabilizer and others?
1. Split current voltage control technologies, Heavy loading capacity, Up to 0.5% output accuracy.
2. Independent phase regulation, three phase output voltage will be more balance.
3. Our unique technical design makes unique compact dimension, our cabinet can save 25% space than traditional one.
4. 200% over load with 10secs, 150% overload with 60secs,120% overload 10mins.
5. The H class wire, Temperature resistance up to 180ºC
6. Non combustible silicone wire to be use, More safe.
7. Standard full bypass design, Easy for maintenance.
8. 7" Touch HMI, all parameters showing clearly and Two Security password to protect the parameters.
9. All big brand components, such as Fuji brand contactor, Chint brand breakers, More reliable.
10. Full protect with Under/Over voltage protect, Over load protect, Phase lost protect and so on.

Q19.What is your annual production capacity?  Can you tell me your sales amount of last year?
OEM+ODM turnover 20million plus. Production staff 20 plus. QC staff 5 plus, Research department 5plus and sales department 5 plus.

Q20. How to solve it if have some quality problems?
Based on the steps of analysis, and conclude the key reason of the problem. Usually, we will provide spare part free of charge during warranty time.

Q21. Normally, how long is the work life of the machine?
With proper preventive maintenance, our machine can last for more than 15 years.

Q22. what's the largest capacity your company can manufacture?
Up to 3000KVA, and it occupies only 2 cabinets.

Q23. During the installation of the machine, do we have to get the electrical license?
Normally he must know electrical knowledge, no matter got license or not, we have very detailed instruction manual.

Q24. Why their protections shall set on 0.8 x FLA (full load ampere) - isn't the product capable of delivering full capacity?
Every product is not good to be use in full capacity, such as the Car. We can drive the car in full speed when the driver is the best and the road is best too. The same as the AVR, We should give a best environment then the AVR could delivering full capacity. Such as the Ambient temperature, altitude, humidity, Air ventilation and dust-free are best. If not, we can't let AVR delivering full capacity, So we give a 20% for margin.

Q25. How you are supposed to get periodical preventive maintenance service?
After every 6 to 12 months of operation, the AVR must be cleaned from dust and carbon powder. Pay attention to the brush surface and the autotransformer surface where the brushes are touching. Clean it with soft brush or dry cloth.
It is also essential to lubricate the gear and the drive parts with a small amount of lubricant oil every regular interval.
Inspect the mechanical fasteners and tighten any loose screws. The three brush groups should be on one level line.
