* input current: <20A @2900W/176Vac           

* starting current: <32A           

* rated input frequency: 50Hz/60Hz           

* output DC voltage range: 42V~58V           

* output DC current: 0A~65.5A           

* regulation accuracy: less than or equal to 0.5%.           

* load adjustment rate: less than or equal to 0.5%           

* voltage adjustment rate: less than or equal to 0.1%.           

* power factor: greater than or equal to 0.90 (@25%~50% rated output power).           

                        More than 0.90 (@50%~100% rated output power)          

                        More than 0.99 (@50%~100% rated output power)           

* efficiency: greater than or equal to 91%           

* over voltage protection: input under voltage protection point 80 + 5Vac input overvoltage protection point 305V + 5Vac           

* Output Overvoltage Hardware Protection Point: 58.5-59.5V (Output Overvoltage Software Protection Point 56V-59V can be set by monitoring)           

* module current sharing error: less than + 0.9A           

* cooling mode: forced air cooling.           

* safety standards: UL/EN/IEC 60950-2000           

* safety requirements: CE/UL/NEBS           

* outline size: 87.9mm (high) X85.3mm (wide) X272mm (deep)           

* module weight: ≤4kg

 Lead time:
We have a lot of stock ,If the quantity isn't very big , we can send the goods as soon as possible after recieve payment.If big quanity, the lead time need according to the quantity. 
Transporting:
If small quantity, usually send by courier (DHL,FEDEX,TNT and so on) . If big quantity, we advice ship by air or by sea. this will use longer time ,but cheaper fees. We are near the port of TianJin.
Our service:
We can offer the sample. If the quality is good, we can offer very very competitive price .And can pack according to customer's requirment.

1. Could i put my own logo on it? 

> Sure, of course,we have over 18 years OEM experience,customers' logo can be made by laser, engraved, embossed, transfer printing etc. 

2. Should i pay extra for logo printing ?
> If you order amount over out MOQ for OEM package,all OEM fees would be free,if you want to make a trial order,we need to charge a very little fees for the printing and cartons.

3. How about the quality?

We import DU POND brand PA66 nylon raw material from USA,we make sure good quality from the most important factor.
> Acquire the CE & FDA Certification.
> 100% QC in produce process and before package.

4. Could i buy 1pc sample first and small order ?
> Of course, support sample order and small order, especially for new customers under certain condition.

5. How much for 1pc sample ?
> we will send 1 bag for free

6. If i have my thoughts, do you have person to design according to my concept?
> Certainly,our design team is willing to do for you.

7. How long to make a sample? 
> 3days which depends on the samples' complexity.
