30V 400W adjustable voltage current Switching power supply Low noise SMPS 13.5A 30V

30V 400W adjustable voltage current Switching Power Supply Compact 55mm Low noise SMPS 13.5A 30V

The S400 is a PFC-programmed SMPS that can deliver an output of 13.5A at 10V-30V, and 400W at AC90V~265V, all within a compact size. Innovative technologies have been employed in the SMPS, enabling it to achieve up to 92% efficiency while maintaining a temperature below 95℃. Its design is compact at only 55mm, and operates with low noise thanks to a cooling fan that is controlled by temperature.

Features

• Intelligent control output voltage and current by microprocessor,
• Active PFC: smaller AC input current less interference, and Conform to European Commission Regulation no 278/2009 and Energy Star Version 2.0
• AC100-240V worldwide use: need not any alternative switcher, worldwide safe operation
• Up to 92% of convert efficiency
• Programming output voltage from 10 to 30V, suitable for more application
• Digital LED display output voltage and current on time
• Over current, over voltage, over load and over temperature protection, and resume automatically
• Short-circuit protection on output, safer and more reliable
• Intelligent cooling fans turned on at over 45℃ and increase speed with the temperature going up.
• Synchronous Rectification make sure the high efficiency and smaller size

FAQ

Q1. Can I have a sample order for SMPS?

A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable.

Q2. What about the lead time?

A: 3-5 days for Sample preparing, 5 -10 working days for mass production.

Q3. Do you have any MOQ limit for OEM order?

A: Low MOQ, 1pc for sample checking is available.

Q4. How do you ship the goods and how long does it take to arrive?

A: Ship by DHL, UPS, FedEx or TNT. It takes 3-5 days to arrive. Airline and sea shipping also optional.

Q5. How to proceed an order for SMPS?

A: Firstly let us know your requirements or application.

Secondly We quote according to your requirements or our suggestions.

Thirdly you confirm the samples and places deposit for formal order.

Fourthly We arrange the production.

Q6. Is it OK to print my logo on SMPS product?

A: Yes. Please inform us formally before our production.

Q7. Do you offer guarantee for the products?

A: Yes, we offer 2 years warranty to our products.

Q8. How to deal with the faulty?

A: Firstly, Our products are produced in strict quality control system and the defective rate will be less than 0.2%.

Secondly, during the guarantee period, we will send new lights with new order for small quantity. For defective batch products, we will repair them and resend them to you or we can discuss the solution including re-call according to real situation.

Q9. Why the voltage and current reading on LED is not accurate?

A: voltage and current is very sensitive due to their small value, so please check the output wire connection, when distance between the SMPS and your device is a problem, please lengthen AC cable NOT lengthen DC cable (output cable). the 1.2 meter (16AWG) output cable length is suggested, over 1.2 meter, will affect voltage and current accuracy especialy at 13.5A.
