Programmed Helicopter RC Charger SMPS Battery Charger 13A 30V 400W
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.

Advantage
Two core technology
Chargery Profile
From 2006, we focus on developing high power (up to 60A 3000W) charger, balance charger (AC input, DC input and AC/DC dual input) and 800A BMS for up to 24S LiPo/LiFe/ LiTO battery.
Chargery charger can charge any chemical battery including LiPo, LiFe, Li-ion, LiTo, NiMh, NiCD and Pb (Lead acid, VRLA battery), cell count, charge current, end voltage and end current can be programmed. and realize anti-spark and reverse polarity protection when high voltage battery connect to charger or inverter(loader).
Chargery BMS can handle up to 800A charge and discharge current, special designed DCC (DC contactor) is built-in surge suppressing circuit.
Operation

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.
