I want to make a DC adapter which outputs 13.5V 6AMP

AI Thread Summary
The discussion focuses on creating a DC adapter with specifications of 13.5V and 6A output, suitable for 240V input. Participants emphasize the importance of adhering to safety regulations when working with AC mains voltages, suggesting that a transformer-based solution may not meet the desired output specifications. A switching regulator is recommended as a potential solution, though it introduces additional design complexities. The existence of similar power supplies available in other regions, such as the TEAC 66-135000V model, is noted, indicating that alternatives may be accessible. The user expresses interest in finding a suitable adapter available in India while questioning the impact of a 1 amp difference in output.

Any links or suggestions would be really helpful. I have a basic understanding about transformers, bridge rectifier & capacitor. I need help in shopping what transformer, diodes & capacitors should i buy. I tried to search online but couldn't find any. Adapter Specs IN> AC:100v-240v OUT> DC:13.5v 6AMP.
What I'm trying to make is

for 240V input instead 120V IN.

Thanks..

Welcome to the PF.

Can you tell us what safety regulations apply to the AC Mains side of the adapter? Are you going to build it to UL safety specs, or TUV, or some other agency's safety specs? Working with AC Mains voltages is dangerous, so it's important that you understand the construction techniques that are required at the input section for the switch and transformer.

Also, your specs, "IN> AC:100v-240v OUT> DC:13.5v 6AMP" are not achievable with a transformer-based adapter. You would need to make a switching regulator to accomplish those specs, and that involves even more design issues...

Well,
I have about safety regulations But I'm certain that AC mains gives out 240V. What I'm trying to make is one of these http://www.faylist.com/allliquidation/adapters/creative_ua1460_ac_adapter.htm
But this one takes 120 V input & its not available in India. I want to make one as i specified above.

Creatiive certainly sell similar power supplies that run on 240V. I've got one sitting next to my PC right now in the UK. Model Number TEAC 66-135000V. 230V in, 13.5V 5A out. It looks the same as your picture.

Your specification "IN> AC:100v-240" means it will work on either 120 or 240V mains.

I don't know if there are any issues about them being unavailable in India, though.

Cool Thanks. I wonder how much difference would 1 amp make. I'll try to find if it is available here.
 

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...
