Used the transformer. SO will be change 40vdc.

Humm (no pun intended) - a DC transformer, must be something new in the market. A variable potentiometer will allow you to reduce the voltage to the required voltage you need. It will have to be of a higher wattage variety to dissipate the heat that will be generated depending on the wattage of the load at 40 volts.

∙ 12y agoFor an AC supply, you can use a transformer.
For a DC supply, you can use a voltage-divider. In the simplest case, this comprises a pair of resistors, of appropriate value, placed in series with each other, but in parallel with the supply. The load is then connected in parallel with one of the resistors. Basically, the value of each resistor must be such that one resistor has a voltage drop of 48 V across it, and it is across this resistor that the load is connected. The actual calculation to determine the resistance of each resistor is rather more complicated, as you need to take the resistance of the load into account, too -but this is beyond the scope of this answer.

∙ 11y agoFor an AC voltage you would use a 4:1 step-down transformer rated adequately for the necessary power dissipation.
For a DC voltage you would use a solid-state voltage regulator or a two-resistor voltage divider (having a ratio of 3:1) and taking the output voltage from between the two.

Why be use the -48 volt for bts?
48 is volt scale and negative voltage is used for safety of media, to prevent attanuation and noise.
How many volts to run a 48 Volt club car electric motor?
If a 48 Volt club car electric motor requires 48 volts, then it should be given a 48 volt power source, or something close to it. Too many more volts and it may burn out; not enough volts and it may not run or it will try to draw too much power and burn out the power supply.
How do you increase Speed on a Yamaha 48 volt golf cart?
You can increase the speed of an Yamaha 48 volt golf cart by installing a larger motor or more powerful batteries. This will produce more power to the wheels and more speed.
What can a 48 volt power supply be used for?
A lot of commercial telecommunications equipment runs on 48 volts. There are also relays that use 48 volts. I'm sure there are many other uses for this. I'm not aware of any in a typical house, if that's what you're looking for. Perhaps certain water softeners, sprinkler systems, etc. run on 48, but the ones I've seen usually run on 12.
What is the gcd of 84 and 48?
The Greatest Common Divisor (GCD) for 84 48 is 12
How do you install 12 volt lights on 48 volt cart?
If your cart has 4, 12 volt batteries in series to make up the 48 volts, just connect the 12 volt lights across one of the batteries.
Can you use a 12 volt battery to charge a 48 volt battery?
No
How do you link 12 volt batteries to get 48 volts?
You must hook them up in series. You will need four 12 volt batteries to do this.
How is -48V possible in telecomm equipment?
Voltage is dependent on a reference. If I have a 12 volt battery, and ground the - side, it is 12 volts to ground. If I instead ground the + side, it is -12 volts to ground. -48 volt telecom equipment is simply referenced to ground "upside down" or backwards, giving it a negative sign.
What is the resistance of the 12 volt circuit and has a measured current 0.25 A?
R = E/I = 12/0.25 = 48 Ω
Can you parallel 4 sets of 6 volt batteries to get 12volts at the same time having the same batteries in series for a 48 volt laod?
Paralleling four sets of 6 volt batteries will still give you 6 volts. Two 6 volt batteries in series will give you 12 volts. Parallel these series sets will give you longer endurance at 12 volts. There is no way you will ever get 48 volts out of four 6 volt batteries.
Can a 36 volt battery charger charge a 48 volt system?
No.
Up grade 36 volt golf cart to 48 volts?
You will have to change the cart motor to one that operates on 48 volts DC and then add one more 12 volt battery (identical to the exsisting) in series with the batteries that are in the cart now.
How long does a stock 12 volt car battery last?
Now adays about 36 - 48 months is all you get from one.
Join 4 12 volt batteries for 48 volt output?
Yes, In series connection with -ve to +ve for each terminals or vice versa.e.g. suppose the batteries are like -Battery1+Connect them as (-Battery1+)+(-Battery2+)+(-Battery3+)+(-Battery4+) will give you 48 Volts.
Why be use the -48 volt for bts?
48 is volt scale and negative voltage is used for safety of media, to prevent attanuation and noise.
When you link 4 batteries of 12volts for a 48 volt system why dont you use 1 battery of 24 cells?
If you have a 48 volt system, you link 4 batteries of 12 volts to get 48 volts. You do that because it is extremely easy to get 4 batteries of 12 volts. It is extremely difficult to find a store that sells a 48 volt battery. Most people with battery problems would prefer to simply replace the batteries and be on their way rather than stay in a motel and then pay overnight shipping fees to have a particular battery shipped from a particular warehouse.
