Power calculation method

first, without magnetic amplification technology, the calculation of this power supply is relatively complex (version 1.3 power supply)

the output of the switching transformer of this power supply is +3.3v+ 5V +12v shares one winding of the transformer. These three groups of currents affect each other, so they are at +3.3v+ The maximum

output power cannot be reached at the same time in 5V +12v. Therefore, the maximum power corresponding to these three groups of voltages cannot be accumulated To get the power

his calculation method is

p rated =u * i+5v current

in this formula, u is a variable voltage value. It is estimated that the value can be between 10~11.5v, and it is appropriate to take the minimum value when estimating The unit of u is V, the unit of I +5v maximum current output is a a

pmax =r* P rated

where R is a proportional variable, which can be taken between 1.15 and 1.25 when estimating, and the minimum value is still appropriate when estimating

for example:

the voltage and current of each group of this power supply is

+3.3v14a +5v21a +12v10a letter

the maximum current of +5v above is 21a, and the P rating brought into the above =u i+5v current

that is, P rated power =10x21=210w

P maximum power =1.15x210w=241.5w

so the rated power of this power supply is 210W. If you don't know how to calculate, you will choose the above groups in winter and summer.How to do it? A: add up the power of each group of current with the air conditioning voltage x, and there are many elements to think about how to sort the query effect, that is, about 300W, This is the reason why fake 300W is popular in the market

2) wedging effect of fulcrum: when the beam is under load, the second is the calculation of power supply power using magnetic amplification technology (version 2.0 version 2.03)

his calculation method is

[p rated power = the cumulative sum of voltage x current of each group

p maximum power =p rated power *r (r=1.13d the printed object has a smooth and high-quality surface 5~1.25)
