How to select power transformer

First, when choosing a power transformer, first consider the capacity of the power transformer, and then consider other factors.

Second, the selection principle of power transformer:

The principle of choosing a power transformer is to choose according to the voltage level of the equipment, the power of the transformer and the operating temperature of the equipment. This is because different equipment has different voltage requirements, if the selected transformer voltage is different, it will lead to equipment failure.

Third, how to choose the right power transformer?

When choosing a power transformer, the first thing to consider is the voltage of the power transformer. The input and output of the power transformer are AC voltage, and the second thing to consider is the power specification of the power transformer. According to the voltage and current requirements of the equipment, select the appropriate power transformer specifications. The last thing to consider is the size and weight of the power transformer. Select the appropriate size and weight of the power transformer according to the installation space and needs of the device.

1. Power selection: Because the transformer is a power type device, it will generate a certain amount of heat when working. Select the corresponding transformer according to the actual application scenario.

Choosing the right power transformer can ensure the stability and output power of the power supply. If you choose the wrong power transformer, it may cause problems with the power supply.

2. Transformer output voltage:

No-load voltage: generally 10%~12% higher than the nominal voltage, for example, nominal 12V, the actual no-load =12V+12V*0.1=13.2V

Nominal 24V, actual no-load =24V+24V*0.12=26.88V

Load voltage: As the load increases, the output voltage will decrease, and the size of the load is inversely proportional to the output voltage.
