Can we use 50 Hz transformer on 60Hz?

It can work, in fact, the transformer is usable in circuits ranging from 45Hz to 60Hz. The transformer 50/60Hz is widely accepted to be universal in use. The materials are the same, but there is a variation in the number of turns. Transformer coils operating at a power supply frequency of 50Hz require a little more per volt than those that operate at a power supply frequency of 60Hz. Thus, we find that the cores of both transformers are exactly the same…

Encapsulated Transformer PCB Mount Function

Vacuum potting fix the lamination steel and bobbin, and at the same time, ensure that the transformer will not corrode when placed in the air for a long time. It is perfect for applications in harsh environments, where dust, lint, moisture and corrosive contaminants can accumulate.

Why high frequency transformers are small?

Since traditional transformers can’t meet today’s efficiency requirements, high-frequency transformers were invented. High-frequency transformers improve efficiency, as well as save power, and have a longer service life than standard transformers.

What is the difference between a step-up transformer and a step-down transformer

The basic principles of step-up transformer and step-down transformer are the same.The main difference between a step-up transformer and a step-down transformer is their performance during their operation. The step-up transformer is designed to increase the output value, while the step-down transformer is designed to decrease it. Here, we discuss the differences between step-up transformers and step-down transformers, including definition, voltage,windings, conductor sizes, magnetic fields, and applications.

How to select lamination for transformer ?

Lamination material for transformers is silicon steel, silicon steel is a kind of steel containing silicon (silicon is also called silicon), and its silicon content is between 0.8% and 4.8%. Silicon steel has the characteristics of high magnetic flux, low iron loss, low temperature rise, low no-load current, low noise, etc. The silicon steel can generate a large magnetic induction intensity in the energized coil.

What is the Flyback Transformers?

A transformer works in the flyback circuit, the output and input of the secondary transformer are reversed. The transformer’s magnetic core stores energy during operation, so the magnetic density is higher than other methods, the flyback transformer has a much lower power rating.

How to choose the correct bobbin for power supply transformer?

You must first determine the size of the power transformer to be designed, and then calculate the core AE area by using a formula or experience, and finally determine the type of core.
It is important to know the position of the transformer in the pcb, otherwise the designed transformer is too large for the PCB, and the power is too low to meet the requirements.
