PCB Current Sense Transformer

Providing with quality and standard customer-made electronic and passive components pcb current sense transformer and solution products, Fullstar Electronics is a leading pcb current sense transformer manufacturer and supplier in China. welcome to wholesale electronics pcb current sense transformer from our factory.

A PCB Current Sense Transformer is an electronic component specifically designed for printed circuit board mounting. Its primary function is to measure AC current with high precision in a non-contact manner. It proportionally converts a larger AC current flowing through a conductor into a smaller current signal, which is easy for subsequent circuits to monitor and control.

In simple terms, its core role is to "monitor" current without consuming almost any power.

✨ Core Advantages and Features

Compared to other current sensing methods (like using a shunt resistor), PCB current transformers offer several distinct advantages:

Extremely Low Insertion Loss: They don't rely on creating a voltage drop to measure current, so they consume negligible power. This makes them ideal for high-efficiency applications, especially those involving large currents.

Inherent Electrical Isolation: There is no direct electrical connection between the primary (power side) and secondary (control/measurement side). This effectively protects sensitive low-voltage control circuits from high-voltage transients, enhancing system safety.

Excellent Accuracy: By carefully selecting the turns ratio and the burden resistor, a high degree of measurement accuracy can be achieved.

Easily Adjustable Signal: The ability to scale the current signal simply by changing the burden resistor offers great design flexibility.

Suitable for High-Frequency Applications: They are particularly adept at measuring high-frequency AC or pulsed currents found in switching power supplies, typically ranging from tens of kHz to over 1 MHz.

Of course, there are some limitations to consider:

Primarily for AC Measurement: Standard models cannot measure pure DC current.

Occupies PCB Space: They are physically larger compared to tiny components like shunt resistors.

Relatively Higher Cost: They are generally more expensive than discrete components like resistors.
