Features

Functional Devices Class 2 transformers feature split-bobbin construction for superior isolation and low capacitive coupling.
They have foot and single / dual-threaded hubs for easy mounting.
These transformers operate at temperatures ranging from -30 to 140 degrees F.
Some Functional Devices RIB transformers are equipped with circuit breakers for overload protection.

Working Mechanism

Functional Devices Class 2 transformer operates on the fundamental principles of electromagnetic induction.
When alternating current (AC) flows through the primary winding of the transformer, it creates a magnetic field around it.
This magnetic field then induces a voltage in the secondary winding of the transformer, which is connected to the load or electronic device.
The transformer supplies a limited amount of power to the connected device.
This restriction prevents excessive voltage that could pose a risk of electrical shock.
