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.

Standards and Approvals

  • CE
  • RoHS
  • UL

Frequently Asked Questions

What distinguishes Class 2 transformers in terms of safety?
