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?
The distinctive feature of Class 2 transformers is their ability to provide a secure power source by ensuring that the output voltage remains within a predefined and safe range, thereby preventing electrical shock and safeguarding sensitive equipment.
How do Class 2 transformers contribute to operational efficiency?
Class 2 transformers contribute to operational efficiency by adapting to the specific power requirements of connected devices, minimising energy consumption and reducing wastage.
How do I choose the right Fundamental Devices RIB transformer for my specific application?
Choosing the right transformer involves considering factors, such as the power requirements of your devices, the voltage specifications of the transformer and any specific features needed for your application.
