FUNCTIONAL DEVICES INC / RIB TR40VA004 Class 2 Transformer 24vac 40 Va 1 Ph

Functional Devices Inc / Rib TR40VA004 Class 2 transformer is employed to provide a safe & reliable power source for transforming higher voltages to lower voltages in air conditioning (HVAC) systems. This transformer is suitable for industrial and building automation settings.

Working Mechanism:

• Operating based on the principle of electromagnetic induction, this current transformer functions by utilising alternating current (AC) in the primary conductor, generating a surrounding magnetic field.
• Following Faraday's law of electromagnetic induction, the magnetic field induces a voltage in the secondary winding.
• External circuitry is employed to convert the induced voltage into a proportional secondary current.
• The derived secondary current is utilised for precise measurement and monitoring purposes, commonly applied in devices, such as power meters and protection systems.

Features:

• Functional Devices Inc / Rib TR40VA004 Class 2 transformer features versatile input voltage options, accommodating 120, 208, 240 and 277VAC, ensuring compatibility with a range of electrical systems.
• This Class 2 transformer comes with a 40VA output rating, providing ample power for digital controllers, gas controls, ignition systems and various HVAC control applications.
• It is equipped with inherently limited protection for enhancing safety by restricting current levels and preventing overloads in the transformer.
• This transformer comes with an open enclosure style, facilitating visibility and accessibility for installations on digital controllers, motor actuators and staging controls.
• It features dual 1/2-inch hubs and a foot mounting option, offering installation flexibility.
• This Class 2 transformer includes pigtails for primary connections and 8-inch leads for secondary connections.
• It complies with UL5085-2 or UL5085-3 standards, assuring quality and reliability.

Frequently Asked Questions:

Q. What is the difference between a control transformer and a power transformer?

A. A control transformer is designed for low-power control circuits, offering isolated low-voltage outputs to drive relays and control devices. In contrast, a power transformer is engineered to handle higher power levels for distributing electrical energy across transmission and distribution networks. The focus of a control transformer is precision and safety for control circuits, while a power transformer deals with efficient energy transmission at larger scales.

Q. How to install these transformers?

A.

• The transformer should be installed in a dry, well-ventilated area away from sources of heat and moisture. The area should also have adequate space for maintenance and servicing.
• The transformer should be securely mounted on a flat surface using bolts or brackets that are appropriate for the transformer's weight and size. The mounting surface should be free from any debris and should be able to support the weight of the transformer.
• Before connecting the wiring, ensure the power supply to the transformer is switched off. Connect the primary and secondary wiring according to the wiring diagram provided with the transformer. The wiring should be done by a qualified electrician who has the necessary knowledge and experience to handle electrical installations safely.
• After the wiring is complete, the transformer should be tested to ensure it is functioning correctly. This can be done using a multimeter or a voltage tester. If any issues are detected, they should be addressed before the transformer is put into service.
• Once the transformer has been tested and found to be functioning correctly, it can be put into service. Ensure that the transformer is properly labelled with its voltage and power ratings and that all necessary safety precautions are taken when operating the equipment.
