Is the transformer in the monitoring system in the power supply?
Yes, one is a coil transformer made of copper wire and an iron core. We usually call it transformer directly, and the other is the electronic variable switching power supply, referred to as the power supply". The camera gun is generally external 12V power supply (also 24V), most of the project are switching power supply, and the direct use of ~220V camera guns are integrated with a switching power supply, it is also the most integrated circuit switching power supply circuit, a step-down transformer is composed of a line circle after integrated on the circuit board power supply rectifying circuit.
The main functions are voltage conversion, current conversion, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer) and so on. The utility model can be divided into distribution transformers, power transformers, full sealed transformers, combined transformers, dry-type transformers, oil immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc..
Transformer (Transformer) is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and core (magnetic core). In the electrical equipment and wireless circuit, often used for lifting voltage, matching impedance, security isolation, etc..
