The basic component of power supply

Shenzhen XED Power Supply Co., Ltd is a professional manufacturer of power supplies for more than 10 years, with high quality and strong R&D team., and the Power supply could be applied in Monitoring, CCTV camera, outdoor waterproof power supply, and Electronics industry(such as router power supply, monitor power supply, laptop power supply, vehicle recorder, etc.)

Basic accessory parts for a power supply：

1>The switching transformer——- is one of the central parts of a power supply.

2>VDR(voltage-dependent resistor)—protecting the circuit from damage.

3>Inductive Coil— reducing the magnetic disturbing.

4>Rectifier bridge(D3SB)- –transferring the voltage 220V to DC.

5>Filter Capacitor(180μF/400V)—reducing the DC ripple with a more reliable circuit.

6>IC–the most important part to maintain circuit and voltage adjustment.

7>Fuse-protecting other electronic components for over-current/voltage.

8>Switch tube–it is one of the central parts of the switching power supply.

9>Secondary filter capacitor-820μF/ 25V

One Switching power supply contains the above components, and there are some other capacitors &components on the PCB board.

10>Secondary rectifier tube-transferring the related voltage to low voltage DC.

11> Temperature probe-detecting the internal temperature of the power supply, and protecting the power supply from being damaged.

Above is the basic component and details information for a power supply. If you have any good suggestions or any requirements, just contact XED at any time. We will do our best to help you.
