1. It must be recognized that the power adapter is a high-frequency, long-term electronic product, such as a mobile phone charger, which is basically used every day.
2. The power adapter is a product that requires safety certification, and there may be a short circuit or burning during use.
In short, users must consider quality issues when purchasing power adapters, and the quality is reliable before they can be used safely. 24V power adapter
The wall-plug certified power adapter switching power supply refers to a power supply that controls the time ratio of switch on and off through modern electronic technology, and the wall-plug certified power adapter maintains a stable output voltage. The switching power supply of the power adapter Generally composed of pulse width modulation (PWM) control IC and MOSFET, advantages: high conversion power, small size, can operate in a wide voltage range
The essence of the communication power adapter is the DC/DC converter type power adapter, but it is generally powered by DC 48V or 24V, and uses a backup battery as a backup for the DC power supply, and converts the DC power supply voltage into the working voltage required by the circuit. Generally, it is It is divided into three types: central power supply, layered power supply and single-board power supply, with the latter having the highest reliability. 24V power adapter
There are generally two types of power adapters: one is a switching power supply, and the other is a transformer-type power supply. The switching power supply circuit is more complex and has many components, so it is a new type of power supply. The latter is a very common power supply with relatively simple components, mainly including step-down transformers, rectifier diodes, filter capacitors, etc. The relatively high-end ones are also composed of voltage regulator protection circuits.
Generally below 36W, plug-in power adapters are mostly used. The feature of this kind of power adapter is that it does not need AC wires, which saves the cost and space, and does not need the countertop space for placing the power supply. It is also safer to plug directly into the plug board. There are a few power adapters below 36W that use desktop type. This is generally because the product used is far away from the AC plug board or because the power adapter is bulky and heavy, or The power adapter is heavy hanging on it.
