AC DC desktop, wall adapters are essential components for most electronic devices as they make it possible to convert AC electricity to DC so that the device is powered up. The SDI18-24-UD2-P6R application field and working principle is no exception.

The SDI18-24-UD2-P6R is a single output ac-dc desktop adapter with a voltage range of 18-24V. Its wattage is up to 46W and has 92% power efficiency. Its input voltage is 100-240V AC and 50/60Hz, and the power cord can be bought separately. It dons the outer casing of a UL94V-0 plastic, making it a really reliable product.

The working principle of the SDI18-24-UD2-P6R is relatively simple. Its powers up the connected devices by converting AC electricity to DC electricity using rectifying and smoothing circuits. The rectifying circuit is a bridge type rectifier using four diodes, DI1, DI2, DI3, and DI4. After they rectify the AC to DC, the output goes through a filter condenser to smooth out the voltage waveform, similar to a filter capacitor\'s function in the audio system.

Once the device is powered, there are automatic state-control protections that would be enabled. These include the overvoltage control, overcurrent control, and short-circuit protection. The circuit is able to detect when the output is abnormal and trigger the protection immediately. On top of that, the adapter would also have temperature control to ensure that the device operates well in the normal temperature range.

The performance of the SDI18-24-UD2-P6R has also been tested and proved to meet the international standards. It has achieved the certification of the UL safety standard and the resulting electromagnetic interference (EMI) is also limited. The various safety measures also ensure that the adapter would be resistant to various dust, moisture, and vibration. These tests serve to confirm the reliability and the commercial level quality of the product.

In conclusion, the SDI18-24-UD2-P6R is a reliable AC DC desktop, wall adapter with a voltage range of 18-24V, wattage of up to 46W, and power efficiency of 92%. Its working principle is relatively simple, and its performance is tested and certified to meet the international standards. With its small form factor, it is a great solution for powering most electronic devices of its kind.
