AC/DC Desktop Adapters: DPS120125-P7/RN Application Field and Working Principle

AC/DC desktop adapters are external power supplies designed for household and commercial use. They are classed as non-isolated DC/DC converters and provide a stable, low-voltage output to a variety of electrical appliances. The DPS120125-P7/RN is a high-efficiency AC/DC desktop adapter that provides reliable direct-current power for a variety of applications.The DPS120125-P7/RN AC/DC desktop adapter is a Class I power supply designed specifically for medical applications, including ECGs, ventilators, anesthesia delivery systems and blood pressure monitors. It is rated at 12 volts and provides an output current of 1.25 amps at full load. The unit features an input voltage range of 90 VAC to 264 VAC, making it suitable for use in many global markets. The adapter is protected by built-in short-circuit, overload and over-voltage features to ensure safe operation.

Working Principle

The DPS120125-P7/RN AC/DC desktop adapter operates on the principle of voltage transformation. It uses a transformer to convert the incoming alternating current (AC) power from the mains to direct current (DC) voltage. The transformer steps down the input voltage to the desired level and the internal rectifier then converts the AC voltage to DC power.The adapter then passes the output voltage through an inductor, which smoothes out any high frequency noise and spikes in the signal, before it is sent to the load. A filter is also used to remove any incidental high frequency noise. The adapter is regulated using a control loop to ensure a consistent output at all times, regardless of the load or input voltage.

Conclusion

The DPS120125-P7/RN AC/DC desktop adapter is a high-efficiency power supply suitable for medical applications. It operates on a voltage transformation principle, converting incoming AC voltage into regulated DC power in an efficient manner. The adapter features built-in safety features to ensure reliable operation, and its wide input voltage range makes it suitable for use in a variety of markets.
