AC DC Converters: QPS-20-15Application Field and Working PrincipleAC/DC converters, also known as AC/DC adapters, are devices used to convert and supply alternating current (AC)to direct current (DC). This process is typically required when a device uses an ACpowered power source, but requires DC power from the power supply unit. QPS-20-15 is an AC/DC converter known for its reliable, long-lasting performance in demanding applications.QPS-20-15’s application field is primarily in industrial, medical and military equipment. The device is designed to provide a peak power of up to 15 amps (20 watts) and a continuous current of up to 8.25 amps (13.8 watts). The converter is able to efficiently convert AC to DC power, making it a cost-effective solution for many applications. Additionally, the device is UL certified, meeting the highest safety standards.The circuitry of QPS-20-15 is well-designed to ensure efficient operation. Its working principle is based on the principles of rectification, regulating, filtering, and linearization. Rectification is the first step in converting AC to DC. In this step, the AC current is converted to a unidirectional current, pulses of DC current. These pulses are then regulated through an adjustable voltage regulator, which ensures that the output voltage remains constant regardless of varying input voltage values. The filtered DC output is then linearized to produce a quiet, smooth and stable DC output voltage. The AC/DC converter is also designed to be reliable and safe. The device features built-in over temperature and short circuit protection for improved reliability. The device also includes over voltage protection (OVP) and under voltage protection (UVP) to ensure uninterrupted operation and protect the load from potential damages caused by power spikes. The device is extremely versatile and capable of operating at temperatures ranging from -20 °C to +81 °C and humidity levels between 5% and 95%. The device also features an isolation rating of at least 3kVac, making it an effective solution for industry requirements.QPS-20-15 has proven to be an efficient, reliable, and cost-effective AC/DC converter for a variety of applications. It is able to convert AC voltage to highly stable DC voltage, ensuring that the electronic device in operation receives a constantly regulated DC voltage. This AC to DC converter is versatile and reliable with a well-designed circuitry which ensures safe, long-lasting operation.
