QPS-45-12

AC DC Converters

AC DC converters are devices that convert alternating current (AC) electricity to direct current (DC) electricity. This conversion allows power to be provided to electronic components, such as motors, computers, lights and heating elements. AC DC converters come in various sizes, ranging from small plug-in AC adapters to large industrial units.

The QPS-45-12 is a particular type of AC DC converter, designed specifically for power supply applications. It is a single-phase AC to DC power converter, capable of providing up to 12V at 45A of continuous power. It has a wide input voltage range, low output ripple and low temperature rise, making it suitable for use in a variety of environments. The QPS-45-12 is a reliable and effective solution for industrial power supply applications.

Application Field

The QPS-45-12 converter is suitable for a wide range of applications, including industrial and commercial power supply applications. It is particularly suitable for automation and CNC machine tools, electrical equipment, and lighting equipment. The QPS-45-12 is also well-suited for medical, scientific and military applications.

Working Principle

The QPS-45-12 works by converting AC power into DC power. The AC power is first rectified by a diode bridge. The rectified AC is then filtered by an inductor and a capacitor. The rectified, filtered AC is then fed into an adjustable linear voltage regulator, which produces the DC output. The DC output is then filtered again and fed to the load.

The linear voltage regulator provides the adjustable voltage, allowing the output voltage to be adjusted to the required level. The voltage regulator also ensures a stable output voltage, despite any fluctuations in the input voltage or load current. The QPS-45-12 also provides an alarm output, which can be used to indicate any faults or errors.

To ensure the highest levels of safety and reliability, the QPS-45-12 is designed to the latest industry standards, including UL60950, CE and RoHS. The internal components are of high-quality, with full protection against over-voltage, over-current, and short-circuit conditions. This makes the QPS-45-12 an ideal choice for power supply applications.
