Working Principle

The QPSF-125-24 AC DC converter works by converting alternating current (AC) into direct current (DC) and regulating the output voltage and current levels to provide a precise amount of power. This is done by using a diode-based rectification that converts the AC power to DC power, and then using an inductor coil to regulate the voltage and current.

The inductor coil acts as a transformer, allowing for the precise control of the output voltage and current. The output voltage and current are regulated by controlling the input AC voltage through the use of a pulse-width modulation algorithm. This allows for the precise regulation of the output power, ensuring a steady and predictable output.

The QPSF-125-24 AC DC converter also features overload protection, which helps protect the system from unexpected surges. This is done by using thermistors and a temperature sensitive voltage regulator to protect the components from overheating. Additionally, the system includes a microprocessor-based controller that monitors the output voltage and current, ensuring accuracy and reliability.

Conclusion

QPSF-125-24 AC DC converters are designed to provide precision power control and protect the system from power surges. The system uses a diode-based rectification to convert the AC power to DC power, and then uses an inductor coil to regulate the voltage and current. Additionally, the system features overload protection and a microprocessor-based controller that monitors the output voltage and current.

The QPSF-125-24 is ideal for a variety of applications that require precision power control, such as: high speed/precision DC motor control, power supplies for medical and test equipment, process control, industrial automation, robotics/automation systems, communications switching systems, and residential and commercial lighting.
