The P33-150ST AC DC converter is a switching power converter designed for a variety of applications, such as heavy industry, communications, medical equipment, and computers. It is a microprocessor-controlled, high-efficiency converter using pulse width modulation (PWM) technology. It has a wide input voltage range of 90-264VAC and provides a stable output voltage of 12V. Its rated output power is up to 150W. With a 4-string multi-level topology, the output waveform is very close to a pure sine wave, and its total harmonic distortion (THD) is less than 5%. It is designed with an active clamp circuit, providing a soft-start and current limiting. It provides comprehensive protection features against overvoltage, overtemperature, short circuit, and over-current events.

The P33-150ST makes use of an input rectifier circuit and output filter together with a long-term high-frequency switching circuit. The input rectifier circuit, consisting of a diode bridge and an EMI filter, provides the rectified high-frequency DC voltage. The output filter, composed of an inductor, a capacitor, and a resistor, is used to reduce the high-frequency ripple and provide a smooth DC output voltage. The high-frequency switching circuit is used to modulate the output voltage by switching the input current on and off with precise timing in order to control the output voltage and power. The microcontroller provides the switching signal for the high-frequency switching circuit. It is also responsible for monitoring the input and output voltages to detect any abnormalities.

The P33-150ST AC DC converter is an ideal choice for powering high-performance electronic equipment, such as telecom base stations, industrial control systems, and medical imaging equipment. Its high efficiency, high power density, and low noise design make it suitable for a wide variety of applications. With its comprehensive protection features and high reliability, the P33-150ST is an ideal solution for powering mission-critical systems.
