The typical application fields are communication systems, security systems, computer systems and etc. RP75H-4848SRW/N has the features of high efficiency, high power density, real-time output voltage monitor, and wide input-output mode, which can meet the application requirements in various fields.

Working Principle of RP75H-4848SRW/N:

RP75H-4848SRW/N is a kind of isolated power module with two power transformers, which can convert the input voltage to the output voltage or output current of specific value. The working principle is as follows: the input voltage goes through the transformer T1, and it is converted into a high voltage and transferred to the rectifier bridge after the isolation, then after the rectifier bridge the DC voltage comes out; the DC voltage is transferred to the filter capacitor for smoothing. Then the DC voltage is input to the PWM controller and the secondary PWM controller. The PWM control signal is generated to drive the switching transistor, which drives the coil to promote the transformation efficiency. The output signal voltage is output to the load after the transformation of the transformer T2. In this case, the output signal voltage is close to the output voltage set by the user. In addition, the PWM controller also works with the feedback circuit to regulate the output voltage of RP75H-4848SRW/N.
