Working Principle of REC8-1212SRW/H2/A/M

The REC8-1212SRW/H2/A/M uses a flyback topology to convert the input voltage to the desired output voltage. The switch contained inside the converter is driven by a single-ended pulse width modulation (PWM) based dimming circuit, which adjusts the duty cycle to achieve the desired output. The conversion process works as follows:The input DC voltage is connected to the primary coil of the Flyback transformer and to the primary side rectifier, which rectifies the input voltage and stores it in the output capacitor. The PWM controller generates square wave pulses which switch the transistor on and off. The energy stored in the primary coil is then transferred to the secondary winding. The rectifier diode in the secondary winding rectifies the induced pulses to provide the steady output voltage.The REC8-1212SRW/H2/A/M also features power factor correction (PFC). The PFC stage reduces the harmonic output and helps to maintain the maximum efficiency of the converter. The PFC stage also helps to reduce the output ripple, enabling the converter to deliver a low ripple output even when the input AC voltage is fluctuating.

The REC8-1212SRW/H2/A/M has a number of functions for safety and over-temperature protection. For example, the converter can reduce its internal power consumption if the temperature rises above the pre-set threshold. This helps to protect the converter from thermal damage. Moreover, the converter has the ability to restart after an interruption in input AC voltage. This ensures a high level of reliability.

In conclusion, the REC8-1212SRW/H2/A/M is a highly efficient, cost-effective solution that can be used in a wide range of applications. It has a wide input voltage range, adjustable output voltage, power factor correction and many more features. It’s capable of providing a reliable, constant DC output and is the perfect solution for any application requiring a flexible, affordable DC-DC converter.
