MENB1020A0512F01

Application Field

The MENB1020A0512F01 is a universal AC/DC converter power supply, with 12V/0.84A output. It is widely used in professional and residential markets, such as CCTV security systems, LCD & LED lightings, household appliances, communications equipment and more. It is also a good choice for those professionals who want to maintain an energy-efficient lifestyle by having superb efficiency up to 91%.

Working Principle

The MENB1020A0512F01 adopts the twostage technology of rectification & PWM (Pulse Width Modulation), which has been widely applied in the AC/DC power adapters. The working principle of two-stage technology is shown in the figure below.

In the first stage, the alternating-current input is rectified and filtered to produce a directcurrent voltage.The filtered direct-current voltage is then sent to the PWM (pulse width modulator) section where it goes through a process of rectification, regulation, and isolation before outputting to the load.

PWM technology allows an input of wide range of input voltage (e.g. 90-265Vac) to be converted into a regulated output voltage, creating a stable output signal. The output of the converter is isolated from the input voltage, minimizing the risk of voltage shocks and electrical accidents occurring.

Conclusion

The MENB1020A0512F01 is a reliable power adapter providing 12V/0.84A output power. It is widely used in professional and residential applications and utilizes the two-stage technology of rectification & PWM to output a stable voltage. With the added benefits of energy efficiency and protection against electrical shocks, this power adapter is an ideal power solution for those who want a safe and energy-efficient lifestyle.
