The high efficiency of the device makes it ideal for applications that demand maximum energy savings.

Working Principle

The QSC15048S12 DC-DC converter employs a switching power supply to provide a clean and regulated voltage output. It consists of a switching transistor that is used to convert the 12V battery to 48V AC/DC. The transistor alternately switches between conducting and non-conducting states, resulting in a pulsed voltage from the transistor output that is then rectified to create the desired voltage waveform. The device then converts the AC/DC voltage to 48V DC output. The voltage is then filtered and regulated to ensure that the output meets the required specifications.
