Working Principle

The CRNA25-1200 is a single-phase diode rectifier that performs the basic function of changing alternating current (AC) into direct current (DC). In its simplest form, the device consists of two diodes connected in opposite directions, with a load connected in between. When an AC waveform is applied across the device, the diodes alternate between conducting and blocking, allowing current to flow in only one direction. This allows the waveform to be converted into a rectified DC waveform, which can then be used to power DC loads.
