AC DC Converters

The RAC04-09SC series of AC-DC converters, otherwise known as AC-DC switching adapters, use both alternating and direct current to regulate an AC-DC electricity supply. Regulators of this type are often used as power sources for electronic equipment such as audio-visual systems, computers and other devices.

The RAC04-09SC AC-DC power converters work according to the “flyback” circuit, which is a type of power supply in which the conversion of energy from AC to DC is done by using a more efficient combination of transformer, rectifier, and regulator circuits. In the RAC04-09SC converter, alternating current from the mains is first rectified by a diode bridge and then supplied to a control IC and a transformer.

The transformer converts the rectified AC energy into a regulated DC current, at the same time supplying feedback to the control IC, which analyses the current and voltage levels, and makes any necessary corrective adjustments. The transformer primary winding is then excited by a pulse-width modulated waveform to regulate the output voltage.

The transformer primary winding is wound to enable a high level of output power, allowing the converter to be used with high power draw applications. The transformer secondary supplies voltage to the output circuit, where a voltage regulator controls the output voltage to the specified level. The entire operation is controlled by a control IC which simply turns the transformer on and off at the appropriate times to maintain a stable output current and voltage.

The RAC04-09SC series of AC-DC converters is ideal for applications where high efficiency and reliable power supply is required, while keeping the required size and weight as small as possible. It has been used in a variety of applications such as computers, audio-visual equipment, and medical devices. Its efficient transformer and consistent output make it the ideal solution for power conversions in these applications.
