DC DC Converters: R0.25D12-3.33.3/P-R Application Field and Working Principle

The DC DC converter R0.25D12-3.33.3/P-R is mostly used in decorative lighting, such as LED lighting, or to interface small standby batteries with control circuits, protection systems and management systems. It is also used in products such as solar electric systems, electric power storage systems, and uninterruptible power supplies.This device is a low-voltage, low-cost, efficient DC DC converter which provides users with reliable conversion of their application power supply from an unregulated input to regulated 5V or 12V outputs.It features an input voltage range of 12-24Vdc, output voltage range of 5V or 12V and a peak efficiency of up to 96%. It is rated to 5A surge for intermittent output power.The R0.25D12-3.33.3/P-R is designed to be a cost effective, reliable solution for transforming an unregulated DC input power supply to a regulated DC output. It can be used in any application that requires power conversion from an unregulated input to regulated 5V or 12V output, such as decorative lighting, battery interface, solar electric systems, power storage systems and uninterruptible power supplies.When it comes to working principle, the R0.25D12-3.33.3/P-R uses a high frequency switching circuit to regulate the input-output voltage and current. Input voltage is fed into a high frequency converter which then regulates the output voltage based on the input voltage. The high frequency switching circuit is designed to cycle on and off at a very high frequency, which creates a pulsating output voltage and current. The output voltage is regulated by adjusting the time spent in each part of the frequency cycle. The switching frequency can also be adjusted to increase or decrease the output voltage.The R0.25D12-3.33.3/P-R also features a constant current build, which helps to maintain a consistent output current. This feature helps to achieve low ripple and a stable output voltage. To further reduce noise, the converter also features several noise suppression technologies, including over-voltage protection, over-current protection and brown-out protection.In summary, the R0.25D12-3.33.3/P-R is a low-cost, efficient DC DC converter that provides reliable power conversion and noise suppression. It can be used in applications such as decorative lighting, battery interface, solar electric systems, electric power storage systems and uninterruptible power supplies. With its high frequency switching circuit, constant current build, and noise suppression technologies, the R0.25D12-3.33.3/P-R ensures high levels of performance with low levels of noise.
