DC DC converters are widely used in today's electronic systems to efficiently convert a DC voltage from one level to another with minimal power loss, with REC5-243.3SRWZ/H/B/SMD being one of the most common. While the applications and working principles of such a device vary in form and function, the main elements remain the same.

Applications

REC5-243.3SRWZ/H/B/SMD DC-DC convertors are typically used in communication systems, industrial systems and some satellite systems. It can be used in applications such as power conditioning, multiple output voltage regulation, fault protection, and transducer power supply. Additionally, they also generate power for oscilloscope sweeps and line transmission. The REC5-243.3SRWZ/H/B/SMD is mainly used in applications where multiple power sources of different voltages are required, such as motor and power control cabinets, motor controllers, industrial automation, remote sensor power, and telecommunications.

Working Principle

The working principle of a REC5-243.3SRWZ/H/B/SMD DC-DC converter is simple: it uses an inductor and a set of switches to convert the input voltage to the desired output voltage. First, the switch opens, something that causes the current to flow through the inductor, which causes the stored energy to be increased and thus the “voltage” at the inductor terminals increases. Second, the switch closes, something that causes the current to flow in the opposite direction. Finally, the stored energy is transferred back to the load.

The power control of the REC5-243.3SRWZ/H/B/SMD regulator is done by controlling the switching times and changing the duty cycle. This helps achieve multiple output voltages, depending on the application. The use of the control circuit permits different types of topologies, such as step-down, step-up, buck-boost, and even unidirectional diode-bridge configurations.

Features & Advantages

The REC5-243.3SRWZ/H/B/SMD is a medium power, enclosed, regulated DC-DC converter. It offers high efficiency (up to 95%), low output ripple, low power losses, low audible noise, and wide input voltage range. It also offers an integrated thermal shutdown protection to reduce the load in case of over temperature.

It supports a wide input voltage range from 36V-75V and provides power up to 183W with an output voltage of 5V to 12V. The high switching frequency of 500 kHz helps reduce the size of the internal components, making the product ideal for space-constrained applications. It is also EMC-compliant and offers protection from overvoltage, overcurrent, and short circuit.

Conclusion

The REC5-243.3SRWZ/H/B/SMD converter is an excellent choice for applications where multiple power sources of different voltages are needed. It is a highly efficient DC-DC converter, offering high efficiency, low noise, and wide input voltage range. It is also cost-effective, easy to use, and easy to integrate into existing systems. Additionally, it offers important features such as protection against overvoltage, overcurrent, thermal shutdown, and short circuit.
