DC-DC converters are electronic devices that transform varied power sources to a regulated output voltage or use current sourced from an AC switching power supply. DC-DC converters are used in a wide variety of applications, ranging from industrial to Telecommunications and from Computer Systems to Vehicle Electronics.

One of the most popular DC-DC converters is the RSO-4805SZ/H2. This converter serves as a voltage regulator in the 4-20mA current loop. It provides an adjustable output voltage of 0 to 5.06V (with an accuracy of ±1%). It also features a wide input voltage range of 6.5-18V and can supply up to a maximum output current of 1.5A. It is available in three versions – board mount, flexible cable mount and enclosure mount.

Application Field

The RSO-4805SZ/H2 DC-DC converter is widely used in industrial control and automation systems. It is often used for applications such as smart meters, process control, and data acquisition. This device is also used in automotive and telecommunication industries due to its high level of accuracy and reliability. Additionally, it is used to supply regulated voltage in computer systems, as well as being used as part of a switched mode power supply.

Working Principle

The working principle of the RSO-4805SZ/H2 DC-DC converter is based on the operation of a buck converter. A buck converter is an efficient DC-to-DC converter that can connect a higher voltage source to a lower output voltage. In the RSO-4805SZ/H2, an internal control circuit uses a Pulse-Width Modulation (PWM) technique to control the current and voltage output. It monitors the output voltage and adjusts the duty cycle of the PWM signal according to its internal programming in order to maintain a stable output.

The RSO-4805SZ/H2 has a wide input voltage range of 6.5-18V and can supply up to a maximum output current of 1.5A. It has two operating modes, one is a constant voltage mode and the other is a constant current mode. The device’s operating frequency is set at a fixed switching frequency of 300KHz. This device is also protected from short-circuit, over-current, and over-temperature.

Conclusion

The RSO-4805SZ/H2 DC-DC converter is a reliable and efficient converter that is used in a wide variety of applications. Its adjustable output voltage, wide input voltage range, high accuracy, and robust protection features makes it suitable for both industrial and automotive use. It easily monitors and maintains a stable output voltage or current and is an ideal choice for applications requiring precision voltage regulation.
