DC DC ConvertersDC-DC converters are devices that utilize electrical circuits to convert an input DC voltage to a different output DC voltage. These include multiple types of converters such as isolated DC-DC, synchronous rectified DC-DC, non-isolated DC-DC, and more.A REC3-1205SRW/H/B is a type of isolated DC-DC converter designed for single output and high output voltage applications. It offers various advantages including low standby power consumption, high conversion efficiency, low voltage ripple, and extended operating temperature range.The REC3-1205SRW/H/B is typically used for high power instrumentation, industrial control systems, avionics, and automotive applications. It offers a wide input range of 7 to 36V and an output range of 5 to 12V. The REC3-1205SRW/H/B also has a wide temperature range from–40°C to +85°C with an operating temperature range up to +105°C. The working principle of the REC3-1205SRW/H/B follows a typical isolated DC-DC converter design. It utilizes a transformer to isolate the input side from the output side, and components such as diodes and FETs to rectify the AC voltage generated by the transformer to a DC voltage. The transformer turns ratio (number of turns on primary winding to secondary winding) is also optimized to achieve the desired input and output voltages.The transformer’s primary winding is connected to the input voltage and the secondary winding is connected to the FETs and diodes. The output voltage is then taken from the diode output. This is done by connecting two diodes in anti-parallel configuration in order to form a bridge rectifier circuit. The voltage at the output is the same as the input voltage, but is stepped down according to the turns ratio of the transformer. The REC3-1205SRW/H/B also utilizes a switching regulator to allow for efficient voltage conversion and protection against overvoltage and overload. The switching regulator keeps the output voltage constant thus making it ideal for applications where precise voltage regulation is required.The output voltage of the REC3-1205SRW/H/B is also adjustable. This makes it suitable for high power applications where the output voltage needs to be adjusted for changing requirements. It can also be programmed to provide different voltage levels by varying the duty cycle of the PWM signal to the switching regulator. In summary, the REC3-1205SRW/H/B is a high power isolated DC-DC converter suitable for high output voltage applications. It utilizes a transformer to step down the input voltage to the desired output voltage, and a switching regulator to maintain the output voltage. The output voltage can also be adjusted for different requirements. It offers low standby power consumption, high conversion efficiency, low voltage ripple, and an extended operating temperature range. The REC3-1205SRW/H/B is typically used for high power instrumentation, industrial control systems, avionics, and automotive applications.
