DC/DC converters are important components in a variety of electronic systems. The REC3-1209SRW/H4/A is a DC/DC converter module manufactured by RECOM Electronics. It can provide regulated output voltages between 5V and 12V DC, making it well-suited for applications in which a wide range of output voltage is needed. This paper will discuss the application field and working principle of the REC3-1209SRW/H4/A.

The REC3-1209SRW/H4/A is ideal for applications which require a regulated output voltage between 5V and 12V DC. It can be used in power supply designs, such as systems that required an adjustable output voltage coupled with a regulated output current. The module can also be used to stabilise the output voltage in battery-powered applications such as laptop computers and medical equipment which require a steady voltage supply.

In terms of its working principle, the REC3-1209SRW/H4/A utilises an interleaved discontinuous forward converter with synchronous rectification and a power factor correction circuit. This design uses two primary switching elements, each operating to 4kHz, in order to produce a regulated and nearly smooth output voltage. The input voltage range of this module is from 5.5V to 40V DC, and it can be adjusted by the delta interface to increase the output voltage from 5V to 12V DC. The maximum load current of the module is 6A with approximately 23% DC regulation.

The REC3-1209SRW/H4/A also includes built-in overload protection, over voltage protection and short circuit protection, making it safe to use in electronic systems. The module is compact in size and is also easy to install. It offers a high power density with high efficiency, making it well-suited for applications which require high power yet require a small form factor.

In conclusion, the REC3-1209SRW/H4/A is a high-quality DC/DC converter module which is well suited for applications requiring adjustable output voltage. It features a synchronous rectification design with power factor correction, high power density and a built-in safety protection system, making it an ideal choice for systems which require a reliable and safe power supply.
