DC-DC converters are in a league of their own when it comes to powering electronics and equipment that require a higher and more focused voltage. They are definitely more complex than AC-DC converters with a higher degree of efficiency. The REC10-2405S/H2/M is a fine example of these kinds of converters and today we are looking at its application field, working principle and more.

The REC10-2405S/H2/M essentially converts an input of 24 - 28V DC at an output of 5V at a maximum current rating of up to 20A. This essentially means that the converter has a maximum power output of 100 Watts. There really isn’t much else to explain when it comes to its power output but its application field is quite big.

The REC10-2405S/H2/M is especially useful for applications that need a higher voltage and current but at the same time at nominal or lower frequencies due to its high efficiency conversion. This is why many top-tier companies opt for the REC10-2405S/H2/M for their applications which includes, but isn’t limited to; emergency lighting, alarm systems, medical machines and backups, industrial control and instrumentation, as well as telecom equipment.

Speaking of efficiency, the REC10-2405S/H2/M is highly efficient due to its advanced synchronous rectification, fixed frequency operation, as well as patented circuitry and design. Its efficiency rating is quite high and can reach up to 93% with a low no-load power consumption of 1W. Additionally, this converter also houses a new advanced MOSFET soft start circuit to reduce inrush currents when it is first powered up.

The REC10-2405S/H2/M is also quite resilient and reliable and you bet that it can manage a high temperature up to up to 90°C. Reliability is key for any industrial application and thankfully, the REC10-2405S/H2/M guarantees you just that. Additionally, this unit supports a very hospitable MTBF rating of up to 1 million hours as well as an impressive range of voltage variations from -25%, -20%, and + 5000 ppm from the rated output voltage.

Now that we know what it offers, it’s time to explore its working principle. The REC10-2405S/H2/M is a fluctuating output converter. It converts a 24V to 28V DC input to a 5V DC output. The conversion is handled by a pair of primary and secondary side controllers employing a synchronous rectification control, allowing converters to work at high efficiency levels.

The primary side controller manages the entire unit operations and employs a hybrid topology to operate at an improved efficiency. It also manages the fault protection circuit and the secondary side synchronous rectification, further improving efficiency and reducing the total power consumption.

The secondary side controller is responsible for controlling secondary side regulation and synchronous rectification as well as primary side power saving. The synchronous rectification circuitry is the primary method for improving efficiency by increasing the electrical energy transferred between the input and output stages.

This is essentially how the REC10-2405S/H2/M DC-DC converter works. It is a reliable and efficient converter that is preferred amongst industrial-grade applications. From backing up medical equipment to powering tools in emergency lighting, the REC10-2405S/H2/M is definitely one of the best out there.
