Non-isolated DC/DC converter has 98 per cent efficiency
A 3kW buck-boost DC/DC converter produced by Recom in a half-brick baseplate-cooled package has efficiency of 98 per cent.
The Recom RBBA3000 buck-boost, non-isolated, DC/DC converter features a maximum of 3kW of output power rating in an industry-standard half brick baseplate-cooled package.
Input range is 9.0 to 60V DC and the output voltage and maximum current can be user-programmed from 0 to 60V DC and 0 to 50A respectively. Programming can be via a single resistor or by an externally applied voltage.
The buck-boost topology used in the Recom RBBA3000 allows the output voltage to be set lower or higher than the input voltage. With 98 per cent conversion efficiency, the RBBA3000 provides a full power over an operating temperature of -40 to +85 degrees C when appropriately cooled, adds Recom. The load current can be monitored from a current share pin which can also be used to parallel two modules to provide up to 100A output with active load balancing.
The converter complies with EMC standard EN55024 and also EN 55032 class A and B with an external filter. Typical applications are 48 to 24V or 12 to 24V battery power conversion, electric vehicle voltage regulators, battery voltage stabilisers or high power laboratory DC power supplies.
The RBBA3000 is also backed by Recom’s two-year warranty.
Samples and OEM pricing are available from all authorised distributors or directly from Recom.
Recom Power supplies a full range of DC/DC and AC/DC converters in every power class up to 960W alongside switching regulators and LED drivers in a wide selection of designs. Innovations such as the company’s R-78 switching regulators have become industry standard.
The company is headquartered in Gmunden, Austria and includes a logistics centre and laboratory wing. Recom has a worldwide distribution network.
