Industrial-Grade Performance With Cost Effective DC-DC Converters


The converters achieve high efficiencies and protect the output against any sudden change in the input voltage

Developed for various industrial, transport and test and measurement applications that require onboard isolated 5V power supplies from a wide 4:1 input voltage range, the RSOE-Z (1 watt) and RSE-Z (2 watts) DC-DC converters offer complete industrial-grade performance.

The 4:1 input voltages of nominal 12V (4.5-18V) or 24V (9-36V) means that 5V, 12V, 24V or 28V regulated or unregulated battery-powered supplies can be used. Under convection cooling, full output power is available with an ambient temperature from -40 degrees Celsius up to +75 degrees Celsius and up to +85 degrees Celsius with power derating.

The converters achieve efficiencies of up to 80 per cent at full load and over 65 per cent efficiency at 15 per cent load. The tight output regulation (±0.5%) protects the output against any sudden change in the input voltage, and they are overload and continuous short circuit protected. Class A EMC levels can be reached with a simple line inductor filter while class B compliance can be met with a cost-saving common-mode input filter.

The converters come in a compact SIP8 industrial standard package (21.8 x 9.2 x 11.1 mm) and have 2kVDC isolation and a CTRL pin. They are both fully certified according to UL/IEC60950 and UL/IEC/EN 62368-1. Samples and OEM pricing are available from all authorised distributors or directly from RECOM.
