UL-60950-1 safety certified 10/15 Watts DC/DC converters from Recom

RECOM has recently introduced REC8, REC10 and REC15 DC/DC converters are now UL-60950-1 safety certified to complement the EN60950-1 certification that they already possessed. This means that they are now approved for applications world-wide.

The REC8 and REC10 are low cost, high performance, regulated DIP24 converters available with 2:1 and 4:1 input voltage ranges and with single or dual outputs. The isolation grade is 2kVDC as standard, with 3kVDC offered as an option. The 10W converter operates industrial ambient operating temperature range (free convection) of -40°C to +85°C without derating, while the 12W converter can work up to maximum operating temperature of +75°C. The converters have efficiencies of up to 87% which remain consistent over the full input voltage range. At 30% load, the conversion efficiency are above 80%. These DC/DC converter modules offer an MTBF of up to 1.2 million hours.

The REC15 is a low cost, high performance, regulated 2"x1" converter also available with 2:1 or 4:1 input voltage range and single or dual outputs. The isolation grade is 2kVDC as standard, with 3kVDC offered as an option. Due to its high efficiency, the 2:1 input 15W converter has an ambient operating temperature range (free convection) of -40°C to +71°C without derating. The converter features synchronous rectification for the higher current outputs and the standard output voltages have been slightly increased to 3.4V and 5.1V respectively to compensate for any voltage drops in the user's application.

All of the REC8 to REC15 converters feature power limiting on the outputs, so hiccupping does not occur if an overload condition exists. The converters also feature very tight output voltage regulation, low output ripple/noise and have a remote enable pin fitted as standard, a useful feature for sequential power-up and shut-down.
