Recom has launched two series of certified, ultra-high isolation DC-DC converters with single and dual outputs rated at 2W or 3W in a 16pin package

The RHV2 and RHV3 series unregulated DC-DC converters have high isolation ratings of 12.5kVAC/one minute or 20kVDC/one second in a SIP16 package that measures 45 x 15 x 17mm.

The input-to-output pin separation of 30mm assists with certification to IEC/EN 62368 and IEC/EN 61010 for 12.5kVAC reinforced isolation up to 5000m altitude. The RHV2 provides 2W up to 85°C and the RHV3 up to 3W at 80°C without load derating.

Both series of DC-DC converters have nominal 5, 12 or 24V inputs and a choice of 5, 12, 24 single or  +/-5 or +/-12V dual outputs. Efficiency is up to 81.5 per cent, isolation capacitance is 4pF typical and the parts comply with EN 55032 (class B) EMI limits with a simple external LC input filter. Reliability is very high with MTBF at 14.6M hours for the RHV2 series at 25°C (13.4M hours for RHV3).

“We see the RHV2 and RHV3 series as a perfect fit for very high voltage isolation applications such as high vacuum monitoring, X-ray equipment and HVAC dust extraction systems where low cost and reliable performance are key,” said Steve Roberts, CTO of Recom

Samples and OEM pricing are available from all authorized distributors or directly from Recom.
