2W and 3W DC-DC Converters have 20kVdc IsolationDecember 16, 2019 by Paul Shepard
RECOM has launched its RHV2 and RHV3 series of certified, ultra-high isolation dc-dc converters with single and dual outputs rated at 2W or 3W in a compact SIP16 package. The RHV2 and RHV3 series feature ultra-high isolation ratings of 12.5kVac/one minute or 20kVdc/one second in a SIP16 package, that measures just 45mm x 15mm x 17mm.
With more than 30mm input-to-output pin separation, the converters are certified 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 have nominal 5-, 12- or 24-V inputs and a choice of 5-, 12-, 24- single or +/-5V or +/-12V dual outputs.
Efficiency is up to 81.5%, isolation capacitance is very low at 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).
Steve Roberts, CTO of RECOM, comments "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"
