DC-DC converters ideal fit for very high voltage isolation applications

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 series feature ultra-high isolation ratings of 12.5kVAC/one minute or 20kVDC/one second in a compact SIP16 package, measuring only 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 produces 2W up to 85C and the RHV3 up to 3W at 80C without load derating. Both series possess nominal 5, 12 or 24V inputs and a choice of 5, 12, 24 single or +/-5 or +/-12V dual outputs. Efficiency rises to 81.5%, and 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 extremely high with MTBF at 14.6M hours for the RHV2 series at 25C (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.”
