JHL & JHM Series DC-DC Converters (JHL03, JHL06, & JHM15)

April 22, 2016

JHL & JHM series of encapsulated, isolated, and regulated DC/DC converters for medical applications feature a low 2uA maximum patient leakage current and offer 2x means of patient protection (2 x MOPP). They also have a double/reinforced isolation barrier that provides 4,000V AC maximum input to output isolation for one minute with a 250V AC working voltage.


The units meet the EN55011 Level A EMI standard for both conducted and radiated emissions without the need for any external filtering components. JHL03 and JHL06 series single output models are available with 5, 12 or 15V DC and duals +/-12 or +/-15V DC. JHM15 series comprises two 2:1 input voltage range options of 9 to 18 or 18 to 36V DC.
