Medical DC/DC converters feature 2uA maximum patient leakage

Designed and certified for medical applications, XP Power has announced the JHL and JHM series of encapsulated, isolated and regulated DC/DC converters. The 3W JHL03, 6W JHL06 and 15W JHM15 are approved to the 3rd edition international medical safety standards EN60601-1:2006 and ANSI/AAMI ES60601-1:2005, feature a low 2uA maximum patient leakage current and offer 2 x MOPP.

Available with single and dual outputs, the DC/DC converters are all packaged in industry-standard format cases. Their size is model dependant, ranging from an industry standard DIP-24 for the JHL03 and JHL06 through to 40.6x25.4x10.2mm for the JHM15 series. They also have a double/reinforced isolation barrier that provides 4,000VAC maximum input to output isolation for one minute with a 250VAC working voltage.

An output voltage trim function is available across the single output models of JHL/JHM series, and provides a ±10% adjustment of the output in order to accommodate losses or for special applications. The units meet the EN55011 Level A EMI standard for both conducted and radiated emissions without the need for any external filtering components.

Typical applications include medical devices that require a low power isolated and regulated DC/DC converter that has an extremely low patient leakage current and reinforced insulation.

The JHL03 and JHL06 series single output models are available with 5, 12 or 15VDC and duals ±12 or ±15VDC. Two input range variants are available across the JHL series, 10-17 or 20-30VDC, accommodating nominal 12 or 24VDC applications. The JHL03/06 series operate from -20 to +80°C with full output power available up to +50°C.

The JHM15 series comprises two 2:1 input voltage range options of 9-18 or 18-36 VDC. Singles provide 5, 12, or 15VDC and duals ± 5, ±12 or ±15VDC models Capable of operating in most environments and over an extended operating temperature from –40 to +80°C, the JHM15 can deliver the full output power up to +60°C without derating.
