3, 6 & 15 Watt medical DC/DC converters offer 2 x MOPP and patient leakage to 2 µA
Regulated DC-DC converters for medical applications
The JHL & JHM series of encapsulated, isolated and regulated DC-DC converters for medical applications. Available with single and dual outputs, the 3 Watt JHL03, the 6 Watt JHL06 and the 15 Watt JHM15, 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 40.6 x 25.4 x 10.2 mm for the JHM15 series.
All models are approved to the 3rd edition international medical safety standards EN60601-1:2006 and ANSI/AAMI ES60601-1:2005, feature a low 2 µA maximum patient leakage current, and offer 2 x means of patient protection (2 x MOPP). They also have a double / reinforced isolation barrier that provides 4000 VAC maximum input to output isolation for one minute with a 250 VAC working voltage.
The JHL03 and JHL06 series single output models are available with 5, 12 or 15 VDC and duals ±12 or ±15 VDC. Two input range variants are available across the JHL series, 10–17 or 20–30 VDC, accommodating nominal 12 or 24 VDC applications.
The JHM15 series comprises two 2:1 input voltage range options of 9 – 18 or 18 – 36 VDC. Singles provide 5, 12, or 15 VDC and duals ±5, ±12 or ±15 VDC models.
An output voltage trim function is available across the JHL/JHM series and provides a ±10% adjustment of the output in order to accommodate losses or for special applications.
Meeting industry standards for both conducted and radiated emissions
The units meet the EN55011 Level A EMI standard for both conducted and radiated emissions without the need for any external filtering components.
Capable of operating in most environments and over an extended operating temperature from –40 to +80 degrees, the JHM15 can deliver the full output power up to + 60 degrees C without derating. The JHL03/06 series operate from -20 to + 80 degrees C with full output power available up to +60 degrees C.
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.
