Medical, 2 x MOPP, DC-DC converters simplify development of safety-critical medical devices

April 2, 2019 XP Power

April 2nd, 2019 – XP Power has launched a new range of 20 Watt DC-DC power modules with international agency approvals for medical/healthcare applications. The series is suitable for all medical applications and particularly intended for use where the DC-DC converter provides a reinforced (2 x MOPP) safety isolation barrier, including patient contact and patient vicinity applications.

Modules in the JHM20 series are certified by both UL & TUV and carry all international approvals including IEC60601-1, EN60601-1 and ANSI/AMMI ES60601-1 for medical safety. This certification, and with the CB report including risk management, allow designers to use them for critical safety barriers with confidence, while reducing the time and cost associated with the end equipment approval. Suitable for direct patient contact, the modules have a maximum of just 2.5μA of patient leakage current and offer 2 x Measures of Patient Protection (MOPP) at a 250VAC working voltage, ensuring patient and operator safety.

The JHM20 series comprises a total of 18 modules, offering 20 Watts of power in a compact 2” x 1” PCB-mount footprint. The 2:1 input range offers flexibility with nominal input voltages of 12, 24 and 48VDC. Isolated, fully-floating, single and dual output versions are available at 5, 12 and 15VDC, allowing the provision of single rails of 24 and 30VDC. All single outputs are simple to trim by ±10% via a single external resistor.

The modules offer excellent levels of efficiency and operate from -40°C to +80°C, delivering full power at temperatures up to +60°C allowing use in challenging applications. A wide range of protection mechanisms such as short circuit and overload are included to protect both the power module and the system load. The case is made from a self-extinguishing UL94V-0 material.

JHM20 modules are certified to meet the EN55011 Level A standard for EMC emissions without the need for any external components. It is also certified to IEC60601-1-2 Ed. 4 for EMC immunity. These pre-certifications ease the task of the designer when submitting for system-level approvals.

Further Product Details:

The JHM20 series is priced at $42.17 for 500 pcs orders and is available from Allied Electronics, Digi-Key, Newark or direct from XP Power and comes with a 3-year warranty.
