The power conversion specialist, Ideal Power, has announced the availability of the 43MPM20 series of DC/DC converters from P-Duke. The 43MPM20 modules are 20W ultra low-profile Type CF DC/DC converters, certified to the two times MOPPs (Means Of Patient Protection) standard, making them the obvious choice for applications designed for direct patient contact. 

Ideal Power offers 35 different modules in the 43MPM20 series. These provide a range of different specifications, with wide 2:1 or 4:1 input ranges from nine to 75VDC, and output voltage options of five, 12, 15 and 24VDC whilst offering single or dual output modules. The series also features efficiency ratings of up to 90% in a compact 40.6x25.4x35.55mm package.

Typical leakage current for the converters is low at only two microampere, in addition to offering 5000VAC reinforced insulation. Featuring an internal filter meeting EN 55032 Class A standard, as well as an operating temperature range of -40 to +105°C (with derating), together with an operating altitude of up to 5,000m, the series truly has a lot to offer. In addition the modules are designed with over-voltage, current, thermal, under-voltage and short circuit protection.

Jon Vallis, Sales and Marketing Manager at Ideal Power, said: “P-Duke’s design strengths are size, efficiency and operating temperatures, and they use the most reliable components. Being able to offer these new converters is another example of Ideal Power’s strong relationships with world-leading suppliers, and our commitment to ensuring all products meet applicable standards and approvals.”

Devices used in medical applications, in an area where patients might be present, require at least one Means Of Patient Protection (MOPP). In more demanding environments, the higher level of two times MOPPs is required. The IEC/EN 60601-1 standard determines the requirements for electrical safety in medical devices, and in particular, how to protect against electric shock.
