The MINMAX MKW20M series is a range of high performance 20W medical approved DC-DC converter within encapsulated 2”x1” package which specifically design for medical applications. There are 21 models available for input voltage of 12, 24, 48VDC with wide 2:1 input range and fixed output voltage. The I/O isolation is specified for 4200VAC with reinforced insulation, which rated for 300Vrms working voltage. Further features include under-voltage, overload, over voltage, short circuit protection, no min. load requirement, EMI emission EN 55011 class A approved, low I/O leakage current 5μA max. and operating ambient temp. range by -40℃ to 80℃ by high efficiency up to 90%. MKW20M series conform to 4th edition medical EMC standard, medical safety with 2xMOPP (Means Of Patient Protection) per 3rd edition of IEC/EN 60601-1 & ANSI/AAMI ES60601-1 approved. The MKW20M series offer a perfect solution for demanding applications in medical instrument requesting a certified supplementary and reinforced insulation system to comply with latest medical safety approval for 2xMOPP requirement.
