PRODUCT OVERVIEW
The MINMAX MKE20-HI series is a range of high performance 20W DC-DC converter within encapsulated 2"x1" package which specifically design for high
isolation applications where reinforced insulation and high working voltage are required. 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 8000VDC with reinforced insulation, which rated for 1000Vrms working
voltage. Further features include under-voltage, overload, over voltage, short circuit protection, no min. load requirement, EMI emission EN 55032 Class A
approved, low I/O capacitance 80pF max. and operating ambient temp. range by -40
℃ to 80℃ by high efficiency up to 90%. MKE20-
HI series conform to
UL/cUL/IEC/EN 62368-1 (60950-1) safety approvals. The MKE20-HI series offer a superior solution for demanding application in requesting a certified
supplementary.
