The MINMAX MKZI40 series is a latest generation of 40 Watt railway certified and isolated DC-DC power modules with ultra-wide input range of 36-160Vin
for railway DC system and 7 models available for 5/12/15/24/54/±12/±15VDC tightly output voltage within compact size 2”x1” size with shielded and
encapsulated package which specifically design for railway/railroad, battery-powered and harsh environmental applications. Key performance featuring
high I/O isolation 3000VAC with reinforced insulation, high efficiency up to 90%, operating ambient temp. range -40℃ to +77.5℃, no min. load
requirement, very low no-load power consumption, remote on/off, output voltage trim, build-in fault condition protection include under-voltage, overload,
over-voltage, over-temperature and short circuit protection.
The MKZI40 series complies with railway certification EN 50155 (IEC 60571) which conform to vibration and shock/bump test EN 61373 approved,
cooling/dry/damp heat test IEC/EN 60068-2-1,2,30 approved, railway EMC standard EN 50121-3-2 approved and fire protection test EN 45545-2 approved.
The MKZI40 series has been intensely qualified to safety approval UL/cUL/IEC/EN 62368-1 with CB report and CE marking which offer a solution for the
applications where wide input voltage range, high efficiency for wide operating ambient temp. range, isolated power with high I/O isolation & insulation
level, robust environmental & mechanical sustainability and even railway certification are required.
