20-W dc/dc converters ruggedized to meet EN 50155 and EN 61373

The MKZI20 family of 20-W dc/dc converters come in the industry standard 1 x 2-in. footprint and have been ruggedized to meet EN 50155 and EN 61373 for increased temperature, humidity, shock, vibration, and other parameters in railway on-train applications.

The 20-W MKZI20 family consists of 18 models with ultra-wide input ranges of 9-36/18-75/40-160 Vin and outputs of 5/12/15/24/±12/±15 V in a small 1.00×2.00×0.43-in. shielded and encapsulated package. The MKZI20’s features: Reinforced Isolation rated for 3,000 Vac; high efficiency up to 90%; wide operating Temperature range of -40 to +95° (see curves) assure reliable performance for critical applications; tight regulation; low no-load power consumption; integral EMI filter to meet EN55022 Class A; remote on/off; and Vout Trim (±10%).

Built-in protection circuits include under-voltage lockout, over-voltage, over-temperature, over-current and short circuit protection. The MKZI20 family has been intensely qualified to meet: UL/cUL/EN 62368-1 (60950-1) standards with CB Report; railway certification to EN50155 (IEC60571); Fire Protection to EN45545-2; Shock & Vibration to EN61373; cooling, dry & damp heat testing to IEC/EN60068-2-1,2,30; and railway EMC standard to EN50121-3-2. All models are Conflict-Free/Reach/RoHS/Hazardous Substance Process Management (IECQ QC 080000) compliant and backed by a five-year warranty.

Models are in stock and available for immediate evaluation through MinMax and distributors. Documentation including datasheets, safety reports, compliance statements and 3D models are available from www.minmaxpower.com. Prices are as low as $26.5 in 299 piece quantities.
