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.
