AC/DC power supply NT255

DIN rail

Power supply of modules via backplane Supply voltage: 18 to 34 V DC Monitoring of supply voltage Power-fail signal for processor module Galvanic isolation Output power: 45 W (55 W) Buffer time: 18 ms With the NT255 Bachmann electronic sets new standards for the power supplies of CPUs and backplane-supplied modules. As a result of intensive development work and in consideration of field experiences with several thousand supply modules, the NT255 combines long term know-ledge with the latest technologies. Best possible, selected components and lifetime optimized design form the reliable base for the module. Recent planar transformer technologies ensure a significantly increased efficiency, the integrated heat dissipation in the circuit board (»coolPCB technology«) prevents even minimal local warming and thus the early ageing of components. Moreover, because of the extremely reduced weight of the parts, the module is even more robust against shock and vibrations. In spite of the primary design focus on a long service life and robust design, the NT255 also offers outstanding technical features: up to 80 % longer buffer time at short voltage drops and generous power reserves (55 W peak power) for temporary overload ensure safety and reliability in every respect.
