With the NT255 Bachmann electronic sets newstandards for the power supplies of CPUS andbackplane-supplied modules. As a result of intensivedevelopment work and in consideration of feldexperiences with several thousand supply modulesthe NT255 combines long term knowledge with the latest technologies.

Best possible, selected components and lifetimeoptimized design form the reliable base for themodule. Recent planar transformer technologiesensure a signifcantly increased efficiency, theintegrated heat dissipation in the circuit board(-cooipcb technology)prevents even minimal localwarming and thus the early ageing of componentsMoreover, because of the extremely reduced weightof the parts, the module is even more robust againstshock and vibrations

In spite of the primary design focus on a longservice life and robust design, the NT255 also offersoutstanding technical features: up to 80 %o longerbuffer time at short voltage drops and generouspower reserves (55 W peak power) for temporaryoverload ensure safety and reliability in everyrespect.

• Input voltage range 18 to 34 VDC

• 45 W output power (55 W peak power)

• Galvanic isolation input /ground • Galvanic isolation input / system

• Electronic reverse polarity protection

• 2 state indicators allow differentiation between supply failures and internal errors

• Monitored supply voltage

• Monitored output voltages

• Power-fail signal and state information for CPU module (processable from application)
