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
• Provides all the necessary CPU voltages as well as supply for
modules on backplanes
• 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)
