Switched-mode power supplies SN3 –
The ideal power supplier for your 24 V DC PLCs
The switched-mode power supply unit is indispensable in the
fields of power engineering and automation. The technology features a high efficiency and the development
of heat and power losses are thus kept to a minimum.
The wide input voltage range
which accepts both AC and DC power supplies guarantees world-wide use,
even with fluctuating power networks and battery operated systems.
The new devices feature integrated
performance reserves of up to 50 %; which avoid the necessity for over-dimensioning
with high starting loads. They are also no-load and overload protected
and feature permanent short-circuit proofing.
Devices with adjustable output voltage, e.g. for compensation of voltage drops
on long cable lengths enable matching to the demands of different applications.
An additional annunciation module which can be retrofitted with a remote function
for external switch on and off, as well as a relay output for indicating that the input/output is ok, optimise the monitoring features of the control.
