The AC2000 N1 / DC2000 N1 / AC3000 N1 / DC3000 N1 switched-
mode power supplies (SNT) provide a highly reliable DC voltage at the
output, which is suitable for direct or battery-buffered supply of critical
loads.
Thanks to the fanless design, a high level of reliability is achieved with
low maintenance requirements. Despite the absence of fans, the SNTs
are very compact with 19" 4 height units (HE) and up to 3.2 kW output
power, thanks to the use of state-of-the-art silicon carbide MOSFETs.
The analog circuit technology - i.e. the absence of freely programmable
components and digital interfaces to the outside - contributes to a
further increase in reliability and availability. This device therefore also
scores highly in terms of future cybersecurity challenges.
Several devices can be connected in parallel to increase system
reliability and performance. Thanks to the IU characteristic curve with
constant current limitation and simple switching between several
setpoints, the device is also suitable for charging batteries directly.
Another feature is the double short-circuit current to reliably trigger
fuses in the event of a short circuit. The DC series is equipped with this
option as standard, for the AC series it is available on request.
External monitoring or external control is possible with the signals fed
out at the remote signal connections. The external control unit PSC100
N1 is optionally available for this purpose. A system-side connection to
control rooms or PLC controls is also possible. The strict separation
between control and monitoring functions should be emphasized here.
Thanks to its good dynamic control characteristics for input voltage
changes and load jumps, this switched-mode power supply is superior
to line-commutated thyristor rectifiers for mains transients, frequency
jumps and dynamic loads.
