Optionally AC or DC powered
The Metropolis
®
AMU can optionally be AC powered or DC powered. However, the
realization of the power supply is slightly different.The unit has two -48V power inputs
and supports a full system load of 150W from a single 48V input. The Metropolis
®
AMU can only be AC powered by means of an external AC/DC converter.
DC power supply

AC power supply
As an alternative to the DC power supply, an AC power supply can be facilitated via
an external AC/DC converter.
The following external AC/DC converters are available:
•
AC/DC converter 90~230V 50~60Hz 75W (CC: 408965325)
•
AC/DC converter 90~230V 50~60Hz 120W (CC: 408965333)
•
AC/DC converter 90~230V 50~60Hz 240W (CC: 408991057)
Important! To operate the Metropolis
®
AMU AC powered, an external AC/DC
converter is required.
