NAT-RPM-AC600

NAT-RPM-AC600

The NAT-RPM-AC600 is a power distribution module especially designed for MTCA.4.1
applications to be used in the rear card carge of an MTCA 4.1 system. By the MTCA 4.1
standard the rear power modules (RPMs) differ in form factor and use from a standard
MTCA power module.

The NAT-RPM-AC600 provides Management and Payload Power for up three eRTMs and
a positive (VV+) and negative supply (VV-) for up to twelve uRTMs in a
MicroTCA.4 chassis equipped with an RF-Backplane. The VV+ and VV- voltages are
adjustable in a wide range.

The NAT-RPM-AC600 offers power conversion from universal line input (85 to 265 VAC)
and feeds up to 16 independent power channels for RTMs. It supplies backup power
for other power modules (Shared Management Power, SMP) within the system.
It is available as double-width, full-size module.
