MODULAR SMPS POWER PLANT
PUNCOM
offers
SMR-48V/33A
, a switch
mode rectifier module, designed to provide up to
33A of output current into a 48V nominal system
for
telecom,
datacom,
industrial
and
IT
applications. It Converts 150-275V AC input power
at 50 or 60 Hz into a highly regulated, filtered,
low noise and isolated 48V DC output. The unit is
designed for N+1 redundant configurations. Up to
eight rectifier modules can fit in a single 19” rack
to provide 231A of current in N+1 configuration.
Up to fifteen rectifiers can be configured in two
19” racks for a 462A ultimate capacity system in
N+1
configuration
using
one
control
and
supervisory unit (MiniCSU). The system can also be
monitored and controlled remotely through modem
or internet. The rectifier has been designed with a
“plug-and-play” feature i.e. when a rectifier module
is plugged into a live system the relevant system
parameters are automatically downloaded from the MiniCSU, making rectifier
replacement a completely hands-off operation. The unit is fully hot pluggable.
SALIENT FEATURES
 Hot Pluggable.
