18 Phantom Power Supply- RB-MSP6
18 RB-MSP6 6 Way +48V Phantom Power Supply
Introduction
Fig 18-1: RB-MSP6 Front Panel
The RB-MSP6 is a 1U rack-mount phantom power supply, designed to
be used in conjunction with up to six RB-MS4X3s, providing mains input
redundancy to ensure the target microphones remain powered in the event
of a single mains failure.
Two mains AC inlets power separate 48V supplies that are diode fed to
six locking DC connector outputs. Each output connector is individually
protected with a resettable fuse rated at 50mA, so a fault on one output
will not affect the others.
Should either of the 48V supplies fail, or if their AC power input is removed,
the corresponding red front panel LED will extinguish, and a relay alarm
output is provided on the rear panel D-Type.
