DESCRIPTION
UNIPOWER's UNIFLEX
provide the ultimate flexibility in combining
fuses, circuit breakers and/or an LVD in a dual
(A/B) panel. A GMT section provides 10 fuses
and a circuit breaker section, 1-6 breakers.
A low-voltage disconnect section is
configured at the factory for either battery
or load disconnect and can have an optional
bypass switch. A battery circuit breaker is
standard.
Each A and B section has an LED alarm
indicator and Form C relay contacts.
The A and B Sections are isolated and can be
configured independently at the factory for
12, 24 or 48 VDC, positive or negative ground.
The panels are only one mounting position
(1.75 inches) high and come with brackets
that permit mounting in either a 19- or
23-inch relay rack. They can be mounted
from the front of the rack with offsets every
quarter-inch from front to back to align with
existing rack mounted equipment.
