DESCRIPTION
The SEI DC-UPS 24VDC is a compact unit designed to service a wide range of
customer equipment requiring battery-backed 24 VDC power. The DC-UPS
provides 125 Watts (4.5A), 250 Watts (9.0 Amps) or 320W (11.5 Amps) of rectifier
power. The distribution is provided on the right side of the unit. Commercial power
is applied to the left side of the unit. The SEI DC-UPS can be mounted on a wall or
on a 19-inch rack. Optionally, SNMP communications via the Power Management
Package is available. Also, an optional Alarm Contacts Board is available.
Three output distribution modules are available. The ‘M’ module contains two,
individually fused 8-pin Molex
Minifit
connectors. The ‘A’ module contains
two, individually fused 2-pin AMP
Mat-N-Lok
connectors. The ‘P’ module
features two sets of individually fused 10-32 studs. Customer-specified output
modules are available.
The DC UPS comes equipped with field replaceable, non spillable, sealed lead
acid battery packs. Circuitry within the DC UPS monitors and periodically tests
the condition of the batteries and displays the results via external LED’s as well as
over the network, when equipped with the optional Power Management Package.
The DC UPS also utilizes a Low Voltage Disconnect, (LVD), circuit that prevents
damage to the Battery Packs during an extended AC outage
