Low Voltage Disconnect (LVD) option

Powerware Data-Voice-Video Power Solutions may be fitted with one or more Low Voltage
Disconnects (LVDs). The way LVDs can be connected is determined by the type of DC power
system:
In DC power systems without integrated batteries the LVD(s) can be connected either as
•
load or battery disconnect(s).
In DC power systems with integrated batteries the LVD(s) can only be connected as a
•
battery disconnect.
LVDs have two purposes:
to protect a VRLA battery from deep discharge and premature failure, and/or
•
to reduce the load on a battery under discharge so that high priority equipment operates
•
for a longer time after an AC failure.
The system controller has two LVD control channels (LVD1 and LVD2.) These can be set to
disconnect at specified voltages or can be set to disconnect a specified time interval after an
AC fail. Both channels reconnect the battery or load equipment when the AC supply is
restored.
Refer to the system controller handbook for information on how to configure the LVD
channels.

External current shunts/sensors option

Various models of external current shunts/sensors are available for use with the Powerware
Data-Voice-Video Power Solutions to measure battery and/or load currents. The Powerware
CS04-A11 current sensor is also available to measure currents in larger systems. See details
on page 67.
External current shunts/sensors are connected to the I/O board or to a Powerware SiteSure-
3G module.
