LOAD CUBE R
2500KW Load Bank System
The Load Bank is a completely self-
contained, freestanding unit which
includes all resistive load elements,
load control devices, load element
branch circuit fuse protection, main
load bus and terminals, cooling system,
control power supply, unit controller and
malfunction detection system and type
enclosure.
System Protection
Sensors, alarms (alarm message on
remote operator interface terminal),
lock-outs as appropriate, for the
following:
• Fan failure, each of two fans
• High exhaust temperature, each of
two fans
• High intake temperature
• High interior temperature, sensed at
three points
• Louver open/closed, each of eight
louvers
