Construction
The system consists of individual resistive and
reactive load banks, and a load connection
box factory mounted on a rugged structural
steel skid. All load bank exterior panels are
constructed out of aluminized steel for supe-
rior corrosion protection. Hot air exhaust is
vertical away from personnel.
Controls
The entire system is controlled by a rugged,
compact (7" x 7" x 2"), lightweight Hand Held
Controller. The controller is easy to operate
and load values are activated by pressing a
membrane style keypad. All resistive, reac-
tive, jog, and blower functions are displayed
on an LCD display. A hard wired E-Stop push
button is provided on the controller. The con-
troller communicates to load bank PLC via a
200' cable with an MS style connector.
Resistor Elements
The resistive elements are manufactured
from corrosion resistant chromium alloy wire
and are fully supported on stainless steel rods
for long life.
Reactive Elements
The reactive elements are non-saturating
single and 3 phase iron core reactors im-
pregnated with high dielectric varnish.
Cooling
The LPS resistive elements are cooled by two
integrally mounted fan motors each rated
10 HP, 460 VAC, 3 phase, 60 Hz.
Protection
The LPS features branch circuit fusing on
all load steps and overtemperature protec-
tion. Air switches on the fans are electrically
interlocked to remove load if air flow is not
sufficient to provide proper cooling.
NOTE Standard voltage is 480 VAC, 3 Phase, 60 Hz. Other
voltages and frequencies are available. Consult factory.
