SPECIFICATIONS:
CONSTRUCTION: The load bank is contained in a rugged
aluminized steel enclosure, with two rigid and two lockable
swivel casters mounted at the corners, and four lifting handles
provided for simplified handling.
CONTROL POWER: Control power is derived from an exter-
nal 120 volt, single phase, 60 Hz power source. A line cord
is included with the load bank for quick disconnect.
BLOWER: A heavy duty, reliable, industrial blower is used
for cooling the resistive elements. This 1/4 HP device oper-
ates from the same 120 volt, single phase, 60 Hz power
source as the load bank control circuit.
RESISTIVE ELEMENTS: Made of a chromium
alloy, the resistive elements are specially
wound and continuously supported
in the cooling air stream. They are de-
signed to operate at one half of their
rated temperature rating for more
stable loading and longer life without the need for a cool
down period.
CONTROL PANEL: It includes a POWER ON-OFF switch,
a power status indicator light, an ON-OFF switch for each
load step, a MASTER LOAD ON-OFF switch for applying
or removing all selected load steps, and a BLOWER FAIL
indicator light.
PROTECTIVE FEATURES: The control circuit is fuse pro-
tected and the load circuit is disabled by a differential
pressure air switch if insufficient cooling air is detected.
WEIGHT: Approximately 160 lbs. [73 kg]
