The Avtron Model LSH Load Bank is designed for
permanent outdoor installation.
The Avtron LSH Load Bank is designed and built to incorporate the latest, state-of-the-art load
bank features. This model requires no cool down period after load is removed. The contactors
are housed in a therm ostatically controlled heated enclosure for protection against condensation related problems. The LSH load bank is used in the generator and UPS industries. This unit
is designed to be permanently mounted for dedicated, on-site testing.
The LSH load bank contains resistive elements and a blower motor in a rigid structure of
formed heavy gauge aluminized steel. Designed for outdoor installation, the load bank utilizes
a fixed louver on the exhaust opening to protect the motor and resistive elements from the
weather.
A remote control panel is provided for load bank operation and includes the necessary controls
and status indicators.
Avtron’s extensive line of Load Bank and
Industrial Resis tor Products are solid
performers used throughout the world.

Specications subject to change without notice.
Construction
The load bank enclosure is constructed of
heavy gauge aluminized steel. A fixed louver
is provided on the exhaust opening. Permanent base has built-in forklift channels
and is designed for outdoor mounting on
floor, roof, or concrete pad. Contactors are
protected in a thermostatically controlled,
heated enclosure.
Resistor Elements
The fully supported Helidyne™ resistive
elements are designed by Avtron and
manufactured of a corrosion resistant
chromium alloy wire.
Control Power
The unit requires control power of 120 volts,
single phase, 60 Hz. (Control power transformer optional.)
Cooling
The resistive elements are air cooled by an
integrally mounted 3 phase blower motor.
No additional cooling period is required when
load is removed.
Controls
The 19" [482.6] rack mounted control panel is
provided loose for remote mounting (control
panel enclosure is optional). Controls include
a POWER ON-OFF switch, a CONTROL POWER
light, BLOWER ON-OFF push buttons with
a BLOWER POWER light and AIR FAIL light,
MASTER LOAD ON-OFF switch, and individual
load step ON-OFF toggle switches.
Optional Digital Metering
Avtron Advanced Digital Monitoring System
(ADMS™) is provided for display of Volts,
Amps, Frequency, and KW. ADMS™ also
includes Communicator EXT™ Data Logging
Software.
Protection
The LSH load bank features branch circuit
fusing on all load steps and overtemperature
protection. A differential pressure air switch
on the blower is electrically interlocked to
remove the load if the airflow is not sufficient
to provide proper cooling.
