Superior Avtron quality combined with
simple operation and maintenance will
provide years of trouble free service.

Avtron’s extensive line of Load Bank and
Industrial Resis tor Products are solid
performers used throughout the world.

The Avtron Model LSV Load Bank is used for testing
high capacity power sources.

The Avtron LSV resistive load bank is ideal for testing high capacity generators or turbines.
Avtron is leading the industry by offering a high capacity load bank. This load bank is ideal for
permanent outdoor installation for routine load testing of standby diesel generating systems
or for factory production line testing of (UPS) Uninterruptible Power Supplies, turbines, or en­gine generator sets.

The LSV load bank is designed for permanent outdoor installation which features vertical air
discharge for installation in areas where space is at a premium such as the rooftops of high-rise
buildings. Weatherproof exhaust hoods provide maximum protection to the resistor cases and
blower assemblies.

Each load bank module is typically rated between 3 and 4.6 MW. Multiple modules are used when
tens or hundreds of megawatts are required. Voltages from 400 thru 600 VAC are available.

The LSV load bank incorporates 4, 6, or 8 independent resistive stacks. Each resistive stack
contains its own integral cooling fan. A hinged and lockable compartment houses the main
input load bus connections as well as load step contactors. The operator controls are housed in
a separate remote enclosure. The LSV features the latest load bank design and manufacturing
techniques to provide years of trouble-free service. Our commitment to customer satisfaction
assures quick delivery, easy installation, and simple operation and maintenance.

This load bank is ideal for high power resistive loading of generating systems in factory production
lines or test cells. It is designed for permanent outdoor mounting.

Specications subject to change without notice.

Construction

The load bank is fabricated from heavy gauge
formed steel and welded structural steel,
making a rigid, drip-proof structure suitable
for permanent outdoor mounting. Cooling
air for the resistive load elements is drawn in
from the bottom and exhausted out the top.
Weather-resistant exhaust hoods and welded
intake screens provide maximum protection
to the resistor cases and blower assemblies.
Structural extension legs are provided for
mounting the load bank at the proper field
elevation.

Resistor Elements

Avtron Helidyne™ load elements are helically
wound from nickel chromium resistance alloy
and are specially designed for high power
applications. The elements are fully supported
across their entire length with ceramic insula­tors on stainless steel support rods.

Control Power

The LSV requires control power of 120 VAC,
single phase, 60 Hz power (control trans­former optional).

Cooling

The resistive load elements are air cooled by
multiple integrally mounted blower motors.
The blower motors are controlled by motor
starter relays located within the load bank
and feature a time delay starting sequence
to reduce in-rush current. An external power
source rated 460 VAC, 3 phase, 60 Hz is re­quired to power the blowers. Motors rated
575 VAC, 60 Hz, 415 VAC, 50 Hz, or 380 VAC,
50 Hz are available as options.

Manual Controls

A rack-mounted control panel is provided for
remote mounting. Controls include POWER
ON-OFF switch, a POWER ON light, BLOWER
ON-OFF push buttons with a BLOWER FAILURE
light, OVERTEMPERATURE light, MASTER
LOAD ON-OFF switch, and individual load step
ON-OFF toggle switches which actuate the
load contactors located within the load bank.

Protection

Differential air pressure switches are provided
for each blower. Overtemperature protection
is provided via a thermal switch for each resis­tor stack. Should an air-loss or overtempera­ture condition occur, all load is automatically
removed. Fuses and motor-overload relays
also protect the blowers.
