ASCO 5600 User Manual
ASCO® Avtron 5600 Load Bank
The ASCO Model 5600 (formerly Avtron K580/K575A) Load Bank is a AC resistive, trailer
mounted unit designed for outdoor use when up to 1250 kW is required.
The ASCO Avtron 5600 load bank (part of the 5000 series trailer load bank product range)
features the most comprehensive innovations in both design and technology.
Load Bank Ratings
Standard capacity ratings of:
• 1000 kW
Standard load step resolution of 5 kW.
Standard three phase voltage ratings of:
• 240/480-60Hz
Please consult factory for non-standard ratings.
• 1250 kW

Blower Motor Control
The blower connection is factory wired to
the main load bus. Provisions for an external power source are also provided.
An integral 120V, 1 Phase, 60 Hz control
power transformer is provided for control
circuit operation
Cooling System
Approximately 23,000 CFM cooling is
provided by integral TEFC or TEAO motor
which is direct coupled to the cooling fan
blade.
The fan motor is fully protected with fuses,
motor starter contractor, and overload relay.
Operator Controls
The standard load control for the 5600 is a
local manual 19" rack mount panel. Controls
include: Power On/Off switch, Blower Start/
Stop push buttons, Master Load On/Off
switch, and Individual Load Step switches.
Visual indicators include: Power On, Blower
On, and Blower/Air Failure.
Digital Metering
Advanced Digital Monitoring System
(ADMS) is provided for display of Volts,
Amps, Frequency, and kW. ADMS also
includes Data Logging Software.
Construction
The 5600 is constructed using heavy
gauge aluminized steel per ASTM A463. It
is designed for continuous outdoor weatherproof operation. Forklift channels are
provided in the base for lifting.
All exterior fasteners are stainless steel. The
main input bus, load step relays, fuses, and
blower/control relays are located in the main
enclosure.
Load Connections
Easy access load connection box with bus
bars for load power. Bus bars have standard
NEMA hole patterns.
Finish
The 5600 has a high quality baked polyester
powder coated finish with a film thickness of
2.8 +/- 0.4 mils per coat. The standard color
is gray (ANSI 61).
Two Year Warranty Included
The equipment is covered by an industry
exclusive 24-month parts and labor warranty.

Resistor Elements
The ASCO Avtron brand load banks use helically wound chromium alloy Helidyne elements.
Elements are fully supported across their entire
length by segmented ceramic insulators on
stainless steel rods. These elements are designed
to operate at approximately 1/2 of their maximum
continuous wire rating.
Elements are positioned within the cooling
airstream for optimal performance. Changes in
resistance due to temperature are minimized by
maintaining conservative watt densities.
The overall load tolerance of the 5600 load bank
is -0, +5%. This ensures that advertised kW is
delivered at rated voltage.
The elements are continuously rated at the
specific voltage. Tests at lower voltages, with a
corresponding reduction in overall rating, may
be carried out.
Safety Features
A differential pressure switch is interlocked with
the load application controls to prevent load
from being supplied if cooling air is not present.
An overtemperature switch is provide to sense the
load bank exhaust. The switch is interlocked with
the load application controls to disable load from
being supplied if an over-temperature condition is
present.
The fan motor is protected with fuses and
overloads.
Major fault protection is provided by branch
circuit fuse protection. Fuse protection is
provided on all load steps.
The exterior of the load bank has appropriate
warning and caution statements on access panels.
Internal access is restricted by bolt on exterior
panels.
The air intake on the 5600 is designed to prevent
objects greater than 0.50″ diameter from being
ingested into the unit.
Horizontal air discharge is provided and exhaust
air is directed downward away from personnel.
Ambient Temperature and Humidity
The 5600 load bank is designed for continuous
duty cycle with no limitations. The ambient temperatures range is -20°F to 120°F (-28°C to 50°C).
