The load may
be operated at
any given input
condition that
is within the
red line boundary.
For example:
If a 300 Volt source
is to be tested, select
the 300 Volt line (
blue )
and note the range
of current allowable
along that line.
In this example,
the load may be
operated at currents
from near zero to
a maximum of 16.6
Amperes @300V.
Refer to www.kepcopower.com/el-opcurve.pdf for operating curves of all EL models.
Operation at 400 Volts
valid until 12.5 Amps, which
is 5000 Watts, the maximum
power dissipation capability.
As current increases, voltage must be
lower to keep the power dissipation at
or below the upper limit of 5000 Watts.
This line represents the
minimum resistance of the load.
This line represents the maximum current
capability (420 Amperes). The line stops at
5.05 Volts because the lowest resistance
capability has been reached.
The EL Series is a line of modular air-
cooled, DC electronic loads used to test
power sources such as batteries, power
supplies, generators, chargers, fuel cells,
etc. Power ratings start at 1KW; standard
models have maximum test capabilities
of 50, 200, 400 and 600 volts. Individual
modules are capable of up to 5KW and
800 amperes (see chart). High current and
power operation are achieved via parallel
connection in a master/slave configuration.
The EL Series offers unique Functional
Modularity. Functional Modularity allows
the load to be retrofitted to increase load
power/current as required for undefined
future applications. Purchase the capability
needed today with assurance of future
power/current upgrades. The result is an
Electronic Load maximizing the most
important specification:
VALUE = $/Watt
When the requirements increase, the load
may be upgraded.
All EL loads operate as master or slave and
can come with or without front panel control
and readouts. Up to 15 additional loads
can be driven with one acting as a master.
INDIVIDUAL LOAD CHARACTERISTICS
• Base Unit - Includes front panel controls and
indicators for Amps, Volts and KW
• Computer-operated LabVIEW™ capable
• Constant current, voltage, power, resistance,
conductance and short circuit modes
• Readback voltage, current, power and load status
• USB and RS-232 are standard
• GPIB or Ethernet Control via single optional
interface card
• Comprehensive SCPI command set
• Monitor load current via computer or analog
output
• Use unique test patterns from an Arbitrary
Waveform Generator via the external analog
input
• Remote voltage sense eliminates error caused
by voltage drop in test leads
• Transient capability, 100 microseconds to 10 seconds
• Repeating transients, repeating every 100
microseconds to 10 seconds, from 2 to
10,000 times
• Programmable leading and trailing ramps on
output changes, from 100 microseconds to
10 seconds
SYSTEM INTEGRATION
IS SIMPLE
• Up to 60KW into one 8 ft. rack
• Control up to 15 slaves with
one master (75KW)
• Computer controlled and/or front
panel operation with display for
voltage, current, power and status
• Simple operation - no deep menus
to contend with
RELIABLE AND RUGGED
• High power semiconductors are
heat sinked for cool operation
• Very low internal resistance
ensures fast and clean switching
operation
• Power devices individually fused
for complete protection
• Internal thermal sensors ensure
uniform power distribution for
long reliability
• Isolated test bus allows a
wide range of source (DUT)
configurations
