ELL-1005 Load Edge
High Speed, High Current Electronic Load
The ELL-1005 is a high current electronic load capable of 405A
loading and 1000W.
New design made this high current load in 1/4 of its predecessor
model.
This model is suitable for high current discharging test for
capacitors and batteries.
With its 50A/μs slew rate, this model is applicable to high speed
loading test.
Constant Current (CC), Constant Resistance (CR), Constant Voltage
(CV), Constant Power (CP), External Control mode, Dynamic loading,
Sequence mode, Short and Current limit functions.

Peak power
Newly invented "Extreme Power" technology allows this model to
operate at much higher power for the duration specified since this
technology manages Peak Power and Average Power.
Low voltage operation
There is no operating limitation by Loading Voltage since this
series sink load current as far as voltage difference exists.
Minimum operating voltage : 0.6A@405A , 0.3V@202.5A, 0.1V@67.5A
Parallel operation
Up to 5000W loading is possible by parallel operation (max. 2025A).
The ELL-1005 is equipped with various features suitable for
evaluation and inspection applications. External control mode (0 -
10V) can control load current externally, Current monitor for load
current monitoring (not isolated), GPIB as well as USB interface.

Master-Slave operation. One
master unit can control up to 4 units of slaves of same
voltage rating. For example: If the master unit is ELA-305
then ELA-155, ELA-305 or ELA-1005 may be connected as slave
unit. |
