DESCRIPTION APPLICATION EXAMPLE

The TORKEL™ 900 series is used to perform load/discharge testing The TORKEL is connected to battery, the current and the voltage

shorten the test time. Discharging can take place at up to 220 A,
and if higher current is needed, two or more TORKEL units or extra
load units, TXL, can be linked together. Tests can be conducted
at constant current, constant power, constant resistance or in
accordance with a pre-selected load profile.
Testing can also be carried out without disconnecting the
battery from the equipment it serves. Via a DC clamp-on probe,
TORKEL measures the total battery current while regulating it at
a constant level. Battery systems can be plus or minus grounded
or free floating.
The test results can be presented and edited on a PC using the
included PC software “TORKEL Viewer.
