Application examples with TORKEL/
TXL systems
TORKEL and TXL can be combined into systems to match up for
different battery capacities. These resistive extra loads do not per-
form any regulating functions. They are designed for use together
with TORKEL Battery Load Units. Their purpose is to provide higher
load currents for use in constant current or constant power tests.
Together, TORKEL and the TXL Extra Loads form a system that can
discharge batteries with currents of up to several kA. TXL Extra
Loads are connected directly to the battery, and TORKEL measures
the total current using a clamp-on ammeter.
TXL Extra Loads are shut down automatically when TORKEL is
stopped.
