Extra load units for TORKEL test system
TXL830, TXL850 and TXL780
Extra load units for TORKEL test system
DESCRIPTION
TXL
These resistive extra loads do not perform 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.
