Battery Load Units
Batteries in power plants and transformer substations must provide the equipment they serve with standby
power in the event of a power failure. Unfortunately, however, the capacity of such batteries can drop significantly for a number of reasons before their calculated life expectancy is reached. This is why it is so important
the check batteries at regular intervals, and the only reliable way of measuring battery capacity is to conduct
a discharge test.
TORKEL 840-UTILITY™ is used for battery systems ranging from 12 to 250 V – often encountered in switchgear and similar equipment. Discharging can take place at up to 110 A, and if higher current is needed, two or
more TORKEL 840™ 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.
TORKEL 860-MULTI™ is designed primarily for people who travel from place to place to maintain battery systems
having different voltages. It features excellent discharging capacity plus a broad voltage range and outstanding
portability – a unique combination.
TORKEL 860™ is used for systems ranging from 12 to 480 V, and discharging can proceed at up to 110 A.
If higher current is desired, two or more TORKEL 860™ units or extra load units, TXL, can be linked together.
Discharging can take place at constant current, constant output, constant resistance or in accordance with a
pre-selected load profile.

TORKEL 860 and the extra loads TXL 870
Testing can be carried out without disconnecting the battery from
the equipment it serves. Via a DC clamp-on ammeter, TORKEL
measures total battery current while regulating it at a constant level.
1. Connect TORKEL to battery.
2. Set the current and start discharging. TORKEL keeps the
current constant at the preset level.
3. When the voltage drops to a level slightly above the final
voltage, TORKEL issues an alarm.
4. If the voltage drops low enough so that there is risk of deepdischarging the battery, TORKEL shuts down the test.
The total voltage curve and the readings taken at the end of
the test are stored in TORKEL. Later, using the TORKEL Win
program which runs on a PC under Windows®, you can transfer
these readings to your computer for storage, printout or export.
If your PC is connected to TORKEL during the test, TORKEL Win
builds up a voltage curve on the screen in real time and
displays the current, voltage and capacity readings.
You can also control the test using TORKEL Win.

Extra Loads TXL850 and TXL870
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.
TXL850 is intended for 48 V systems. The resistor packages
in these units are divided into three parts, and the user determines
how many are to be connected. TXL Extra Loads are connected
directly to the battery, and TORKEL measures the total current
using a clamp-on ammeter.
TXL870 is intended primarily for 125 and 240 V battery
systems. Here, the resistor package is divided into two parts.
At 125 V, you can choose between connecting one or both of
them. At 250 V, both are connected in series.
TXL Extra Loads are shut down automatically when TORKEL
is stopped.
Extra Load TXL850
Used when higher current is desired for batteries of up to 48 V.
Here, a DC clamp-on ammeter must be used to enable TORKEL
to measure the total current.
