DESCRIPTION
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 dif
capacity plus a broad voltage range and outstanding
portability – a unique combination.
The TORKEL 860 is used for systems ranging from 12 to
480 V, and discharging can proceed at up to 110 A. If
higher curr
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 preselected load pr
ferent voltages. It featur
ent is desired, two or more TORKEL 860 units,
ofile.

Application examples with TORKEL/TXL systems
TORKEL and TXL can be combined into systems to match
different battery capacities. Below are two examples. Other
combinations can be found in the section called
TORKEL/TXL System examples.

extra load TXL unit
APPLICATION
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 dr
number of reasons before their calculated life expectancy
is reached. This is why it is so important to check batteries
at regular intervals, and the only reliable way of measuring
battery capacity is to conduct a dischar
op significantly for a
ge test.

• 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 clampon ammeter.
• TXL Extra Loads are shut down automatically when
TORKEL is stopped.
