TORKEL 840/860 Battery Load Units
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 different voltages. It features excellent discharging
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 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.
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 drop significantly for a
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 discharge test.
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.
