Description

During a power outage, crucial telecommunication and radio equip-

ment must be kept operating by batteries. However, the capacity of

such batteries can drop significantly for a number of reasons before

their calculated life expectancy is reached. Battery capacity should

thus be checked to prevent expensive downtime in the event of a

power failure.

The most reliable way to determine battery capacity is to conduct

a discharge test. The TORKEL™820 features a unique design that

combines efficiency with portability. Using TORKEL 820 you can

discharge 24 and 48 V batteries at a current of 270 A, and 12V

batteries at 135 A. Moreover, two or more TORKEL 820 units and/

or extra load units, TXL, can be linked together if you need higher

current. Discharging proceeds at constant current, constant power

or constant resistance, or in accordance with a pre-selected load

profile.

The TORKEL 820 issues a warning and/or shuts down the test

automatically when a) the voltage has dropped to a certain level,

b) discharging has continued through a certain time interval or c) a

certain amount of capacity has been dissipated.

Application example

Testing can be carried out without disconnecting the battery from

the equipment it serves. Via a DC clamp-on ammeter, TORKEL820

measures total battery current while regulating it at a constant level.

The TORKEL 820 is connected to battery, the current and the volt-

age alarm level are set. After starting the discharge TORKEL820

keeps the current constant at the preset level. When the voltage

drops to a level slightly above the final voltage, TORKEL 820 issues

an alarm. The total voltage curve and the readings taken at the

end of the test are stored in TORKEL 820. Later, using the TORKEL

Win program, you can transfer these readings to your computer for

storage, printout or export. If your PC is connected to TORKEL 820

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.
