TORKEL 900-series Battery Load Unit TORKEL 900-seriesBattery Load Unit ■ Batteries can be tested in service ■ Dynamic discharge technology - full power at all voltages ■ Safety in all details, e.g. detection of blocked airflow ■ Real time monitoring during test ■ Quick report ■ Easily expandable for larger battery banks using TXL extra load units ■ BVM cell monitor control integrated in the system DESCRIPTION The TORKEL™ 900 series is used to perform load/discharge testing which is the only way to determine battery systems actual capacity. Together with the optional cell voltage logger, BVM, connected directly to the TORKEL 900, it becomes a complete, stand-alone, discharge test system. TORKEL comes in three models, 910, 930 and 950, see table below. The high discharge capacity of TORKEL gives the opportunity to shorten the test time. Discharging can take place at up to 220 A, and if higher current is needed, two or more TORKEL 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. Testing can also be carried out without disconnecting the battery from the equipment it serves. Via a DC clamp-on probe, TORKEL measures the total battery current while regulating it at a constant level. Battery systems can be plus or minus grounded or free floating. MODEL OVERVIEW APPLICATION EXAMPLE The TORKEL is connected to battery, the current and the voltage alarm levels are set. After starting the discharge, TORKEL keeps the current constant at the preset level. When the voltage drops to a level slightly above the final voltage, TORKEL issues an alarm. If the voltage drops so low that there is a risk for deep discharging the battery, TORKEL shuts down the test. If the power supply is interrupted the test will continue when power is restored. All values are stored in TORKEL and can easily be transferred via an USB-stick to a PC for evaluation and print out. Separate sensing cables (dashed lines) should be used to get accurate voltage measurements to offset the voltage drop caused by long current cables and/or high current.
