TORKEL 840/860 Battery Load Units
FEATURES AND BENEFITS
■ Batteries can be tested “in service”. TORKEL will adjust
to include the load current in the test parameters.
■ User adjustable alarm and shutdown points to avoid
excessive discharge.
■ No loss of test data in the event of a power loss during
testing.
■ Easily expandable for larger battery banks using TXL
extra load units.
■ Can be used “stand alone” or with a PC running
TORKEL WIN Software.
