Megger TXL830 Load Unit For Use With Torkel Systems

The Torkel TXL830 is designed to provide higher load currents when used with TORKEL battery load units.

Reference BS-59003

Brand Megger

NB: The Megger TXL830 (BS-59003) is supplied without accessories.

The Megger TXL830 load unit is 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 clamp-on ammeter.

The Torkel TXL830 extra load unit is shut down automatically when TORKEL is stopped.
