Megger TXL Extra Load Units for TORKEL Battery Test Systems

Overview

The Megger TXL extra load units are designed to work together with TORKEL battery load units, providing higher load currents for constant-current and constant-power battery discharge tests. The TXL units connect directly to the battery and do not perform any regulating functions of their own. The TORKEL reads the total battery current through a clamp-on ammeter and holds it at a constant level, and when the TORKEL stops, its TXL STOP output shuts the TXL units down. Combined, a TORKEL and its TXL units can take a discharge test to several kA.

Key features of the Megger TXL extra load units

• Add load current to TORKEL systems for constant-current or constant-power tests
• Five models from 28 V / 300 A (TXL830) up to 480 V (TXL890), to match the battery bank voltage
• Connect directly to the battery; TORKEL measures total current with a clamp-on ammeter
• Units can be linked together for higher combined discharge current
• Automatic overload protection for safe operation
• Support grounded or floating battery configurations

TXL extra load battery testing applications

The TXL extra loads are used with TORKEL battery testers for capacity and discharge testing of large stationary battery banks in substations, telecoms and UPS installations, where the required load current exceeds what the TORKEL can supply alone. Combining TORKEL with one or more TXL units delivers the high discharge currents needed for big battery strings.

TXL models and ratings

• Megger TXL830: 28 V DC max, 300 A, 8.3 kW; selector 0.275 / 0.138 / 0.092 Ω
• Megger TXL850: 56 V DC max, 300 A, 16.4 kW; selector 0.55 / 0.275 / 0.184 Ω
• Megger TXL865: 260 V DC max (98 A max at 260 V), 117 A, 25.5 kW; selector 2.65 / 5.05 / 0.12 Ω
• Megger TXL870: 280 V DC max (56 A max at 280 V), 112 A, 15.8 kW; selector 4.95 / 2.48 / 1.24 Ω
• Megger TXL890: 480 V DC max (32 A max at 480 V), 62 A, 15.4 kW; selector 14.10 / 7.05 / 3.52 Ω

All five ratings are taken from the Megger TORKEL 900-series datasheet V12 (PDF)PDF. Choose by battery voltage first: the TXL830 and TXL850 are for low-voltage, high-current banks, while the TXL865, TXL870 and TXL890 cover higher-voltage strings up to the 480 V limit of the TXL890.

Why buy the Megger TXL extra load units from MME in the UAE

Tell MME the battery voltage, cell count and the discharge current you need, and we will tell you which TXL model and how many units to add to your TORKEL, then quote.
