The BXL Series of battery extra load units are designed as an additional load to be used with the BLU series instruments if a required discharge current or power exceeds the capacity of a single BLU device.
The BXL Series of devices have been designed using state-of-the-art technology and advanced power electronics engineering. The BXL Series are powerful devices providing high discharge currents (up to 310 A DC) applicable to up to 500 V DC battery system voltage levels. The BLU and BXL instrument combination enables capacity testing to be performed in an accurate, user-friendly way in accordance with battery testing standards (IEEE 450-2010 / 1188-2005 / 1106-2015, IEC 60896-11/22 and other relevant standards).
A BLU device (in a BLU-BXL system combination) ensures control of the discharge process. The BXL simulates a constant load during the discharge test. Its load parameter (resistance) can be set prior to the discharge test start. The BXL provides flexibility in selecting its load capacities and several resistances can be set for most commercial battery nominal voltage levels.
DV Power provides a 3-year warranty on all test instrumentation. This is a guarantee to our customers that they will receive the highest quality test equipment on the market.
