BATTERY LOAD UNITS – BLU-K SERIES

 

The BLU-K Battery Load Units is a series of affordable capacity test devices designed with portability and user-friendliness in mind. Implementing the most advanced power electronics solutions, a significant reduction in weights and dimensions is achieved compared to the traditional, stationary load units.

Besides the up-to-date design solutions, the series meets a customer’s wide ranging test procedure requirements (standardized as well as customized). Using a BLU-K device, the capacity test is performed in an accurate, user-friendly way in accordance with the battery testing standards (IEEE 450-2010 / 1188-2005 / 1106-2015, IEC 60896-11/22 and other relevant standards). The crucial test parameters (string voltage, discharge current / power / resistance, time and calculated capacity) can be monitored in real time on a 4×20 LCD screen.

The capacity test/discharge can be performed at constant current, constant power, constant resistance or in accordance with a pre-selected load profile. The discharge test can be conducted even in a case a battery remains connected to the load – by measuring the load current during the process.
