Battery Load Unit BLU220T

The Battery Load Unit – BLU220T is the stand-alone or a PC-controlled battery capacity test set, based on the state-of-the-art technology. Its design is using the most advanced power electronics solutions with coolers and fans integrated into device itself.

The BLU220T device is lightweight (15,1 kg / 33 lb.) and developed to meet a customer’s wide ranging test procedure requirements (standardized as well as customized). Using the BLU220T 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).

Discharging 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 case a battery remains connected to the load – by measuring and compensating the load current during the process.

The BLU220T device provides the discharge current of up to 340 A and may be applied to battery strings with up to 60 V voltage level.
