DV Power BLU200A

The DV Power BLU200A is a Battery Load Unit – BLU series is a standalone or PC-controlled battery capacity test set, based on state-of-the-art technology, using the most advanced power electronics solutions with coolers and fans integrated into the device. The BLU series devices are a lightweight solution for test engineers worldwide, developed to meet customers’ wide-ranging test procedures (standardised and customised).

Using a BLU device, the capacity test is performed in an accurate, user-friendly way in accordance to actual standards for battery testing (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 taking into account the load current during the process.

The BLU series devices provide the discharge current of up to 340 A and are applicable to up to 500 V battery voltages. When a required discharge current or power exceeds the capacity of a single BLU device, several BLU devices can be connected in parallel. Alternatively, External Load Units BXL series can also be used to increase the discharge B-BLUNS1-322-EN. 2019-04-10 2 capacity. Combined with Battery Voltage Supervisor BVS and Battery Voltage Recorders BVR, BLU series devices are a powerful tool that enables performing a detailed evaluation of batteries. An overview of the maximum currents for various battery voltage ranges, with a minimum achievable cell voltage of 1,75 V, is presented in the table below. Maximum currents available by using BXL series devices are also presented in the table
