Battery Capacity Tester DV Power BLU220T

Battery systems must be reliable and provide power whenever it is required from them. When damaged they also present a safety risk. Batteries condition needs to be regularly inspected. The most reliable testing method is measurement of battery capacity performing the discharge test. The DV Power BLU100A, Battery Load Unit is an automated, reliable, and powerful tool for battery discharge test. 
The BLU220T is one of DV Power’s stand-alone or PC-controlled battery capacity lightweight (15,1 kg/33 lbs) test set, based on a state-of-the-art technology, using the most advanced power electronics solutions with coolers and fans integrated into device.  It can be used in a range of applications such as:  

• Power utility batteries monitoring tasks 
• Testing the power supply to circuit control and protection devices during power outages 
• Telecom standby power applications 
• For batteries requiring long-term discharge capabilities, etc. 

Intended use BLU220T

DV Power BLU220T is a powerful solution with maximum discharge power of up to 19,2 kW. It is applicable to any battery string such as Lead-acid, Li-Ion, Ni-Cd, with the battery voltage from 5,55 V up to 70,5 V and maximum discharge current up to 350A. Besides that, if higher currents are required BLU220T can be connected to the battery along with additional BXL-T. 
The user can select three discharge modes: 

• Constant current, 
• Constant power, 
• Constant resistance. 

Additionally, different battery duty cycles can be simulated using user-selectable discharge profiles. 
Model BLU220T is mainly used (but not limited to) telecommunication utilities. However, it can be used to any battery with voltage value not exceeding 70,5 V. 

How to use BLU220T?

Testing with the DV Power BLU220T allows you to test batteries online by using the optional current clamp, which means that you do not have to disconnect the batteries from the load. Combined with Battery Voltage Supervisor BVS and Battery Voltage Recorders BVR, BLU220T devices are powerful tool which enables performing detailed evaluation of batteries. 
DV Power Battery Load Unit, BLU220T, is connected to the battery with a set of current test leads of customizable length (3, 5, 10 m, etc). Optionally, voltage sense test leads of the same length can also be provided. 
After connecting the BLU220T to the test object, simply by choosing the type of test and presetting the necessary limits for battery type that is being tested the test is prepared to be started. Depending on the battery type, test current value, after a predefined time the result is one simple number, measured capacity expressed in Ah. If any of the predefined limits is reached before the time limit ends, battery is not able to provide the necessary power. 
DV Power Battery Load Unit BLU220T is testing the batteries in accordance with battery testing standards: IEEE 450-2010, IEEE 1188-2005, IEEE 1106-2015, IEC 60896-11/22, and other relevant standards.  

PC Software used with BLU220T 

Official DV-B Win software is also included in the purchasing price of the Battery Load Unit DV Power BLU220T. Using the software a test can be controlled, performed and observed from a PC (or notebook) and the results can be saved directly on a PC (or notebook). Using DV-B Win the results can be arranged and printed for a report. Supported formats are: 

• XLS 
• PDF 
• Word 
• RTF.
