|*Portable Electronic DC load, 16-28KW by DV Power is the model series BLU. With battery bank input voltage range of 5.25V to 500V, max current absorption of 200A (120A for 125 VDC substation bank), plus more current by adding smart slave units BXL, and weight of under 32lbs or 42lbs, this is the most powerful, lightest DC load on the market. DV Win software controls it and archives results for initial bank acceptance, and aging comparison. BLU200A brochure [click for BLU200A] or BLU360V brochure [click for BLU360V] for model that covers 10V to 500VDC inputs. Latest model BLU480V extends voltage input range to 650VDC for 480V bank testing.
In fall 2019 a new C’ series of BLU will be available handling up to 800 VDC input, having a more ergonomic viewing angle and actually being able to discharge down to 0V for safely preparing batteries prior to re-cycling. [Click for new BLU500C model pdf, as a sample]
|*Cell by Cell voltage scanner, model BVS by DV Power that is used in conjunction with the DV Power load above or other loads on the market. Maximum 127 cell capacity and uses CAT data cables between modules and connects short fused wires with clips to the battery cell terminals. IT provides monitoring during discharge on PC software such that histogram graph during and after discharge easily reveals the weakest cells. It can also be put in a mode to stop the test when a cell hits a certain threshold voltage. THE BVS report also measures cell resistance and inter-cell (strap) resistance when operated with the BLU. BVS [click for BVS]TESTING NOTE: The combination of BLU DC Load and scanner above provides a true load capacity test as required by NERC, and adds the troubleshooting power of the scanner, to make the best and most economical capacity test system available. It is best for the bank to be disconnected from its typical purpose for a few hours and must be charged back up before relying on it for back-up (its typical purpose). Often a substitute bank is made available or bank under test is part of a dual bank connection in the sub-station or UPS room.|
|*Battery Voltage Recorder, by DV Power, the BVR is simple to use to read cell voltages and record all cell voltages in a bank for a once through check , or as a multiple scan manual recording of each cell during a discharge test. BVR [click for BVR]
