Megger BVM150 Battery Voltage Monitor
Order #: BVM150
Mfg #: CJ-59092
Product Highlights
The Megger BVM is a battery voltage monitor used for the capacity testing of large, industrial battery banks commonly found in electrical power sub-stations, telecom facilities, and computer data center UPS systems. When used in conjunction with a load device, such as the TORKEL unit, and test data management software, such as PowerDB and TORKEL Win, the BVM enables you to perform a completely automated battery bank capacity test, according to IEC test method. The test also meets NERC/FERC requirements.
The BVM is designed in modular form where one BVM device is used for each battery or 'jar' in the string to be tested. One BVM for each battery connects to the next in a 'daisy-chain' fashion (up to 2x120 units), thereby providing easy and economical expandability to meet the testing requirements for small to large battery bank systems.
Setting up the BVM system for a test is quick and easy. Each BVM unit is identical and can be connected in any battery test position, thus providing maximum flexibility and interchangeability of the BVMs. The BVM 'Auto Discovery' feature enables the host device to automatically determine the number of batteries under test and provide sequential identification of each BVM unit in the test string.
The BVM equipment is a battery cell/block voltage measurement system performed on battery banks. It can be used in conjunction with a load device such as the TORKEL. It can also be used to measure cell/block voltages from a PC with TORKEL Win or PowerDB. The BVM system is designed in a modular form where one BVM unit is used for each cell or block in the battery string to be tested. One BVM unit for each cell or block connects to the next in a daisy chain fashion. The included dolphin clip can easily be removed and exchanged with different styles of standard banana plug clamps and/ or extension cables to accommodate any battery connection requirement.
Automates battery voltage measurement during capacity tests. 'Daisy-chain' design allows expandability up to 2x120 cells. High accuracy and stability for precise data collection. Integrates with TORKEL Win and PowerDB Test Data.
Easy set-up with many options for connecting the BVM system to a battery bank.
