Megger BVM300 Battery Voltage Monitor

The Megger BVM300 Battery Voltage Monitor is a battery voltage measurement device that is 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 BVM300 enables to perform a completely automated battery bank capacity test, according to IEC test method. The test also meets NERC/FERC requirements. The BVM300 is designed in modular form where one BVM300 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, thereby providing easy and economical expandability to meet the testing requirements for small-to-large battery bank systems.

The BVM300 includes a dolphin clip that can be easily removed and exchanged with different styles of standard banana plug clamps or extension cables to accommodate various battery connection requirements. Set up is fast and simple using the BVM. Each is identical and can be connected in any battery test positions. Up to 120 of these products can safely be daisy-chained in a single battery bank under test. The last dolphin clip in the chain should be connected to the positive battery pole of the last battery in the bank. When used together with TORKEL the voltage will be logged through the complete discharge test.
