BFAS

Relying on the proven relationships between current and impedance, the BFAS battery monitor, detects battery failures, DC filter failures, inverter shut down and transfers to bypass.

Battery Failure Alarm Systems has developed a revolutionary battery monitor that continuously checks on-line UPS system batteries and dependably signals a local and/or optional remote alarm anytime the battery is unable to perform. This unique monitor does not require a battery discharge or system down time to effectively monitor single or parallel strings. This monitor is installed easily, totally non-invasive of the UPS. Installation is done without disruption to the load or battery system. The normal open alarm contacts can be used to activate a modem or signal a remote monitor. Once installed, this battery monitor will sound an alarm when conditions indicate that the battery systems cannot support the load should a power failure occur.

DIMENSIONS 8.4" (W) X 10.4" (H) X 7.13" (D)
WEIGHT 6.5 LB.
OPERATING TEMPERATURE RANGE 0 - 40 DEGREES C.

As a battery develops problems, its impedance will rise and less AC current will flow. AC current is a normal, though minor, component in the charging circuit of the battery systems.
This monitoring instrument is adjusted to alarm at a low current threshold, allowing time for pre-emptive battery service to replace the failed cell or battery before the system fails.
DC filter capacitors are monitored via a high current alarm set-point. As DC filter capacitors deteriorate, there is a rise in AC current. The BFAS Monitor will sound an alarm that will prompt replacement of the DC filter capacitors before system performance is compromised.

Without shutting down your system, installation is simple and non-invasive.
