- for Existing M3460R Modules-

The M3460B4 Battery Regulator Ride-Thru Module, in conjunction with a backup battery bank, provides protection from AC line voltage sags and/or outages for AC drive systems that use a fixed bus as with variable frequency drives (VFDs). VFDs are commonly used in industry to improve control over continuous processes where highly accurate motor speed control is required. Unfortunately, VFDs are quite susceptible to problems when fluctuations in incoming power occur.

One solution to this problem is to support the drive system’s fixed DC bus with a string or bank of backup batteries. However, this solution is not without its own problems. When using batteries for backup in this fashion, the charge voltage of the battery bank cannot exceed the DC bus voltage. Then, when the batteries are loaded supporting the DC bus, their voltage drops and quickly becomes too low to be useful.

Bonitron’s M3460B4 Battery Regulator Ride-Thru Module solves the “voltage drop” problem associated with battery banks in backup situations. The Ride-Thru module regulates the battery bank voltage, boosting it as it drops. This is done by temporarily storing energy in specialized “boost” circuits and releasing it into the DC bus as needed.

Bonitron’s M3460C is an enclosed Super Capacitor energy storage module. By adding the M3460C to a M3460 Ride-Thru module’s energy storage capability, a 100% outage for a full 1/2, 1, 2, or 3 second spec can be achieved.
