Bonitron’s Model M3534 series of DC Bus Ride-Thru Modules (RTM) provide protection from AC line voltage sags and outages for AC drive systems that use a fixed DC bus as with AC PWM VFDs. The Model M3534 series of DC Bus Ride-Thru Modules provides protection from line voltage sags or the momentary loss of one phase by temporarily storing energy internally and releasing it back into the DC bus when needed. This allows the drive to “ride-through” these events, maintaining motor speed and torque without experiencing drive shutdown.
