ESCRIPTION
Variable Frequency Drives (VFDs) are commonly used in industry to improve control over
continuous process applications, such as in the textile and semiconductor industries,
where very accurate motor speed control is required. Unfortunately, these systems are
quite susceptible to problems caused by fluctuations of incoming power, such as AC line
voltage sags or outages. Long downtimes as well as large and costly production losses
have been experienced due to VFD shutdowns caused by these occurrences.
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 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.
The majority of AC line voltage fluctuations that occur in three-phase distribution systems
have a magnitude (decrease from nominal voltage) of less than 50% and duration of less
than 2 seconds. The model M3534R DC Bus Ride-Thru Control module provides
sufficient ride through capability to handle these types of voltage sags.

The M3460R 230-480VAC Ride-Thru Module is designed to maintain inverter bus
under 3-phase 50% sag conditions with multiple cabinet systems rated up to 1200kW.
The M3460B 350-540VDC Ride-Thru Module is designed to boost a battery bank up
to inverter level under 100% outage conditions.

M3528 is a voltage and current limited power supply used to charge electrical energy
storage devices such as battery banks or ultracapacitor reservoirs for industrial voltage
levels of 208 - 480VAC. User inputs allow for remote enable and second setpoint
charging for battery equalization.

M3628 Modules deplete hazardous stored energy in Ultra Capacitor Ride-Thru
Systems. Standard packages are typically sized to discharge the voltage to 50V in 1
minute.
