ESCRIPTION
Bonitron’s M3534 Ride-Thru Voltage Regulator provides protection from power quality
events for variable frequency drives (VFDs) that use a fixed rectifier and DC bus. The
M3534R provides sag protection for up to 2 seconds at 50% line sag on all 3 phases. It
can also provide protection from short term full outages of up to 2 seconds with the addition
of storage systems, such as capacitors. The M3534B, in conjunction with a battery bank,
provides protection for up to 60 seconds during a full outage.
Industries with continuous processes can suffer huge losses from equipment downtime,
loss of production, or damaged product when VFDs trip on under-voltage conditions.
Traditional UPS solutions are connected in series, which decreases the overall drive
system reliability. All Bonitron Ride-Thru products connect in parallel with the drive, thus
increasing system availability and reliability.
The M3534 regulates incoming voltage to the DC bus of the variable frequency drive. This
allows the drive to “ride through” these events while maintaining motor speed and torque
without experiencing drive shutdown.
