ESCRIPTION
Bonitron’s M3460 ride-thru voltage regulators provide protection from power quality events
for variable frequency drives (VFDs) that use a fixed rectifier and DC bus. The M3460UC
provides protection from short term full outages of up to 2 seconds with the addition of
Ultra capacitor storage system.
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 M3460 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.
