Bonitron Undervoltage RideThru Solutions, also known as Uninterruptible Power for Drives, include a DC Voltage Regulator (M3534) that monitors the drive. If the drive voltage sags or disappears, the Voltage Regulator becomes active and provides power to the DC bus. This allows critical processes to never see the disturbance and can continue operating at full power. Thanks to Bonitron's parallel connection, very low standby power and long product life can be expected.
The M3534 Series is offered in two versions: The M3534R and M3534B.
The M3534R is a Voltage Regulator that protects drives and processes from 2-second power sags. It can also be used with energy storage, such as electrolytic or ultracapacitors, to protect from outages lasting up to 2 seconds.
The M3534B is a Battery Voltage Regulator that is used with energy storage, such as batteries, to protect drives and processes from outages lasting up to 60 seconds to allow time for generator startup. With seamless power transfer, the M3534B (with appropriate components - M3528 Charger and Batteries) allows seamless power transfer from the grid, to Bonitron, to generator.
For ratings above 85A or 60 seconds, see the M3460 Series.
