- 75 to 1350kW Drives : 3 Second 100% Outage -

The Bonitron M3460UR Ride-Thru Modules provide protection from line voltage outages and power sags for 208 - 600VAC variable frequency drives (VFDs) that use a fixed rectifier and DC bus.

Industries with continuous processes can suffer huge losses from equipment downtime, loss of production, or damaged product when VFDs trip on undervoltage conditions. While many drives claim to have ride through capability such as auto restart or kinetic buffering, none are able to maintain complete control over the motor as called upon by the process during a complete loss of power.

While the Bonitron M3460R is a small and cost effective method of protecting drives from voltage sags up to 50%, some sags are greater in depth. Some feeds with automatic re-closure systems may have up to 2 second complete outages.

The M3460UR provides sufficient Ride-Thru capability to handle these deep sags and outages by storing energy in ultra capacitor banks and releasing it back into the drive’s DC bus when needed. This allows the drive to ride through these events while maintaining motor speed and torque without experiencing drive shutdown.

The M3460UR is the most cost effective product to ride through short term outages with drive systems ranging from 75 - 1350kW. Adding a M3460UR to a fixed bus drive allows the system to surpass SEMI-47 and 100% outage specifications.
