- Fractional to 3kW Drives
- 0.6 Second 100% Outage
- Electrolytic capacitor energy storage reservoirs with soft precharge

The Bonitron S3534EC Ride-Thru System protects variable frequency drives (VFDs) from line sags and outages.

When full outage protection for up to 0.6second is needed, the S35340EC is the ideal solution for up to 3kW systems. The S3534EC stores energy in maintenance free electrolytic capacitor banks and releases it back into the drive’s DC bus when needed. This allows the drive to Ride-Thru events while maintaining motor speed and torque, without experiencing drive shutdown.

The S3534EC is a preengineered system with disconnects, displays, and all the hardware needed for a complete solution.
