M3612EC Filter CapacitorM3612RC Common Bus Snubber

The M3612EC is a filter capacitor bank for a common DC bus drive systems. The drives can be either servo or variable frequency drives intended for use with common bus capacitors.

  • 7,000 - 28,000μF

The M3612RC Common Bus Snubber is a high frequency filter that limits spikes and ringing in DC bus systems caused by inverter switching, supply noise, bus reactance, and other sources. Limiting these spikes protects attached drives and power supplies, preventing premature failure.

  • Limit Spikes
