DC Bus Energy Storage Solution – BOSCH KM 3300-T | KM3300 Series
Where This Product Is Used
The BOSCH KM 3300-T (Part No. 054915-103) is a DC bus capacitor module from the KM3300 series, engineered for energy buffering and voltage stabilization in high-performance servo drive and motion control systems. It is widely deployed in the following industrial environments:
- CNC Machining Centers – Stabilizes DC bus voltage during rapid axis acceleration/deceleration cycles, preventing drive faults and protecting spindle drives.
- Injection Molding Machines – Absorbs regenerative energy from hydraulic servo pumps, reducing heat dissipation and extending drive service life.
- Automated Assembly Lines – Provides ride-through energy during brief power interruptions, maintaining production continuity.
- Robotics & Multi-Axis Motion Systems – Buffers peak current demands across shared DC bus architectures, enabling coordinated multi-axis operation.
- Printing & Packaging Machinery – Smooths voltage transients caused by high-inertia web tension control systems.
- Semiconductor & Electronics Manufacturing – Supports precision motion stages where voltage ripple directly impacts positioning accuracy.

Application-Specific FAQ
Q: Is the KM 3300-T compatible with all BOSCH Rexroth DKS drive variants?
A: The KM3300 series is designed for use with BOSCH Rexroth DKS, HDS, and KDS series drives that share a common DC bus architecture. Always verify the bus voltage rating and connector type against your specific drive model before installation.
Q: Can this module be used as a standalone UPS for the drive system?
A: No. The KM 3300-T is a DC bus buffer, not an uninterruptible power supply. It provides short-duration ride-through (milliseconds range) and regenerative energy storage, not sustained backup power.
Q: What is the typical service life of the capacitor module?
A: Electrolytic capacitor life is temperature-dependent. Under rated operating conditions, BOSCH Rexroth capacitor modules are designed for a minimum 10-year service life. Elevated ambient temperatures significantly reduce this figure.
Q: Do you provide installation support?
A: Yes. Our technical team can provide wiring diagrams, parameter settings, and remote commissioning guidance. Contact us at support@konmask.com.
Q: Can I return the module if it does not fit my application?
A: We offer a 30-day return policy for unused, uninstalled modules in original packaging. Please contact us before returning any item.
