Description

The BECKHOFF C9900-U332-0010 is a high-reliability battery pack designed specifically for use with Beckhoff Industrial PCs (IPCs) equipped with a 24 V DC power supply and integrated Uninterruptible Power Supply (UPS). This external backup energy storage device ensures continuous system operation, controlled shutdowns, and data preservation during unexpected supply voltage interruptions or mains failures.

Constructed within a durable metal housing, the BECKHOFF C9900-U332-0010 is engineered for straightforward mounting on standard DIN rails. The unit features dual 12 V batteries connected in series to provide a nominal output of 24 V DC with a 1.2 Ah capacity. Designed using Valve Regulated Lead Acid (VRLA) Absorbed Glass Mat (AGM) technology, this maintenance-free assembly provides stable, long-term standby power in demanding industrial automation environments.

Features

• Nominal output voltage of 24 V DC via an internal series connection of two 12 V battery cells.
• Nominal capacity of 1.2 Ah based on a standard 20-hour discharge rate.
• Integrated 9 A PTC thermistor element for reliable overcurrent protection.
• Maintenance-free battery design using proven VRLA AGM (Valve Regulated Lead Acid with Absorbed Glass Mat) technology.
• Robust steel housing configuration optimized for mechanical stability in high-vibration applications.
• Integrated DIN rail mounting bracket compatible with standard TS35x15 2.3 profiles.

Applications

• Backup power buffering for BECKHOFF Industrial PCs and Embedded PCs with integrated 24 V UPS systems.
• Prevention of file system corruption and data loss in automated control systems during brownouts and power failure.
• Emergency shutdown sequences for industrial machinery, material handling equipment, and manufacturing lines.

Installation Guidelines

1. Ensure the system control cabinet power supply is fully de-energized before beginning physical installation.
2. Check the BECKHOFF C9900-U332-0010 housing for signs of transport damage before mounting.
3. Mount the battery pack vertically onto a clean, grounded standard TS35x15 2.3 DIN rail inside the control cabinet.
4. Provide sufficient clearance around the ventilation openings to prevent heat buildup and maximize battery service life.
5. Connect the output wiring to the integrated UPS terminal on the Industrial PC, verifying correct 24 V DC polarity.
6. Secure all electrical connections and ensure the PTC overcurrent protection path is clear before energizing the charging circuit.

Replacement Recommendations

Lead-acid batteries decay over time depending on ambient operating temperatures and the frequency of charge/discharge cycles. For system availability, inspect the capacity of the BECKHOFF C9900-U332-0010 during scheduled maintenance intervals and replace the unit proactively every 2 to 5 years, or immediately if the charging system reports a failing battery test.
