Features:

  • Provides Reliable High-Density Power Distribution For Trusted® Systems
  • Integrates Advanced Monitoring And Control With Flexible Power Ports
  • Supports Stacked Configuration To Optimize Redundancy And Load Sharing
The Rockwell ICS Triplex T8240 Power Shelf is a 19 inch x 1U chassis designed to securely house up to three Power Packs, providing robust physical protection while maintaining optimal airflow. Unlike older models such as the T8230, the T8240 features integrated Power Ports and advanced connectivity options that enhance system monitoring and diagnostics.

Each Power Pack delivers 750 W to the DC output, and the shelf supports n+1 redundancy, enabling up to 2250 W of total power. When stacking up to four T8240 shelves, the system can achieve a total output of 9000 W, providing greater scalability and load sharing capabilities compared to earlier T8235 or T8232 shelves.

The T8240 is designed for seamless integration with Power Controllers via the TC-323 interconnect cable, allowing online voltage adjustments and monitoring of up to 12 Power Packs across multiple shelves. Spare slots are protected with Power Shields, ensuring electromagnetic integrity and safe operation. This combination of high-density power, redundancy, and advanced monitoring distinguishes the T8240 from previous Triplex power shelf models.

The T8240 Rockwell ICS Triplex Power Shelf may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
The Rockwell ICS Triplex T8240 Power Shelf is a robust 19 inch x 1U chassis designed to house up to three Power Packs, providing up to 2250 W of total power or 1500 W with n+1 redundancy. Each Power Pack delivers 750 W (31.25 A at 24 Vdc) to the DC output, ensuring reliable operation for Trusted® high-integrity power systems. Unlike the earlier Rockwell ICS Triplex T8235, the T8240 integrates enhanced connectivity features including a Power Port with a 10-way cable connector and three IEC 60320 mains plugs, streamlining both installation and monitoring.

The T8240 supports stacking up to four Power Shelves within a 19 inch frame, achieving a maximum of 9000 W total power. Compared to the T8230 Power Shelf, the T8240 offers superior flexibility with Power Ports that interconnect via ribbon cables to enable current sharing across multiple shelves. This ensures balanced load distribution and maintains precise diagnostics, a critical advantage over earlier models that required manual configuration for multi-shelf systems.

Output terminals on each T8240 Power Shelf feature three M4 screw connections, allowing the use of ring-type connectors to interface with system busbars safely. The Power Port accepts a 24 V supply and offers monitoring and control via a 25-way D connector when connected to a Power Controller. Optional integration with the 1U Power Controller allows online adjustment of output voltage and monitoring of up to 12 Power Packs across 4 shelves. This functionality highlights T8240’s operational versatility compared to the T8235, which has more limited controller integration options.

The T8240 ensures that spare slots are protected using Power Shields, maintaining system integrity and shielding against electromagnetic interference. Unused slots in the 4U bracket can be fitted with blanking plates or other equipment, providing installation flexibility. Overall, the Rockwell ICS Triplex T8240 Power Shelf combines high-density power delivery, redundancy, monitoring, and modularity, making it ideal for advanced Trusted® distributed Power Systems and setting it apart from older models like T8235, T8230, and T8232.
