Description

The Honeywell 51196653-100 is a chassis-mounted TDC 3000 Five-slot File Power Supply engineered to provide stable operating power for Local Control Network (LCN) node chassis files within TotalPlant Solution (TPS) and TDC 3000 control architectures. Rated for 55 A output capacity, this power supply module energizes node processor boards, coprocessors, drive trays, and peripheral I/O modules across the backplane file assembly.

Designed for high system availability, the 51196653-100 features built-in voltage margining controlled by an accessible front jumper. This capability allows system engineers to adjust output voltage margins by +5% during diagnostic tests and factory troubleshooting. The module integrates a front-panel power switch, reset control, and dedicated status indicators to provide immediate local feedback on supply integrity.

Built to meet European EMC and Health and Safety Directives, the CE-compliant Honeywell 51196653-100 incorporates standard 3-pin AC connector interface standards and high-efficiency fan cooling to ensure reliable thermal management in continuous industrial automation environments.

Features

• High-Capacity Current Delivery: Delivers up to 55 A of regulated power across the backplane to support multi-slot LCN node assemblies, processors, and disk trays.
• Voltage Margining Test Capabilities: Equipped with a front-accessible jumper allowing +5% high-margin voltage adjustment for maintenance testing and troubleshooting routines.
• Integrated Front-Panel Diagnostics: Includes a dedicated Power OK status LED, power switch, and manual reset button for real-time visual monitoring and control.
• CE-Compliant Safety Architecture: Fully compliant with European Union EMC and Health and Safety Directives for industrial control enclosures.
• Standard Industrial AC Input: Features a standard 3-pin AC connector for simple, secure power entry connections.
• Forced-Air Thermal Management: Built-in fan assembly provides continuous internal cooling to maintain optimal operating temperatures within 5-slot file chassis.

Applications

• TDC 3000 & TPS LCN Nodes: Main power conversion module for 5-slot file chassis housing Application ModuleX (AXM) processors, K2LCN, or K4LCN node boards.
• Industrial Control File Enclosures: Provides clean DC power distribution across shared backplanes for memory modules, coprocessor boards, and hard disk drive trays.
• Process Automation Maintenance & Retrofits: Replacement chassis power supply module for legacy DCS infrastructure during system upgrades and maintenance overhauls.

Technical Specifications

Installation Guidelines

1. Safety Pre-Check: Disconnect primary AC source power before inserting or removing the power supply from the file chassis. Ensure proper ESD protective grounding procedures are observed.
2. Jumper Verification: Verify that the front voltage margin jumper is locked in the Normal ("Norm") position prior to powering on process-active equipment.
3. Chassis Alignment: Slide the power supply module smoothly into the left-hand power slot of the 5-slot file chassis until backplane connectors seat firmly.
4. AC Power Connection: Connect the primary power line using the standard 3-pin connector interface.
5. System Startup: Apply power using the front-panel toggle switch. Verify that the green "Power OK" LED turns on and fan airflow is active.

Replacement Recommendations

• Software Shutdown Prior to Power-Off: Always perform an orderly software shutdown of node processor software and coprocessor operating systems (such as HP-UX on AXM nodes) prior to switching off or removing the power supply. Removing power unannounced can result in corrupted file systems on hard disk drive trays.
• Voltage Margining Restrictions: The low power margin option (-5%) must NEVER be selected on chassis containing AXM nodes or hard drive trays, as their hardware design requires a tight power supply tolerance (maximum -2.5% drop). Operating on low margin will cause unpredictable system behavior or disk faults.
• On-Process Restrictions: Do not execute high (+5%) or low (-5%) margin tests while the node is actively controlling or participating in an online process.
