SEALTEL POWER UNIT 2311390146 0C07 1619

1. Product Type: Power Unit (Power Supply Unit)

This is a component that converts AC (alternating current) mains power to the regulated DC (direct current) voltages required by sensitive electronic equipment. It provides stable, clean power and often includes battery backup functionality.

2. Brand/Manufacturer: SealTel

• SealTel is commonly associated with Seal Telecom, an Indian company that designs and manufactures telecom infrastructure solutions, including for the railways.
• This part is almost certainly for a Railway Telecom or Railway Signaling system, or for other ruggedized outdoor telecom cabinets (like for FTTH, mobile base stations, etc.).
• SealTel/Seal Telecom products are known for being rugged, reliable, and designed to operate in harsh environments with wide temperature ranges and unstable grid power.

3. Key Features :

• Hot-Swappable: Most such units in telecom racks are hot-swappable, allowing replacement without shutting down the entire system.
• Redundant Configuration: They are typically used in parallel (N+1 redundancy) to ensure continuous power.
• Wide Input Voltage Range: Can handle a broad range of AC input (e.g., 90V – 300V AC) to cope with voltage fluctuations common in industrial and remote sites.
• Multiple DC Outputs: Provides standard telecom voltages like +24V DC, -48V DC, or +12V DC. The “0C07” in the code might indicate a specific output voltage/current configuration.
• Battery Management: Includes charging circuits for external backup battery banks (like lead-acid or Li-ion) with float/boost charging and protection.
• Monitoring and Alarms: Features digital displays, LEDs, and relay contacts for remote monitoring of input/output voltage, load current, and fault status (AC fail, DC low, battery fault).
• Robust Enclosure: Metal casing for EMI shielding and durability, designed for 19-inch rack mounting.

4. Part Number Analysis:

• 2311390146: This is likely the core part or serial number.
• 0C07: Possibly a hardware revision code, configuration code, or output specification identifier.
• 1619: Could indicate a manufacturing date (16th week of 2019) or another revision.

5. Typical Applications:

• Railway Communication Systems: Powering routers, radios, and control systems in railway stations and along tracks.
• Optical Line Terminal (OLT) Cabinets: For fiber-to-the-home (FTTH) networks.
• Mobile Base Station (BTS) Shelters: Powering radio equipment and backhaul.
• Traffic Signal Control Systems: Where reliable power is critical.
• Industrial IoT and SCADA Systems.

Key Features & Benefits:

• High Reliability & Redundancy: Designed for N+1 parallel operation to guarantee zero downtime for essential communication systems.
• Wide Input Range: Automatically adjusts to AC input voltages from 90V to 300V, perfect for areas with unstable power grids.
• Comprehensive Battery Management: Integrated smart charger for external backup batteries, ensuring seamless transition during power outages.
• Full System Monitoring: Visual LEDs and remote alarm contacts for real-time status on AC/DC power, load, and battery health.
• Rugged & Compact Design: Built for 19″ telecom racks with a robust metal housing that protects against EMI and environmental stress.
• Hot-Swappable Design: Allows for easy maintenance and replacement without powering down your entire network.
