Description

The Allen-Bradley 1746-P6 is a specialized power supply module for the SLC 500 series, engineered to operate on a 48V DC nominal input. This module is specifically designed for applications in telecommunications, solar power arrays, or industrial facilities that rely on 48V DC battery banks. It provides regulated DC backplane power to the SLC processor and associated I/O modules, ensuring stable system operation in isolated power environments.

Features

  • Designed for 48V DC nominal input (30-60V DC range).
  • Provides 5.0 Amps at 5V DC for logic circuitry.
  • Provides 0.96 Amps at 24V DC for backplane relay coils.
  • Includes a dedicated 24V DC User Power output (200 mA) for external field devices.
  • Robust 1800V AC RMS isolation between input terminals and the backplane.
  • High-efficiency design with integrated CPU hold-up capabilities.

Applications

The 1746-P6 is ideal for remote industrial sites where AC power is unavailable or unreliable, allowing the SLC 500 system to be powered directly from DC battery systems. It is commonly used in telecommunications infrastructure, renewable energy monitoring, and mobile or off-grid control systems.

Installation Guidelines

  • Ensure the system power is disconnected before installing or removing the power supply from the SLC 500 chassis.
  • The 1746-P6 must be installed in the leftmost slot of the chassis.
  • Ensure proper grounding of the chassis to minimize electrical noise and protect against surges.
  • Maintain adequate clearance around the module for proper ventilation and cooling.
  • Use appropriate wire gauges for the DC input terminals to minimize voltage drop.
  • Handle with care to avoid electrostatic discharge (ESD) damage to internal components.

FAQ

Is the 1746-P6 compatible with all SLC 500 chassis?

Yes, the 1746-P6 is designed to fit into the standard SLC 500 modular chassis series. It is always installed in the leftmost slot designated for the power supply.

Can I use this power supply with an AC input?

No, the 1746-P6 is specifically designed for DC input (30-60V DC). Connecting it to an AC power source will damage the unit.
