1746-P2 - Power Supply Module - ALLEN BRADLEY
This 1746-P2 and ALLEN BRADLEY brand power supply module is part of the SLC 500 range.
Line Voltage: 85-132 VAC / 170-265 VAC, 50/60 Hz. Fuse replacement 250V / 3A.
This 1746-P2 power supply module is at your disposal to replace your defective equipment and has a guarantee adapted to your needs.
SLC 500 controllers continue to operate for a short time if the input voltage of the power supply drops below the recommended operating voltage range. The controller continues to scan the user program and control the I / O during this time. Maintaining the processor for each power supply is shown on pages 14 and 16.
The SLC 500 controllers will turn off (stop scanning and disable outputs) if the power input voltage is cut off or falls below the recommended operating range for a period of time beyond the processor hold time. The controller resumes operation automatically when the input voltage returns to normal.
If the input voltage of the 1746-P7 power supply falls within a range of 4 to 9V for a period exceeding the CPU hold time, the controller turns off and on again as long as the input voltage is not increased to 11Vdc.
When configuring a modular system, you must have a powersupply for each chassis.
Careful system configuration will result in optimal system performance. Excessive loading of the power supply outputs can cause a power supply shutdown or premature failure.
The SLC system features three AC power supplies and four DC power supplies.
The power supply mounts on the left side of the chassis with two screws. For AC power supplies, 120/240 volt selection is made by placing the jumper to match the input voltage. SLC power supplies have an LED that illuminates when the power supply is functioning properly.
Power supplies are designed to withstand brief power losses. Power loss does not affect system operation for a period between 20 ms and 3 s, depending on the load.
