1606-XL480E

The Allen-Bradley/Rockwell Automation 1606-XL480E power supply module is manufactured as part of the Allen-Bradley Bulletin 1606-XL Switched Mode Power Supply product line. It operates on an input voltage of 230 Volts with a frequency between 47 and 63 Hertz. This power supply has a continuous operation tolerance voltage range of 184 to 264 Volts AC or 270 to 370 Volts DC and a short-term (1 minute) voltage tolerance of 170 to 280 Volts AC or 250 to 400 Volts DC at 24 Volts and 20 Amps of current. The Allen-Bradley 1606-XL480E power supply has an input current of 5 Amps and a typical inrush current of 33 Amps at 264 Volts AC. This unit has an output voltage range 24 to 28 Volts and that can be adjusted by using a front panel potentiometer, a preset voltage of 24 Volts with a guaranteed adjustment range of ± 0.5 percent.

The Allen-Bradley 1606-XL480E switched mode power supply unit exclusively operates on long-life electrolytics that are specified for 105 degrees Celsius. It also has a high level reliability since only four aluminum electrolytics are used and they do not need small aluminum electrolytics. If the operators wish to protect the primary side of the power supply by using a circuit breaker or fuse, then installing a 10 Amps slow-acting fuse or an extra protector module like the 1492- SPU1C100 module is recommended. Always consult the local codes and regulations to ensure proper installation. The 1606-XL480E power supply supports the parallel operation of up to ten units. The output V/I characteristic can be changed to a softer of 25 Volts at 0.4 Amps or 24 Volts at 20 Amps to achieve current sharing. This can be done by moving the bridge connection without opening the unit.
