Allen-Bradley 1606-XLS960E-3 Performance Power Supply

Configured for high-density DC power conversion in industrial control systems, the Allen-Bradley 1606-XLS960E-3 (1606-XLS960E-3 Power Supply) provides direct physical execution of AC-to-DC voltage rectification and regulation across three-phase power platforms.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks

The 1606-XLS960E-3 maintains voltage stability within automated systems that utilize backplane-mounted controllers. While the power supply itself provides raw DC bus potential, its output characteristics ensure that deterministic networks, such as those utilizing EtherNet/IP or Profinet, remain unaffected by voltage dips or transient noise. The module supports I/O density scaling by providing a stable 24 VDC source for high-load segments of the I/O rack. Proper firmware flash compatibility of connected control modules is dependent on the stable input voltage provided by this power supply, ensuring that communication modules maintain consistent bus communication velocity during peak power demand periods.

Frequently Asked Questions

Q: Can this power supply be paralleled with another unit to increase output capacity?

A: Yes, the 1606-XLS960E-3 series supports parallel operation for load sharing. However, output voltage must be matched across all units, and cabling must be of equal length and impedance to ensure balanced current distribution.

Q: Is a neutral connection required for the 380-480 VAC input?

A: This model is designed for three-phase operation. Refer to the specific terminal block labeling to verify if the installation environment requires a 3-wire or 4-wire connection based on the facility grid topology.

Field Installation Guidelines

1. Mount the power supply on a standard DIN rail within an enclosure, ensuring adequate clearance on all sides to facilitate natural convection cooling.
2. Terminate the 380-480 VAC input lines to the designated input terminals, ensuring proper phase rotation for 3-phase operation.
3. Use high-conductivity copper conductors sized appropriately for the load current to minimize voltage drop over distance.
4. Verify that the PE (Protective Earth) terminal is securely bonded to the main cabinet ground stud to ensure internal EMI filter effectiveness.
5. Inspect the output voltage setpoint to ensure it is adjusted within the 24-28 VDC range as required by the connected controller or I/O modules.
