1606-XLE120E | Allen-Bradley Switched Mode Essential Power Supply

Product Overview

The Allen-Bradley 1763-L16BBB serves as a high-efficiency power conversion solution within the 1606 Switched Mode Power Supply line. It converts wide-range AC or DC input voltages into a stable 24V DC output to drive PLC racks, HMI terminals, and field sensors. This "Essential" series module balances a compact physical footprint with industrial-grade thermal management. We supply this unit as 100% brand new and original in factory packaging to ensure peak electrical performance and longevity.

Engineering Advantages

• Superior Thermal Efficiency: The 94.3% efficiency rating minimizes heat dissipation within the control cabinet. By losing only 7.3 Watts as waste heat, this unit reduces the cooling requirements for the entire enclosure, preventing the premature aging of adjacent electronic components.

• Dynamic Power Buffering: This power supply provides a 20% power reserve. This extra headroom handles the high inrush currents often generated when starting inductive loads or large DC motors, preventing system-wide voltage drops or nuisance tripping.

• Flexible Input Compatibility: The unit accepts both wide-range AC and specific DC inputs. This dual-input capability allows engineers to standardize on one part number for global deployments or for use in DC-battery backed emergency systems.

• Extended Cold-Start Reliability: The wide operating temperature range (-25°C to 70°C) ensures stable startup in unheated outdoor cabinets. The ruggedized internal components maintain a high power factor even at the upper limits of the temperature curve.

• Vibration-Resistant Terminations: The screw/spring terminal design ensures gas-tight electrical connections. This technology maintains circuit integrity in high-vibration environments, such as those found in mining, milling, or heavy manufacturing applications.

FAQs

• Can I adjust the output voltage above 24V?

  Yes. The front-mounted potentiometer allows you to adjust the output between 24V and 28V DC. This feature compensates for voltage drops across long cable runs to remote field devices.

• Does this power supply support parallel operation for redundancy?

  The 1606-XLE120E works in parallel configurations when used with an external redundancy module. This setup ensures that if one power supply fails, the secondary unit continues to power the critical load without interruption.

• What is the benefit of the 0.91 power factor?

  A high power factor indicates that the unit draws current more efficiently from the AC grid. This reduces the reactive power load on your facility’s electrical infrastructure and may help lower energy costs in large-scale deployments.

• Is this unit compatible with DC input sources?

  Yes. The unit supports a DC input range of 110–150V DC, making it suitable for specialized industrial networks or renewable energy integration.
