Main Features and Advantages
Ultra-Slim 32 mm Housing Frees Cabinet Space:
The defining physical characteristic of the 1606-XLE80E is its compact 32 mm width, which at 80 W output places it among the narrowest industrial power supplies available in this output class. In densely packed control cabinets — where every millimetre of DIN rail competes with I/O modules, safety relays, interposing relays, and network switches — the slim profile of the 1606-XLE80E directly translates into more usable mounting space per panel, smaller enclosure sizes, and lower overall cabinet cost. The housing accepts both DIN-rail and wall mounting, giving panel builders flexibility on non-rail installations such as backplate-mounted retrofits or OEM machine packages.
Wide AC and DC Input Range Without Model Changes:
Input auto-selection on the Allen-Bradley 1606-XLE80E accepts AC 100-240 V at 50/60 Hz alongside a DC 110-300 V supply, meaning the same catalogue number can serve global OEM machine builds and dual-voltage installations alike. Plants that run portions of their control system from a rectified DC bus — common in substations, oil-and-gas switchgear, and marine power systems — can deploy the identical part number as on conventional AC-fed panels, simplifying spares holding and eliminating confusion during maintenance interventions. The NTC-based inrush limiter holds starting current to 23 A / 45 A, protecting upstream breakers and ensuring trouble-free parallel operation of multiple units on a shared feeder.
Dynamic 120 % Power Boost and Stabilised Output:
Beyond its 3.3 A continuous rating, the 1606-XLE80E delivers a 120 % dynamic power reserve whenever the ambient temperature is below 45 °C — a capability that absorbs short-duration inrush peaks from solenoids, contactor coils, DC-DC converters, and lamp loads without nuisance tripping or output collapse. Output voltage is fully stabilised and adjustable between 24 V and 28 V DC, allowing the installer to compensate for cable voltage drop on long field runs or to bias the bus slightly high for downstream 24 V loads with tight minimum-voltage requirements. Ripple and noise are held to a maximum of 50 mV, keeping analogue-input cards and precision sensors free from supply-induced noise.
DC OK Relay Contact for Immediate Health Monitoring:
A built-in DC OK relay contact on the 1606-XLE80E provides an isolated dry contact that drops out whenever the 24 V DC output falls below its healthy threshold, giving the host PLC, watchdog circuit, or supervisory DCS an immediate signal of power-supply distress. This simple yet powerful feature allows faults to be alarmed at the control-room level rather than being discovered only when a field device stops responding, supporting the predictive-maintenance practices that modern manufacturing operations demand.
NEC Class 2 Listing Simplifies Design and Compliance:
Because the is UL-listed as an NEC Class 2 Limited Power source, downstream circuits fed by the supply are exempt from many of the enclosure, segregation, and overcurrent-protection requirements that apply to Class 1 circuits under the U.S. National Electrical Code. For machine builders exporting to North America, this classification reduces wiring cost, simplifies inspection, and shortens the certification pathway for the overall control system — a meaningful commercial advantage alongside the purely technical benefits.
