1606-XLE480ERL New Original Power Module 1606XLE480ERL
PRODUCT DETAILS
1606-XLE480ERL — 480W DIN Rail Power Supply for Redundant Systems, 24V DC / 20A
The 1606-XLE480ERL is a 480W, 20A 24V DC power supply purpose-built for redundant power architectures — 1+1 or N+1 configurations where multiple supplies share a common output bus and any single unit can fail without interrupting power to connected loads. It integrates a decoupling MOSFET internally, removing the need for a separate redundancy module that standard power supplies would require for this kind of parallel operation.

Designed Specifically for Redundant Operation
Standard power supplies wired in parallel for redundancy need an external decoupling diode or MOSFET module between each unit and the shared output bus — otherwise a failed supply can backfeed or drag down the others on the same rail. The 1606-XLE480ERL builds that decoupling function directly into the unit, simplifying the panel design for redundant 24V distribution: multiple ERL units connect straight to the same output bus via their hot-swap connectors, with each one's internal circuitry handling the isolation that a separate redundancy module would otherwise provide.
If one unit fails or develops an internal fault, the redundant circuit limits its output and the unit shuts down after a defined number of restart attempts — the remaining units on the bus continue supplying the load uninterrupted. The hot-swap connector design means a failed unit can be replaced while the system stays powered from the surviving units, without de-energizing the whole panel.
FAQ
Q: Does this supply require a separate redundancy module to work in a redundant configuration?
No. The decoupling function is built into the unit itself — multiple 1606-XLE480ERL units can be connected to a shared output bus directly, without an additional external redundancy module.
Q: Can a failed unit be replaced without shutting down the system?
Yes. The hot-swap connectors are designed to allow removing and replacing a faulted unit while the remaining units on the same bus continue supplying power to the load.
Q: How many of these units can be connected together on one bus?
The architecture supports both 1+1 (one active, one standby/sharing) and N+1 (multiple units sharing load with one spare) configurations — the specific number depends on the total load current required and the desired redundancy margin.
Q: Is the output voltage adjustable on this model?
No. The output is fixed at 24V DC nominal on this redundancy-oriented model, unlike some standard XLE units that offer an adjustable output range.
