Overview
About the Lantronix 25105 DIN-Rail Power Supply
Hardened PoE switches and media converters usually run from a DC input, not mains power, so a cabinet installation needs a DIN-rail supply alongside them. The Lantronix 25105 (part number 25105) fills that role. It accepts 88-264 VAC or 124-370 VDC and outputs 48-55 VDC at 2.5 A, for 120 W of continuous power, from a module that clips onto the same DIN rail as the equipment it feeds.
Lantronix lists 94% efficiency and 150% peak load capability, which helps when powered devices draw inrush current at start-up. The supply is protected against short circuit, overload, over-voltage and overheating, uses fanless convection cooling, and is UL 508 approved. Each unit goes through a full-load burn-in test and is RoHS compliant. On the 25105 product page, Lantronix lists the SI-IES-511D-LRT and SI-IES-521D-LRT hardened PoE++ injector/converters as matching products. Before installing, confirm that the connected equipment's input range overlaps the 48-55 VDC output and that its full-load draw stays within 120 W.
Key capabilities
- Universal AC or DC input
- Accepts 88-264 VAC or 124-370 VDC, so the same supply works from mains power or a high-voltage DC source in the cabinet.
- 120 W at 48-55 VDC
- Delivers 2.5 A at 48-55 VDC, the 48 VDC class of input used by hardened PoE switches and PoE++ media converters.
- 150% peak load
- Handles short peaks up to 150% of rated load, giving headroom for powered-device start-up surges.
- Fully protected
- Protection against short circuit, overload, over-voltage and overheating, with fanless convection cooling and UL 508 approval.
How to choose the right 25105 DIN-Rail Power Supply part number
There is a single part number, 25105: one DIN-rail supply rated 48-55 VDC at 2.5 A (120 W). Check the total load before choosing it. A 120 W output suits a single SI-IES-511D-LRT, whose PoE budget is 90 W, while the two-port SI-IES-521D-LRT, with a 180 W budget and 220 W full-load draw, needs a higher-rated supply when both ports run at full power. Lantronix lists other supplies, such as the 240 W 25104, on its hardened switch pages.
