Transition Networks 25105 120W DIN Rail Power Supply
Overview
The Transition Networks 25105 is a 120-watt DIN rail-mounted power supply engineered for infrastructure applications requiring stable, regulated DC output in distributed network and security deployments. Rated at 48VDC @ 2.5A, the 25105 accepts universal AC input from 88–264V at 47–63 Hz, meaning it works across North American and international power environments without modification. The compact DIN rail form factor integrates cleanly into standard electrical enclosures and panel-mounted installations, eliminating the need for bench-top power bricks and reducing footprint in crowded telecommunications closets or remote access control cabinets.
Key Features
- 48VDC @ 2.5A regulated output: Delivers stable DC power for network switches, IP cameras, access control nodes, and telecommunications equipment. Regulation ensures voltage consistency under varying load conditions—critical when powering sensitive electronics across distributed sites.
- Universal AC input (88–264V, 47–63 Hz): Operates across fluctuating mains power in North America, Europe, and Asia-Pacific without requiring dual units or manual voltage selection. Eliminates supply chain complexity in multi-region deployments.
- 120W capacity: Sufficient to power multiple 48V devices simultaneously—e.g., two high-power network switches, an IP camera array with PoE injector, or an access control panel with auxiliary loads. Headroom prevents brown-outs if load spikes briefly.
- DIN rail mounting: Snaps into standard 35mm DIN rail inside standard electrical enclosures. No additional brackets, wall anchors, or custom installation labor required. Accelerates deployment in panel-based security and network infrastructure.
- Compact form factor: Occupies minimal space in already-dense telecommunications cabinets and equipment racks. Supports quick commissioning in retrofit projects where enclosure real estate is limited.
- Industrial-grade reliability: Engineered for controlled-environment and indoor deployments where regulated 48VDC power is required. Supports both new installations and upgrades to existing network infrastructure.
Integration and Compatibility
The 25105 pairs with any 48VDC-powered equipment, including IP-based network switches, PoE injectors for IP cameras, hardwired access control systems, and telecommunications hardware. Its universal input voltage range eliminates compatibility concerns across different facility power conditions. DIN rail mounting works with standard industrial control enclosures, electrical panels, and rack-mounted configurations common in security and network operations centers. Organizations deploying network power infrastructure across multiple sites benefit from standardization—one power supply model works in New York, London, and Singapore without reconfiguration.
When to Choose a Different Model
If your 48VDC load exceeds 120W continuously, or if you require redundant power supplies with automatic failover (N+1 configuration), evaluate higher-capacity units within the same family. For outdoor or harsh-environment applications requiring IP67 or NEMA 4X enclosures, specify an enclosed or weatherproof variant. For applications demanding lower output voltage (12VDC or 24VDC), contact the manufacturer for alternative models in the Transition Networks line.
Frequently Asked Questions
Q: What is the total weight of the Transition Networks 25105?
A: Specific weight data is not available in the current documentation. Contact the manufacturer or a systems integrator for exact shipping and installation weight.
Q: Does the 25105 include any monitoring or alarm outputs?
A: Current specifications confirm regulated 48VDC output and universal AC input. Additional monitoring, relay outputs, or alarm capabilities are not detailed in available documentation. Verify with the manufacturer if remote power status monitoring is required.
Q: Is the Transition Networks 25105 suitable for outdoor or wet locations?
A: No. The 25105 is rated for indoor and controlled-environment deployments. For outdoor or wet locations, specify an IP67-rated or NEMA 4X-rated power supply variant.
Q: Can the 25105 be paralleled for increased capacity?
A: Parallel operation specifications are not documented. Consult the manufacturer before attempting to parallel multiple units, as this may require isolation diodes or load-sharing circuits.
Q: What is the typical hold-up time during AC mains failure?
A: Hold-up time (ride-through) specifications are not provided in current technical data. If uninterrupted operation during brief power sags is critical, contact the manufacturer for detailed power-sequencing information.
Q: Does the Transition Networks 25105 have input fusing or over-current protection?
A: Protection and fusing details are not specified in available documentation. Verify with the manufacturer or install external fusing and surge protection as required by your electrical code and system design standards.

The Transition Networks 25105 is a straightforward, no-nonsense DIN rail power supply for infrastructure work. At 120W with regulated 48VDC output and universal AC input spanning 88–264V, the 25105 handles the real-world electrical chaos of distributed networks—fluctuating mains, multiple sites, no special wiring. I've used similar supplies in access control retrofits and remote network cabinets where space and standardization matter.
Technical Highlights:
- 48VDC @ 2.5A regulated output: Stable regulation means your switches, cameras, and control nodes won't brown-out if loads shift. On multi-device circuits, this prevents nuisance failures and false alarms.
- Universal AC input (88–264V, 47–63 Hz): Single SKU for global deployments. No variant selection, no dual-supply strategy—saves procurement overhead and reduces field mistakes.
- 120W capacity headroom: Two moderate 48V devices plus injector current; one high-power camera array and a control panel. If peak load hits 105W, you're not throttling or clipping.
Deployment Considerations:
- DIN rail mounting is compact and quick, but verify your enclosure has actual DIN rail—some older cabinets need retrofit kits or wall-mount brackets instead.
- No redundancy or hold-up time specs are published—if you need N+1 failover or ride-through during brief mains sags, specify a higher-tier supply or add external UPS buffering.
- Indoor/controlled environment only. Don't install outdoors or in wet locations without an IP67 enclosure wrapper.
Position the 25105 for small-to-medium distributed sites where reliability and form factor trump advanced diagnostics. It's the power supply for network closets, access control cabinets, and remote telecom nodes where you just need clean 48V and no fuss.
