The TRENDnet TI-S12048 is a high-efficiency AC-to-DC industrial DIN-rail power supply with built-in Active Power Factor Correction (PFC) designed to optimize performance for mission-critical network deployments. Engineered specifically for high-draw environments, the upgraded V2 architecture supplies up to 150W of continuous power (48V–56V DC, 3.12A) to high-power industrial Power over Ethernet (PoE) equipment, including managed switches, multi-gigabit injectors, and heavy-duty outdoor PTZ surveillance cameras.
Enclosed in a rugged, IP30-rated metal housing with an integrated TS-35 DIN-rail mounting clip, the TI-S12048 is designed for rapid installation inside standard automation panels and traffic enclosure cabinets. It features a fanless, passive cooling design and an intelligent multi-layered safety matrix that includes automated recovery from short circuits, overloads, and extreme thermal spikes, ensuring flawless 24/7 infrastructure stability.
Key Features
- Upgraded 150W High Output: Delivers clean, continuous power (48V to 56V adjustable output range, 3.12A) optimized perfectly for high-budget PoE+ and PoE++ applications.
- Active Power Factor Correction (PFC): Integrated active controller increases power supply efficiency and eliminates reactive power loss to stabilize line currents.
- Harsh Weather Endurance: Engineered with silent, fanless natural convection cooling to operate seamlessly under extreme temperatures ranging from -25° to 70°C (-13° to 158°F).
- 150% Peak Load Headroom: Advanced power engineering handles startup inrush currents and dynamic peak demands safely without tripping systems.
- Smart DC OK Diagnostic Relay: Features built-in hardware relay dry contacts to continuously report hardware line health and instantly signal backend alert infrastructure if power drops.
- Advanced Failure Protection: Comprehensive self-recovery protection systems safeguard your network against unexpected short circuits, overloads, over-voltage spikes, and over-temperature occurrences.
