Napajalnik Trendnet TI-S12048 v1.0R

TRENDnet TI-S12048 is a 120 W single-output industrial DIN-rail power supply (Mean Well SDR-120-48) designed to deliver stable 48 V DC power for PoE equipment. It supports an AC input of 100–240 V, 50–60 Hz, features a metal enclosure with integrated DIN-rail mount and passive cooling, and includes multiple protection mechanisms for reliable operation in industrial environments.

Advantages

The TI-S12048 provides up to 120 W (48 V, 2.5 A) output power suitable for switches, network cameras and WiFi access points. Built-in active PFC (power factor > 0.93) reduces unusable reactive power. The unit includes protections against overload, short circuit, over-voltage and over-temperature, and it undergoes a 100% full-load burn-in test. The metal housing with DIN-rail mount and passive convection cooling supports vibration resistance and wide operating temperatures from -25 to 70 °C.

Suitable for

• Industrial PoE switches
• Network cameras and surveillance systems
• WiFi access points and wireless infrastructure
• DIN-rail installations in control cabinets and machinery

How to use

Mount the TI-S12048 on a standard DIN rail inside a suitable enclosure or cabinet. Connect the AC input supply (100–240 V, 50–60 Hz) to the input terminals following local electrical codes, then connect the 48 V DC output to your PoE switches, cameras or access points. Verify the LED indicator to confirm the unit is powered. Ensure wiring and connections are secure before applying full load.

Recommendations

Install the power supply in a well-ventilated location to maintain passive cooling; avoid covering ventilation paths. Use proper fusing and grounding according to regional regulations, and keep ambient temperature within the specified -25 to 70 °C range for reliable operation.
