Bloc d'alimentation Trendnet TI-S24048 v1.0R

TRENDnet TI-S24048 (Mean Well SDR-240-48) is a 240 W single-output industrial DIN-rail power supply that provides 48 V at up to 5 A for PoE equipment. Housed in a metal enclosure with an integrated DIN-rail mount, the unit supports AC input of 100–240 V, 50–60 Hz and is certified by UL and TUV. It is designed for industrial environments with vibration resistance and an operating temperature range from -25 to 70 °C.

Advantages

This power supply delivers stable 240 Watts of output power suitable for powering PoE switches, network cameras, and wireless access points. An integrated active Power Factor Correction (PFC, PF > 0.93) reduces unusable reactive power. The unit includes comprehensive protection against overload, short circuit, over-voltage and over-temperature, and it undergoes a 100% full-load burn-in test. Passive cooling by free-air convection minimizes moving parts, and an LED indicator provides a clear visual confirmation of power.

Suitable for

• Industrial PoE switches
• Network/IP cameras
• Wireless access points and Wi‑Fi equipment
• DIN-rail mounted network installations and control cabinets

How to use

Install the TI-S24048 onto a compatible DIN-rail inside the electrical or network cabinet and secure the unit according to standard DIN-rail mounting procedures. Connect the AC input to a suitable 100–240 V AC supply with correct grounding. Connect the 48 V DC output to the PoE switch or other 48 V devices, observing polarity and load limits. Verify the LED indicator to confirm the unit is powered. Ensure wiring and connections comply with local electrical codes and the equipment manufacturer’s recommendations.

Recommendations

For reliable long-term operation, ensure adequate ventilation around the unit to allow free-air convection cooling, avoid placing the supply near strong heat sources, and verify that the total connected load does not exceed the 240 W (48 V, 5 A) rating. Use appropriate circuit protection on the AC input and follow grounding best practices.
