Industrial DIN-rail power supply

The TRENDnet TI-S12048 is an IP30-rated industrial power supply with an integrated DIN-rail mount. It delivers up to 120 watts at 48 volts and 2.5 amps for PoE switches, cameras and access points. The unit is UL 508 approved and passes a 100 percent full load burn-in test. Condition is new.

Build integration

The compact enclosure clips onto a standard DIN rail inside a cabinet or enclosure. Active PFC with a power factor above .93 reduces harmonic distortion on the supply line. High efficiency of 91 percent lowers waste heat in the cabinet. Protection circuits guard against short circuit, overload, over voltage and over temperature.

Operating envelope

The supply operates continuously from -25 to 70 °C (-13 to 158 °F) without derating. This wide range suits unheated or uncooled industrial sites. The rugged IP30 housing resists dust ingress in harsh environments. It is designed specifically to power the TI-PG541 and similar 48 V PoE equipment.

Questions about this item

At what temperature does the TI-S12048 reach its thermal limit during continuous operation?

The unit is rated for an extreme operating range of -25 to 70 °C, so sustained load is supported up to 70 °C ambient.

How much heat and noise should I expect when the supply runs at full load all day?

High 91 % efficiency and active PFC above .93 keep waste heat low; the IP30 metal enclosure uses convection cooling with no fan, so operation is silent.

Which specific TRENDnet switch is this power supply designed to power?

The supplier title identifies the TI-S12048 as the power supply for the TI-PG541 industrial PoE switch.
