Industrial 1000W 48V DC power supply
The TRENDnet TI-RSP100048 delivers up to 1000W at 48V DC with a 21A output rating. It is built for industrial equipment such as PoE switches and wireless access points. The unit fits 4U 19-inch rackmount chassis like the TI-R4U, which is sold separately. High efficiency of 94% keeps power dissipation low in continuous operation.
Check rack space and DC load requirements
Verify that your rack enclosure provides a 4U 19-inch slot and that the connected devices accept a 48V DC input. The supply includes a built-in DC OK relay contact for remote monitoring. Active power factor correction is integrated, so no external PFC stage is needed. Ensure the operating temperature range of -25°C to 70°C matches the installation environment.
Sustained load behaviour with forced-air cooling
Built-in DC fans provide forced-air cooling to maintain stable output during prolonged full-load runs. The unit has passed a 100% full-load burn-in test and carries UL 508 approval. Protections against short circuit, overload, over voltage and over temperature activate automatically under sustained stress. Efficiency remains at 94% across the load range, limiting heat buildup over time.

Domande su questo articolo
What comes in the box with the TI-RSP100048 and what must be purchased separately?
The package contains the 1000W 48V DC 21A power supply with built-in DC fans and a DC OK relay contact; the compatible 4U 19" rackmount TI-R4U enclosure is sold separately.
How do I choose between the available versions or capacities of this power supply?
The TI-RSP100048 is offered as a single 1000W 48V DC 21A model; there are no alternative wattage or voltage versions listed for this part number.
What does the 94% efficiency figure mean once the unit is installed in a real machine?
At full 1000W output the supply converts 94% of input power to usable DC, so waste heat is limited and operating temperatures stay within the -25°C to 70°C range.
