Questions about this item

What is the maximum operating temperature for the 25148-NA power adapter?

The unit is rated for continuous operation up to 50 °C (122 °F).

How much heat does the 90 W adapter produce during all-day use?

At full 90 W load the supply draws up to 264 V AC and dissipates the difference as heat; typical efficiency keeps case temperature within the 50 °C limit.

Which DC connector does the 48 V 1.87 A output require on the powered device?

The adapter delivers 48 V DC at 1.87 A through its standard barrel jack; the mating plug must match that polarity and voltage.
