Frequently Asked Questions
What is the output of the T400V5.0A1?
The manufacturer specification lists a single +5.0V DC output, 400W power and a 0–80A current range at 100–240Vac input.
Can it operate on 110V or 230V AC?
Both voltages fall within its 90–264Vac input range. Review the PDF’s derating information for the planned load and input conditions.
What efficiency is specified?
At 100% load, the listed efficiency is greater than 88.0% at 100Vac and greater than 90.0% at 240Vac.
Is -30°C the continuous operating temperature?
No. The listing specifies -30°C startup and an operating range of -10°C to +70°C. Check the temperature derating curve before selecting a continuous load.
Where can I find the mounting and wiring information?
