Confirm the supplied unit’s terminal rating and physical fit before installation; the total output rating is not a per-terminal rating.
Frequently Asked Questions
Is the YY-D-300-5 suitable for a 220V AC supply?
220VAC falls within the documented 200–240VAC nominal input range. Confirm the supplied unit’s nameplate before connection.
How much DC output does it provide?
The linked model specification rates the output at 5V DC, 60A and 300W.
Is this a fan-cooled power supply?
Yes. The product description specifies fan cooling with speed adjusted according to power-supply temperature.
What size is the YY-D-300-5?
The listing gives 212 × 85 × 30mm, while the PDF gives 215 × 87 × 30mm. Confirm the actual enclosure and mounting holes rather than assuming either size fits.
