Input current and cabinet installation
AC input current and DC output current are different ratings. The maximum input current in the PDF is ≤5.5 A; the 80 A figure describes the 5 V DC output. The document also lists an inrush current of ≤80 A, which must not be treated as a continuous operating current.
The narrow enclosure needs an auxiliary 400 × 400 × 3.0 mm heat-spreading plate under the conditions stated in the PDF. Check the cabinet’s internal temperature, load peaks, ventilation and mounting arrangement before using the full output rating. Use the drawing in the exact applicable revision when replacing an existing supply.

Frequently asked questions
What voltage and current does the MNS400PC5 supply?
The rated output is +5.0 V DC with a current range of 0–80 A and a listed power rating of 400 W. The specified output voltage range is 4.9–5.1 Vdc.
What is the MNS400PC5 input current?
The linked V1.0 specification lists a maximum input current of ≤5.5 A and a separate inrush-current limit of ≤80 A. Neither value is the DC output-current rating.
Does the MNS400PC5 accept 100–240 V mains?
Yes. Its rated AC input is 100–240 Vac, while the documented operating range is 90–264 Vac at 47–63 Hz. Follow the manufacturer’s operating and load requirements.
Does it need an auxiliary heat-spreading plate?
Yes. The V1.0 environmental specification calls for a 400 × 400 × 3.0 mm plate beneath this narrow supply and lists a −30 to +50°C operating range under the stated conditions.
Where can I download the MNS400PC5 specification?
The original PDF link above contains electrical ratings, derating guidance, mechanical drawings and connector definitions for the documented revision.
