Industrial Table-Top Power Supply

This MEAN WELL unit delivers 252 W at 12 V with a 21 A continuous rating for desktop server chassis builds. The 3-wire AC input and Molex 39-01-2060 output connector suit industrial and embedded deployments. It meets Level VI efficiency requirements for low standby draw. The supply ships new in a compact 8.66" × 3.74" × 1.81" enclosure weighing 3.28 lbs.

Thermals Noise and Power Draw

Passive convection cooling keeps the unit silent in normal operation with no fan noise to manage. The Level VI rating confirms low no-load and average active efficiency across the input range. Rated output power is 252 W at 12 V 21 A without derating in the specified temperature window. The 4.2 mm pitch connector handles the full current path with minimal voltage drop.

Build Quality and Connectors

The Molex 39-01-2060 connector uses a 4.2 mm pitch and six pins for secure DC delivery to the chassis backplane. Desktop form factor allows bench or rack-shelf mounting without dedicated rails. 3-wire AC inlet supports grounded mains cords for industrial safety compliance. Buyers needing on-board ATX connectors or modular cabling should select a different supply.

Questions about this item

How do I connect the Molex 39-01-2060 4.2mm connector to my server chassis?

Align the 4.2 mm pitch Molex 39-01-2060 plug with the chassis power inlet and press firmly until the latch clicks. The step most people miss is verifying the 12 V polarity on the 3-wire AC input before applying mains power.

Will the internal fan need cleaning or replacement during the life of this 252 W supply?

The unit uses convection cooling with no internal fan, so there is no fan to clean or replace. Keep the 8.66 x 3.74 x 1.81 in vents clear of dust to maintain airflow.

At what load does the 12 V 21 A output hit its limit during continuous operation?

The continuous limit is 252 W at 12 V, which equals 21 A. Sustained loads above this will trigger the over-current protection and shut the supply down.
