Mean Well

Mean Well NET-35B 33W Triple Output Power Supply

SKU CH-VFNK-FPPBY

Enclosed 33 W AC-DC supply delivers 5 V at 3 A, 12 V at 1 A and -12 V at 0.5 A

  • TypeAT
  • Delivers 33 W total power across three regulated outputs
  • Triple-output design provides 5 V, 12 V and -12 V rails
  • Channel one supplies up to 3 A at 5 V
  • Channel two supplies up to 1 A at 12 V
  • Channel three supplies up to .5 A at -12 V

Triple Output Power Supply

The Mean Well NET-35B is an enclosed 33 W AC-DC switching unit delivering three regulated rails. Channel one provides 5 V at 3 A, channel two supplies 12 V at 1 A and channel three outputs -12 V at .5 A. It fits low-power systems that need both positive and negative voltages from a single compact module.

Ideal for Simple Analogue and Logic Circuits

Engineers building test fixtures, industrial controllers or retro-computing projects will appreciate the triple-rail layout in one housing. Builders who require higher current on the 12 V line or additional output voltages should look at larger units instead.

33 W Total Power Rating

The combined output is rated at 33 W across all three channels. This figure determines whether the supply can handle the intended load without overheating or shutting down.

Questions about this item

How do I mount the NET-35B and which step is commonly missed?

Mount the enclosed unit on a flat metal surface using the four corner holes; the step often missed is leaving enough clearance for convection airflow around the case.

What maintenance or replacement will the NET-35B need over time?

The internal electrolytic capacitors age with heat; plan to replace the supply after several years of continuous operation when output ripple rises.

Which limit appears first when the NET-35B runs at full load for long periods?

The 33 W total power ceiling is reached before any single rail hits its current rating, so sustained loads above that level will trigger protection.
