Mean Well RD-65B 68W Dual Output Power Supply

SKU CH-806X-597Z9

Enclosed 68 W dual-output AT supply delivers 5 V at 4 A and 24 V at 2 A, rated for 70 °C operation with 105 °C capacitors and 300 VAC surge tolerance

  • TypeAT
  • Dual 5 V and 24 V rails power mixed-voltage systems
  • 68 W total output handles demanding industrial loads
  • 105 °C electrolytic capacitors extend operating life
  • Withstands 300 VAC surge input for 5 seconds
  • Operates reliably up to 70 °C ambient temperature

Enclosed 68 W dual-output supply

The Mean Well RD-65B is an enclosed AC-DC switching unit that delivers 68 W across two fixed rails: 5 V at 4 A and 24 V at 2 A. It is built for industrial equipment, test rigs and automation cabinets that need a compact, rugged power source with no external wiring harness.

Replaces open-frame or single-rail units

The dual-output design removes the need for a separate 5 V auxiliary supply when a 24 V main rail is already required. The jump is worth it when an existing open-frame module cannot meet vibration or temperature specs, or when a single-rail brick forces extra DC-DC converters into the cabinet.

Sustained operation at 70 °C ambient

The supply is rated for continuous duty at 70 °C using 105 °C electrolytic capacitors and survives 300 VAC input surges for 5 seconds. It withstands 5 G vibration without derating, so output remains stable during prolonged heavy-load cycles in harsh environments.

Questions about this item

What mounting holes or bracket does the 68 W enclosed supply use?

The unit is an enclosed AT-type supply with standard chassis-mount holes; secure it to the case with four screws through the corner flanges.

How do I wire the dual outputs and which step is often missed?

Connect AC input to L, N and ground, then attach CH1 5 V at 4 A and CH2 24 V at 2 A; the step most installers forget is tightening the ground lug before powering on.

Which component should I plan to replace after long 70 °C operation?

The 105 °C-rated electrolytic capacitors are the wear items; expect to recap the supply after several years of continuous high-temperature use.
