MEAN WELL SDR-120 power supply
In plain English
What it does
A power supply turns incoming electrical power into the voltage and form needed by connected equipment.
A simple example
In a switchgear control panel, an AC-to-DC power supply can provide DC power for relays, controller modules and indication circuits.
What the drawings help you do
Use the selected manufacturer's drawings to check the equipment's size, mounting points and cable connections. The layout helps you plan where it fits and how it can be reached for maintenance. An illustrative 3D preview does not establish product dimensions or required clearances.
- Voltage
- The electrical potential difference between two points, measured in volts.
- Rating
- A value stating the conditions for which equipment is specified.
- Schematic
- A drawing showing function and connections rather than physical appearance.

What it represents
Locate the supply with accessible incoming power and DC output terminations. Coordinate any adjacent redundancy or distribution modules as separate equipment objects.
The GA illustration is independently authored conceptual geometry, without dimensions or scale. Refer to the manufacturer STEP and selected product instructions for the actual mounting envelope.
How to read it
- The downloaded SDR-120 STEP has an internal filename identifying SDR-120-24; verify applicability before using that geometry for another voltage variant.
- A family download label does not prove every listed electrical option has an identical physical configuration.
Information to show or reference
- Record the complete output-voltage order code.
- Check the selected CAD configuration, terminal access and rail attachment.
- Apply manufacturer installation spacing and reserve cable bend and replacement space.
A distinction that matters
