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
The native housing model is a placement reference; confirm the exact input range, output rating and mounting clearances from the current specification.
Use the linked manufacturer mechanical original for dimensions and exact revision. This illustration is independently drawn, unitless and not to scale.
How to read it
- Reserve input/output wiring approach and mounting-release access.
- The WDR-120 series model is not proof of identical mounting or geometry for adjacent product series or every output-voltage variant.
Information to show or reference
- Identify WDR-120 and the selected output-voltage variant.
- Reserve input/output wiring approach and mounting-release access.
- Check manufacturer ventilation spacing and service removal.
A distinction that matters
The WDR-120 series model is not proof of identical mounting or geometry for adjacent product series or every output-voltage variant.
