️· Manufacturer: (Not explicitly stated, but presumed to be a manufacturer specializing in power supplies)
️· Document Revision: 26-Sept-13 (implies there have been previous revisions)

2. Models / Configurations

️· The SDC320 is available in several configurations, differing mainly in their enclosure/mounting style:
- U-Channel: Basic mounting style.
- U-Channel with Cover (C Option): Enclosed U-Channel with a cover.
- Enclosed with End Fan (E Option): Enclosed design with an end-mounted fan.
- Enclosed with Top Fan: (Not described in detail in the provided text, but implied by the various options).
️· Optional Features:
- Option 'D': Indicates a connector option (JST connector with specific housing and crimp terminals – see Mechanical Details below)

3. Electrical Specifications (General - No specific numbers provided)

️· Output: (Details depend on the specific SDC320 version – no specific voltage/current ratings are listed. It is assumed to be a configurable power supply)
️· Power Good (PG):
- Output ON: >0.3V or open circuit
- Output OFF: <0.3V or short circuit
️· Fan Fail (FF):
- Fan OK: Open circuit
- Fan Failed: Short circuit
️· Remote On/Off (SDC320P models only):
- Output ON: >4.5V or open circuit.
- Output OFF: <0.3V or short circuit. The signal can pull up to 5-28VDC and has a maximum sink current of 5mA.

Important Notes/Limitations

️· Missing Electrical Specs: The *most crucial* information – the voltage, current, and power output ratings – are NOT specified in this document. This is a catalog sheet or a technical overview, not a detailed specification sheet.
️· Model Specifics: Many details are model-dependent. You need to refer to the diagrams and descriptions of the specific SDC320 version you are using.
️· SDC320A vs SDC320P: The document mentions SDC320A and SDC320P models, with some differences in connector types.
