IEC plugs are a group of standardized power connectors used for 230V electrical equipment . They are commonly used in LED lighting, computers, audiovisual equipment, and industrial applications .
1. IEC C7 (also called 'Figure-8' or 'Euro 8')
🔹 Features:
- Two-pole ungrounded connector.
- Works on 230V (max. 2.5A / ~575W ).
- Widely used in lightweight LED lighting, adapters and consumer electronics .
🔹 Applications:
- LED light panels with adapters .
- Smart LED lighting such as Philips Hue lamps.
- Audiovisual equipment such as TVs and soundbars.
🔹 Compatibility:
- Connects to a C8 socket on the device.
- Fits universal power cords for light appliances.
2. IEC C13 ('Cold plug')
🔹 Features:
- Three-prong, grounded plug .
- Works on 230V (max. 10A / ~2300W ).
- Widely used in LED drivers, servers, PCs and monitors .
🔹 Applications:
- LED industrial lighting with separate power supplies.
- LED panels in offices (with separate C13 connection).
- Servers and IT equipment (requiring a stable power supply).
🔹 Compatibility:
- Connects to a C14 input on the device.
- Widely used in professional LED installations and AV equipment.
3. IEC C19 ('Heavy Appliance Plug')
🔹 Features:
- Three-pin, heavy-duty, grounded plug .
- Works on 230V (max. 16A / ~3680W ).
- Mainly used for industrial LED lighting and heavy duty servers .
🔹 Applications:
- Large LED lighting installations in companies or factories .
- UPS systems (emergency power for LED lighting and IT equipment).
- Data centers and heavy electrical equipment .
🔹 Compatibility:
- Connects to a C20 input on the device.
- Not suitable for standard household LED lighting.
Overview of differences between IEC C7, C13 and C19
| Plug | Grounding | Max. power | Applications |
|---|---|---|---|
| IEC C7 | ❌ None | 2.5A (~575W) | Lightweight LED lights, adapters |
| IEC C13 | ✅ Yes | 10A (~2300W) | LED drivers, offices, IT equipment |
| IEC C19 | ✅ Yes | 16A (~3680W) | Industrial LED lighting, heavy servers |
Which IEC plug is suitable for LED lighting?
✔ For household LED lamps → C7 (Figure-8)
✔ For office LED panels → C13 (cold plug)
✔ For industrial LED systems → C19 (Heavy equipment plug)
