Global Standardization
The International Electrotechnical Commission (IEC) ensures universal interoperability. Servers manufactured globally utilize the same C14 or C20 inlets, allowing operators to deploy infrastructure without regional power port constraints or the need for internal power supply modifications.
Optimized Density & Voltage
IEC connectors offer a compact footprint, allowing PDUs to maximize outlet density per rack. Rated for up to 250V, they support 208V/230V architectures that reduce current ($I$) for the same power ($P$), significantly minimizing heat loss and increasing efficiency.
Specialized Connector Classification
| Pair | Typical Application | Rating (NA) |
|---|---|---|
| C13 / C14 | Standard Servers & Switches | 15A / 250V |
| C15 / C16 | High-Heat PoE Equipment | 15A / 120°C |
| C19 / C20 | Blade Servers & UPS Units | 20A / 250V |
Design Note: The C15 connector features a specialized notch to prevent "cold" C13 cords from being used in high-heat environments, ensuring hardware integrity and fire safety.
