AP4421 Rack ATS (Automatic Transfer Switch) by Schneider Electric. Keeps single-corded IT equipment powered with redundant AC sources—automatically switches between primary and secondary input to maintain power continuity. Critical for avoiding downtime in rack-mount setups.
Rated 10A, 230V max input capacity. Dual IEC C14 input connectors. Utilizes IEC C13 output connectors for connected devices—8 total outputs for distribution flexibility. Compact rack-mountable form factor (~1U size). Switching happens when the source falls out of range, monitored voltage thresholds.
Dimensions: fit standard racks easily; lightweight (~2kg or less, check exact spec). Voltage monitoring checks A+B source input constantly; minimal transfer delay under typical conditions (<10ms reported). LED status indicators on front panel—quick at-a-glance understanding of active supply and fault scenarios.
Technical notes:
- Input voltage: nominal 230V AC, range ~200–240V AC.
- Max load current per phase: 10A/2300W total throughput capacity across outputs.
- Connector types: In = IEC C14 x2, Out = IEC C13 x8.
- Rack height footprint ~1U-ish.
- Operating temp range unspecified but estimated standard range ~0°C to +45°C likely okay.
- Shared Source Mode feature optional-enable (?) unclear doc detail here.
- Manufactured by Schneider Electric, product line consistency unknown reference cycle specifics
