High-density hot-swappable power distribution unit NEMA4X available now

Raritan PX4 and Larson Electronics NEMA 4X PDUs provide high-density, hot-swappable power distribution solutions suitable for industrial and data center environments.Raritan PX4 PDU

The PX4 PDU is designed for high-density rack deployments with patented HDOT outlets that combine C13 and C19 functionality, accommodating both C14 and C20 plugs in a single outlet. It supports hot-swappable operation, allowing live replacement of individual outlets without interrupting power to connected equipment. The PX4 also offers real-time power monitoring with ±0.5% accuracy, tracking metrics such as total harmonic distortion, reactive power, and inrush current. Its modular design maximizes outlet density in a 42U rack, reducing the need for multiple PDUs and simplifying future equipment upgrades .

Larson Electronics NEMA 4X PDU

For industrial and outdoor applications, the Larson Electronics PDU-PNL-SS-3P-MCB-400A-480Y.277-N4X provides a NEMA 4X-rated enclosure, protecting against dust, dirt, and moisture. This 400-amp, three-phase 480Y/277V AC panel includes 42 circuits and a main circuit breaker. The stainless steel enclosure supports plug-in mounting, lockable access, and optional configurations on dolly carts or stand-alone frames for flexible deployment. It is UL 1640 certified, ensuring compliance with industrial safety standards .

CoolIT CHx2000 CDU

While primarily a liquid-to-air cooling distribution unit, the CHx2000 features hot-swappable pumps and full monitoring capabilities, making it suitable for high-density data center environments where both power and thermal management are critical. It supports up to 2000 kW capacity and integrates seamlessly with existing infrastructure .

Summary
  • Raritan PX4: High-density, hot-swappable outlets, real-time monitoring, ideal for data centers.
  • Larson Electronics NEMA 4X PDU: Rugged, industrial-grade, NEMA 4X enclosure, 42 circuits, 400A three-phase.
