Description
The Raritan PX3-4281V is a high-accuracy metered inline PDU engineered for demanding data-center power monitoring. It provides per-line, per-breaker, and per-outlet energy metering with ISO/IEC 62053-21 Class 1 accuracy, ensuring precise visibility into load conditions. Designed for operational reliability, it features dual Ethernet ports for redundant networking, optional Wi-Fi, and support for environmental sensors including temperature, humidity, airflow, differential pressure, water leak, and contact closure.
This 208V single-phase PDU delivers up to 5.0 kVA, equipped with 24 × NEMA 5-20R outlets protected by four 20A circuit breakers. A color LCD display provides local monitoring, while remote access is available via HTTP(s), SSH, SNMP, Modbus TCP, and JSON-RPC. With replaceable controllers, cascading support, and robust build quality, the PX3-4281V is ideal for high-density enterprise rack deployments requiring advanced energy intelligence and dependable performance.
