The Raritan PX-2000 family of high-quality, intelligent rack power distribution units (iPDUs) offers real-time remote unit-level power monitoring of current (amps), voltage, power (kVA, kW), power factor and energy consumption (kWh) with ISO/IEC +/- 1% billing-grade accuracy. The PX-2000 also supports Raritan's plug-and-play environmental sensors. Users can define thresholds and receive alerts when thresholds are crossed for both power and environmental events.
