Inline Meters

Inline Meters

Single and Three-Phase Inline Power Metering

Raritan Inline Meters enable data centers to add real-time intelligent power metering, power-quality monitoring, and optional environmental monitoring to basic, non-intelligent IT equipment and rack PDUs. Non-intrusive installation consists of wiring the inline meter into the existing circuit, without the need to remove or re-cable equipment.

The latest Raritan PX4 Inline Meters provide data centers with real-time insights into current (A), voltage (V), power (kW), energy (kWh), and power factor (PF). With ±0.5% billing-grade metering accuracy, they not only ensure that connected equipment receives the appropriate input, preventing damage and performance degradation, but also enable a confident, trustworthy billing environment.

With built-in remote management capabilities, the inline meter delivers real-time, actionable insight enabling faster troubleshooting, capacity planning, and energy optimization. Enterprise-grade digital security protects connected assets while supporting data center continuity, efficiency, and overall operational performance.

Enhanced Features (enabled on PX4 Inline Meters)

Power Metering & Accuracy

Improved real-time remote circuit-level / line-level monitoring of current, voltage, and crest factor, with ISO/IEC ±0.5% billing-grade metering accuracy.

Advanced Power Quality Monitoring & Metrics

The most complete and accurate rack-level visibility of waveform capture, continuous harmonic distortion monitoring and alerting, and enhanced circuit breaker trip forensics.

Peak & Min/Max Values for Power Measurements

Additional power measurement values can be utilized to determine threshold settings, plan for failover, and easily identify available capacity in the cabinet.

Advanced iX Controller

The upgraded iX Controller integrates high compute power, a display, multiple connectivity ports, Secure Boot with Secure Element key generation, dual gigabit Ethernet, and field-replaceable hot-swappable features for enhanced protection.

Other Features

Flexible Configuration Options

Design to fit your data center needs with voltages from 100V single-phase up to 415V three-phase, form factors from 0U to 2U, and circuit options from 1 to 4 circuits.

Intelligent iX Controller

Experience intelligence with built-in connectivity for environmental and security sensors, serial and KVM devices, USB, and wired or wireless network connections.

Security by Design Architecture

Leverage secure access with advanced authorization and authentication options, including role-based permissions, LDAP/S, RADIUS and Active Directory®, 256-bit AES encryption, and strong passwords.


Local Display and Alarms

Monitor rack power consumption and receive alarms for unbalanced loads based on user-adjustable thresholds. Increase efficiency with load balance lines and circuits

User-Defined Alerts & Thresholds

Define thresholds and receive alerts via SNMP, email, and syslog when thresholds are crossed for both power and environmental events.

Data Logging & Trending

Choose the frequency at which you monitor power and the amount of data gathered to fine-tune power visibility.


Remote Power Monitoring & Metering

Collect, view, and analyze real-time electrical usage data to avoid downtime, improve utilization, reduce costs, and enable remote operations.

Environmental Monitoring & Support

Monitor temperature, humidity, airflow, water/leaks, and other environmental conditions with plug-and-play sensors.

Residual Current Monitoring (RCM) Option

Facilitate early detection of insulation faults and unintended electrical leakage with configurable alarm thresholds, leakage detection, and automated self-testing to ensure ongoing system reliability.


Remote Access & Management

Monitor, configure, and control your inline meter over the network offsite to calibrate for operational efficiency, reliability and uptime, energy optimization, and scalability

Interoperability with DCIM & BMS Systems

Integrate with DCIM and BMS systems for visibility to real-time power loads, trends, and capacity forecasts, and for data center efficiency optimization .

Color-Coding Options

Improve visual feed identification and operational clarity with color-coded chassis and color labels.
