Accuenergy has announced the AcuRev 4100 Series, a multi-channel branch-circuit submeter for real-time energy metering and power-quality monitoring. Accuenergy says the meter is compliant with ANSI C12.20 Class 0.2 and IEC 62053-22 Class 0.2S and supports up to 24 current inputs, targeting applications that need granular circuit-level measurement for billing and performance analysis.
Accuenergy positions the AcuRev 4100 for complex electrical distribution environments facing stricter metering requirements, including data centers with increasing power density. The company says each submeter supports 24 current inputs configurable as 24 single-phase, 12 two-phase, eight three-phase, or other custom circuit arrangements. It also includes current mapping and the ability to pair any current input with any voltage input for flexible power calculation and energy accumulation.
For diagnostics and long-term analysis, Accuenergy says the AcuRev 4100 combines power-quality monitoring, data logging, and communications in one unit. Event-triggered waveform capture records up to 2,560 samples per event (up to 128 samples per cycle), and the unit includes three data loggers plus one trend logger, each independently configurable. Connectivity includes RS485 and dual Ethernet ports providing Modbus and BACnet connectivity, with dual Ethernet supporting Rapid Spanning Tree Protocol (RSTP) networking over Modbus.
Accuenergy specifically calls out data center deployments, stating the AcuRev 4100 is designed to monitor individual circuits within power distribution units (PDUs) and remote power panels. The company says this provides per-rack energy data, load-balancing insight, and available-capacity tracking for overload prevention, phase-distribution optimization, and billing in colocation environments.
“In modern data centers, where high-density PDUs and remote power panels demand accurate, real-time circuit-level visibility for capacity planning, tenant billing, and load management,” said Howard Wang, President of Accuenergy. “Many legacy submeters lack the channel density and communication flexibility required in these environments. The AcuRev 4100 delivers revenue-grade accuracy, integrated power quality analysis, and scalable multi-circuit architecture to support high-density branch circuit monitoring in critical systems.”
Additional features listed by Accuenergy include four digital inputs (for status monitoring, sequence-of-events logging, or pulse input); eight digital outputs and two relay outputs (for event and alarm triggering and control); monitoring for 40 parameters; 20 configurable alarm groups; and 200 alarm logs. Accuenergy also offers an optional ACM-41-WEB2 module that adds up to 32 GB memory, SNMP, HTTPS, FTP, SFTP, Network Time Protocol (NTP), MQTT, SMTP, Wi-Fi, and direct cloud access via AcuCloud, plus an optional web interface and built-in web server for remote monitoring of real-time metering data. The company also states the product is UL Listed and Measurement Canada approved.
