Multi-Channel Submeter
AcuRev-4100 Series*
High-Density Branch Circuit Monitoring
AcuRev-4100 Series is a high-density multi-channel AC submeter, designed for revenue-grade metering of multiple loads. Compliant with ANSI C12.20 Class 0.2 and IEC 62053-22 Class 0.2 standards and capable of measuring from 24 current inputs, with 0.2 accuracy. The submeter is engineered for real-time energy consumption monitoring and high-precision power quality analysis in commercial, industrial, and residential facilities.
Key Features
Multi-Circuit Monitoring
Submeter includes up to 24 current inputs (24 single phase, 12 two phase, 8 three phase) for branch circuit monitoring. Its modular design allows up to another 96 expandable channels.
Multi-Protocol Support
Features built-in RS485 interfaces for Modbus RTU and BACnet MS/TP, along with Ethernet for Modbus TCP/IP communication. The optional WEB2 communication module also supports multiple additional industrial protocols, including Modbus TCP/IP, SNMP, MQTT, NTP, SMTP, dual Ethernet, and Wi-Fi.
Input/Output Functions
8 digital outputs and 2 relay outputs for event/alarm indication. 4 digital inputs for status monitoring, SOE logging, or pulse input. Supports 20 alarm groups, monitoring up to 40 parameters with logic combinations, and stores up to 200 alarm logs.
Revenue Grade Accuracy
Compliant to ANSI C12.20 Class 0.2 and IEC 62053-22 Class 0.2 accuracy standards for active energy measurement.
Power Quality Monitoring
Detects power quality events and triggers waveform capture, configurable up to 128 samples per cycle, with a total of 2560 samples captured before and after the trigger.
Multi-Tariff Time of Use
Supports up to four tariffs, including sharp, peak, valley, and normal, with 12 seasons, 14 schedules, 14 segments, weekend settings, and a 10-year holiday calendar for regional billing.
Wiring Configuration
- Supports 24 current inputs, configurable for 24 single-phase, 12 two-phase, 8 three-phase circuits, as well as custom service configuration.
- Software-configurable current mapping allows current transformer inputs to be assigned to logical channels, simplifying installation and wiring corrections.
- Allows current inputs to be paired with voltage inputs for power calculation and energy accumulation.
Data Logging
Includes 3 data loggers and 1 trend logger that can be independently configured for periodic measurement logging. Log data is stored in a non-volatile memory storage, and expandable to 32GB with the communication expansion module.
