AcuRev 1320 Series
DIN Rail Power & Energy Meter
The AcuRev 1320 Series is a compact DIN rail power and energy meter ideal in panel enclosure builds where clean wiring management is essential. It is designed for three-phase energy metering for multi-unit billing and building management applications. The AcuRev-1322 model supports advanced power quality monitoring compliant to IEC 61000-4-30 and IEC 62586 Class S.
AcuRev 1320 Series Features
DIN Rail Design for Efficient Panel Integration
The AcuRev 1320 Series is designed for DIN rail installation, with top and bottom terminals that enable efficient wiring in panel enclosure. This configuration improves cable routing, reduces wiring congestion between adjacent devices, and simplifies installation. Its compact, side-by-side mounting on a standard TS35 rail supports higher panel density and flexible system expansion.
Accessible terminals support easier maintenance and replacement. The meters integrate seamlessly with relays, PLCs, contactors, and I/O modules, making it suitable for integration across a wide range of enclosure types, including: Control cabinets, utility cabinets, substation control cabinets, inverter cabinets.
Revenue-Grade Accuracy
Meets IEC 62053-22 Class 0.1S standard for active energy measurement, delivering 0.1% accuracy. Measures three voltage inputs and four current inputs. Supports multiple service configurations for single-phase and three-phase wiring systems.
Power Quality Monitoring
The AcuRev-1322 power meter complies with IEC 61000-4-30 and IEC 62586 Class S standards for PQ monitoring. Detects up to 200 PQ events and supports waveform capture triggered by DI trigger, manual command, or PQ events, storing up to 200 waveform records with sampling up to 512 samples per cycle.
Advanced Metering
Independent input channels allow each current input to be paired with any voltage input for flexible power calculation and energy accumulation.
Supports dual source energy for applications with two energy sources, enabling separate energy accumulation for grid and generation. Source selection is controlled through switching logic to record the active energy source.
Flexible Wiring Configuration
Software-configurable wiring with current channel remapping to correct wiring errors. Current input direction allows forward or reverse configuration to correct reversed input connections.
Multi-Protocol Support
Built-in RS485 interface for Modbus RTU and BACnet MS/TP, and dual Ethernet ports for Modbus TCP/IP. An integrated HTTPS web server enables remote data access and device configuration. Supports data posts via HTTPS and integration with AcuCloud.
Built-in Data Logging and System Logs
Provides three data loggers and one trend logger, each independently configurable for periodic measurement logging. Includes audit and system event logs. The audit log records user activities and configuration changes to maintain metering integrity and support compliance. The system event log records device operational events such as status changes, communication events, and system faults for monitoring and troubleshooting.
Alarm Monitoring
Supports 20 alarm groups, monitors up to 40 parameters with logic combinations, and stores up to 200 alarm logs.
Multi-Tariff Time of Use (TOU)
Up to 4 tariffs (sharp, peak, valley, normal) with 14 schedules, 14 segments, weekend settings, and a 10-year holiday calendar for regional billing.
Built-in and Expandable I/O Functions
Includes 3 digital inputs configurable for status monitoring, SOE logging, or pulse input. Supports 1 digital output configurable for event and alarm triggering or pulse output. An optional I/O module extends the inputs and outputs functionality with additional DI and DO.
