Accuenergy AcuRev 1320 Class 0.1S DIN Rail Energy Meter

AcuRev 1320 is the Accuenergy revenue-grade DIN rail series with IEC 62053-22 class 0.1S measurement. The AcuRev-1321 is the energy meter and the AcuRev-1322 adds IEC 61000-4-30 class S power quality analysis. Both have dual Ethernet ports, RS485, three digital inputs and one digital output in a compact panel housing.

Class 0.1S metering with logging and power quality in one DIN module

The series measures three voltage inputs from 69 to 480 Vac line-to-neutral (830 Vac line-to-line) and four current channels, with 0.1 percent accuracy on voltage, current, power and energy. Services supported include 1E2W, 2E3W single-phase, 2E3W delta, 2E3W network, 3E4W high-leg delta and 3E4W wye.

Three independent data loggers and one trend logger record periodic readings, while audit logs and a 5000-event system log give a trail for metering integrity and troubleshooting. Four tariffs with 14 schedules, 12 seasons and a 10-year holiday calendar support time-of-use billing. An HTTPS web server and optional HTTP/HTTPS data post to AcuCloud give remote access.

Features stated in the datasheet

• Dual-source energy: records grid and generation energy separately, using switching logic to attribute energy to the active source.
• Software current-channel remapping and forward or reverse direction, to correct wiring errors without rewiring.
• 20 alarms monitoring up to 40 parameters with AND/OR logic and 200 alarm records.
• AcuRev-1322 only: 1-cycle update, harmonics up to the 63rd, flicker (Pinst, Pst, Plt), sag, swell, interruption and unbalance events and up to 200 waveforms.

Technical specification

Measurement and power quality (datasheet)

Inputs, communication and environment

Ordering codes and variants

The code is Meter Model – Current Input. Models are AcuRev-1321 (revenue-grade energy meter) and AcuRev-1322 (advanced power quality analyzer); current inputs are mA (80 mA and 100 mA) or mV (333 mV and 120 mV Rogowski coil). Printed examples are AcuRev-1321-mA and AcuRev-1322-mV.

Regional suffixes exist: MC for Measurement Canada, CP for California Type Evaluation Program (mV, 333 mV) and MD for legal metrology (MID) certification. The datasheet recommends mounting the unit in a cabinet rated IP54 or better.

Wiring, set-up and commissioning

Wiring diagrams cover 1 element 2 wire, 2 element 3 wire single phase, delta and network, and 3 element 4 wire wye and delta connections, each with 1 A fuses on the voltage inputs. An optional human-machine interface shows real-time data and allows configuration without a laptop.

Firmware can be updated over Ethernet or RS485, and the web server offers real-time readings and configuration over HTTPS. Time synchronisation uses SNTP.

Applications named in the datasheet

Accuenergy lists building management integration, industrial and commercial energy management, DER monitoring, tenant billing, railway and subway systems, data centres and PDUs, utilities and grid-plus-PV source monitoring.

General engineering note: the dual-source logic is useful in sites that run mains and a diesel or solar source, where energy must be split by supply for allocation.

Commissioning and enquiry notes

Set the wiring mode, CT ratios and network settings at commissioning, and synchronise the clock so logged data and events line up with other systems. Check the panel’s internal temperature in summer.
