The Acrel AMC100 series data center energy meter delivers high-density multi-loop acquisition for AC and DC distribution cabinets — covering main incoming and every outgoing PDU circuit, with local HMI display, multi-level alarm, and direct Modbus-RTU / Modbus-TCP / SNMP integration with third-party DCIM platforms.
The AMC100 multi-circuit energy meter is purpose-built for data center power distribution — monitoring AC and DC main incoming circuits as well as high-density outgoing PDU and server rack loads. It is the essential instrument for branch-level energy metering and PUE calculation.
Acrel provides complete monitoring from 110kV substation down to IT racks. This page focuses on AMC100 energy monitoring at the precision distribution layer. Click any stage to explore its solution.
AMC100-ZA for AC, AMC100-ZD for DC (-48V / 240V / 360V). Independent A+B main incoming monitoring with full electrical parameters.
Up to 48 single-phase AC or 48 DC outgoing circuits in one DIN-rail module. Track every PDU and server rack branch.
Modbus-RTU / Modbus-TCP / SNMP with 3-way RS485 and optional Ethernet. Plug-and-play with any DCIM, BMS or SCADA.
Configurable thresholds for over-current, over-voltage and communication faults. DI for breaker status, DO relay output.
2nd to 63rd harmonic measurement protects sensitive IT equipment from harmonic distortion and power quality issues.
ATP007kT 7-inch touch screen provides real-time data, trends and alarm logs. Local visualization without upper platform.
Wide operating temperature range and robust EMC performance for 24/7 mission-critical data center operation.
DIN-rail 35mm mounting with solid-core CTs or Hall-effect sensors. Retrofit existing cabinets without shutdown.
Equally suited to greenfield data center projects and brownfield cabinet retrofits. Compact and flexible.
