· 4-channel digital outputs for alarm & control functions

· Optional leakage current & temperature/humidity monitoring

Product Portfolio

System Architecture

Dual-Redundant Power Structure

Our solution maps directly to Tier-3/Tier-4 data center designs with A/B side independent mains supplies, UPS systems, and PDU distribution — ensuring full visibility across the entire power chain.

Three Integration Pathways

1. Local Standalone System

· AMC100 series meters + ATP007kT HMI

· Ideal for cabinet-level local monitoring

· No network dependency required

2. Customer IoT Gateway Integration

· AMC100-ZA → Customer's IoT gateway via RS485 Modbus-RTU

· Perfect for clients with existing IoT platforms

· Acrel provides full Modbus protocol documentation

3. Acrel Gateway + Customer Cloud

· AMC100 meters → AWT200 gateway → Customer's cloud platform

· Supports MQTT & Modbus-TCP protocols

· 4G/WiFi/Ethernet connectivity options

Typical Application Scenario

For a standard AC data center cabinet deployment:

· 2× Main incoming 3-phase circuits(600A class) — monitored by AMC100-ZA

· 10× 3-phase outgoing circuits(32A) to 3-phase PDUs — monitored by AMC100-FAK30

· 48× 1-phase outgoing circuits(32A) to single-phase server racks — monitored by AMC100-FAK48

· Centralized HMIfor real-time display, alarm management, and local configuration
