Describe

AMC100-FDK48 is Acrel’s DIN-rail DC precision power-distribution monitoring unit engineered for data-center server racks. It simultaneously tracks full electrical parameters of A+B dual three-phase feeds, 192 outgoing circuits, 8 DI / 4 DO status points, 2 leakage channels, 1 temperature-humidity sensor and 63 harmonics. Three RS485 Modbus-RTU ports enable seamless BMS/DCIM integration. Compact 180 mm housing, ±0.5 % accuracy, per-channel alarm thresholds and instant sound-light warning slash energy waste and downtime, making it the scalable heart of green data-center DC busway or PDU monitoring solutions.
