Data Center DC Power System Precision Energy Management Solution

The data center power distribution cabinet/row head cabinet (PDM or RPP) monitoring system can realize centralized monitoring and display of the switch status, alarm status, voltage, current, power and other power parameters of the incoming and outgoing circuits (single-phase, three-phase, AC and DC) of the row head cabinet, thereby improving the safety and reliability of the power supply of IT equipment in the data center.

AMC Precision Power Distribution Monitoring Solution is a complete solution designed and developed for the monitoring requirements of precision power distribution cabinets, including AC 220V and DC 48V/240V/336V systems:

Composed of ≥ 7 inch HMI, integrated information processing host module, switch status acquisition module,current transformer or Hall sensor acquisition unit module, etc.

This solution was designed for precision sub energy monitoring of DC Data Center.Normally, the power system of DC data center will be supplied by 2 independent mains supply for the stable and sustainable operation. And the most important loads of data center will be IT equipments powered by PDU sourced from Main DC power distribution cabinet for these loads. Thus, the monitoring to this Main DC power distribution cabinet of both dual incoming DC circuits sourced from 2 independant mains supply and multiple outgoing circuits for powering all PDU will be a key for a precise submetering of data center's DC power system.
This solution was majorly for local energy monitoring, different from Acrel IoT Cloud energy monitoring solution which is designed for DC Data Center online cloud energy monitoring. In other hands, this solution could be also adapted to 3rd party IoT energy monitoring system by the integration between Acrel energy meter to 3rd party IoT gateways via RS485 [MODBUS-RTU protocol]. Or by the integration between Acrel IoT gateway and 3rd party IoT system via 4G, WiFi, Ethernet [MQTT or MODBUS-TCP protocol].

IoT Energy Monitoring is the trend of future. So, if the customer/your side already have your own IoT system platform but don't have IoT gateway which has been already integrated with your IoT system. And in this case you don't need Acrel IoT system, but you want to receive the data from Acrel Energy Meter to your system instead. Then, the integration between Acrel AWT200-1E4S Series IoT gateway [either 4G, WiFi or Ethernet version] and your IoT system based on either MQTT or MODBUS-TCP protocol will be the key for overall system integration.
(1)Both AMC100-ZD Multi-channel DC Energy Meter and AWT200-1E4S IoT gateway support RS485 communications based on MODBUS-RTU protocol. And between these devices, the integration of RS485 [MODBUS-RTU] part has been already done in factory stage. [Since they are all Acrel produced products]
(2)Thus, to make the overall communications structure complete, we only need to do the integration between Acrel AWT200-1E4S Series IoT gateway with your IoT system via 4G, WiFi or Ethernet communications methods based on either MQTT or MODBUS-TCP protocol. To do this part, Acrel side will provide either MQTT or MODBUS-TCP protocol file to your side for system integration.

Similarly, Acrel also has our own IoT platform, and you can also buy out our cloud platform for energy consumption monitoring.
