Data Center Power & Environment Monitoring Control Cabinet

Qingdao Xiaoyang Electric's Data Center Power & Environment Monitoring Control Cabinet integrates power monitoring and environment monitoring in a single enclosure for IDC rooms, cloud computing centers and enterprise data centers. It collects operating data from the mains supply, UPS, distribution circuits, precision air conditioners, temperature/humidity, water leakage, smoke detectors and access control; displays it on a local touch HMI; and raises graded alarms with automatic linkage. Compliant with GB 50174, suitable for Class A/B data center applications.

Product Overview

Power and environment monitoring (PEM) is the foundation of continuous data center operation. As the on-site acquisition and control core of the PEM system, the cabinet connects sensors and smart devices underneath and interfaces with DCIM or PEM platforms above through Modbus/TCP, SNMP and BACnet, making the room visible, alarm-accurate and controllable, and preventing downtime caused by distribution faults, air-conditioner failure, water leakage or temperature excursions.

Core Functions

• Power Monitoring: 3-phase voltage/current/power/energy, breaker and switch status, UPS and battery strings, precision air conditioner parameters
• Environment Monitoring: Temperature/humidity, water leak (rope or positioning type), smoke, access control, infrared intrusion, fresh air and differential pressure
• Alarm & Linkage: Three-level alarms (info/major/critical) via sound-light, SMS, phone call, email and App push; linkage to air conditioners, fans, lighting and access control
• Local & Remote: 10"/15" touch HMI on site, Web/App remote access, local buffering with break-off resume
• Communication & Integration: Modbus RTU/TCP, SNMP v1/v2c, BACnet, MQTT; integration with DCIM, PEM platforms and building automation
• Reliability & Redundancy: Dual power input with automatic transfer, N+1 redundancy for critical modules, hot maintenance supported
