Smart Precision AC Power Distribution Unit
Intelligent Precision AC Power Distribution Unit (Row Cabinet): This device is a high-precision, end-of-line power distribution and monitoring system specifically designed for modern data center facilities and critical IT power distribution environments. The equipment is suitable for 380V/220V low-voltage power distribution systems, with a rated current capacity reaching up to 630A. Utilizing advanced microprocessor-based digital measurement technology, the system enables continuous, high-precision monitoring—via a local high-definition touchscreen interface—of voltage, current, power consumption, and harmonics across both the main input circuit and dozens of output branch circuits.
Description
Technical Advantages
1.Comprehensive Branch-Circuit Monitoring:
Beyond measuring the total circuit, the system independently monitors the current, power, energy consumption, and three-phase imbalance of every individual output branch protected by a miniature circuit breaker (MCB). This enables data centers to achieve precise, per-cabinet energy metering and analysis.
2.Harmonic and Power Quality Analysis:
Equipped with a high-performance digital sampling chip, the system supports in-depth analysis of the total circuit’s waveforms, frequency, and harmonic distortion levels. This effectively mitigates power disturbances caused by non-linear IT loads that could otherwise impact sensitive equipment within the server room.
3.Multi-Protocol Smart Gateway (Smart Telemetry & RS485):
Featuring a standard industrial-grade RS485 communication interface, the unit supports Modbus RTU and other mainstream environmental and power monitoring protocols used in data centers. It uploads all electrical parameters in real-time to the central control room’s DCS or BMS, facilitating “Four-Remote” (telemetry, telecontrol, telesignaling, and teleadjustment) intelligent remote operation and maintenance.
4.Highly Modular and Secure Design:
The cabinet is available in a variety of standardized dimensions (widths ranging from 600mm to 1200mm). Its internal layout features a clear and organized arrangement of high- and low-voltage components, complemented by independent temperature and humidity monitoring capabilities. Field wiring is simplified, and the unit offers flexible installation options—either floor-standing or wall-mounted—to adapt optimally to the available space within the server room.
