An important component of data center power monitoring : HEYI Electric HYB-A1 4-20mA current transmitter

Why data centers cannot do without current transmitters 

In the digital information age , data centers are the core of the Internet . We not only need excellent server performance, low network latency , and huge storage capacity, but we must also not ignore the basic energy that supports all of this —electricity.

Electricity is the “lifeline” of the data center, and accurate power monitoring is the key to ensuring system stability and optimizing energy efficiency.

Among thousands of cabinets and PDUs, there is a low-key yet powerful “little character” who is silently guarding the entire system – the HYB-A1 single-phase AC current transmitter .

What is the Heyi HYB-A1 4 20ma current transmitter

It can be called the “electrical translator” of the data center

The core function of the HYB-A1 current transmitter is to convert complex AC current signals into standard signals that can be understood by the monitoring system.Whether it is 1A or 5A input current, the HYB-A1 current transmitter can accurately and safely convert it into a DC 4-20mA or 0-10V DC output signal.

In other words , it turns power data, which was originally difficult to detect , into visual data that can be displayed and analyzed in real time in the BMS, EMS or SCADA system.

HYB-A1 4 20mA current transmitter in data centers

1.Real-time monitoring to prevent power overload

In a high-density cabinet environment, the temporary addition of servers or equipment often leads to a surge in power consumption.

The HYB-A1 4-20mA current transmitter monitors the current changes of each channel in real time. When the load approaches the limit , it will immediately send an early warning signal to the system .

Because it allows 10 times the short-term overload capacity, this current transmitter can not only cope with transient shocks, but also alert operation and maintenance personnel before a fault occurs, avoiding tripping or equipment damage.

2.Accurate energy efficiency analysis to reduce operating costs

Conservative estimates suggest that electricity costs for data centers typically account for around 30% of operating costs .The HYB-A1 4-20mA current transmitter provides reliable current data with a measurement accuracy of up to 0.2%.
With this data, you can:

Analyze the power efficiency of each cabinet or PDU

Improved server layout

Identify ” useless servers” and shut them down promptly.Ultimately achieve precise energy consumption management and cost control .

3.Support predictive maintenance to prevent problems before they occur

When the power module ages or the load is abnormal, the current waveform will fluctuate slightly.

The HYB-A1 current transmitter has a fast response time of ≤400ms and can capture these abnormal signals in time.

Through trend analysis, the operation and maintenance team can take proactive action, shifting from “after-the-fact repairs” to “proactive maintenance,” significantly improving the reliability and availability of the data center.

4.Quadruple electrical isolation to ensure system safety

The power system of a data center is complex and has many interference sources.

The HYB-A1 features a quadruple isolation design for input, output, power supply, and housing, effectively preventing high-voltage interference and signal crosstalk.
This acts like a solid “firewall” for the monitoring system, ensuring stable, safe, and pure power signals.
