1、 Functional point: Multi skilled in power monitoring

（1） Accurate measurement of full battery capacity

The APM521 electric meter is excellent in measuring electricity, with meticulous measurements of basic electrical parameters such as voltage, current, power, and frequency. Moreover, it can easily handle the measurement of complex electricity quantities such as four quadrant energy, phase separated energy, and multi rate energy, with data accuracy as high as ± 0.2%. Taking industrial production workshops as an example, the operating conditions of various equipment in the workshop are complex, and the electricity consumption situation is constantly changing. APM521 can accurately capture every detail of electricity consumption, providing reliable data for enterprise energy consumption accounting and cost control.

（2） In depth analysis of power quality

The quality of electrical energy is related to the stable operation and lifespan of electrical equipment. APM521 can monitor key indicators of power quality such as current/voltage imbalance, 2-63rd harmonic content, voltage deviation, and frequency deviation in real time, helping users gain insight into the health status of the power grid and locate pollution sources. It is the "outpost" of power quality governance.

（3） Rich and extended functions

The meter comes standard with a feature rich DI/DO module and AO module. Four switch inputs can sense the real-time opening and closing status of switches in the electrical circuit, while two switch outputs can achieve remote control of the equipment. Two 4-20mA analog outputs can meet the monitoring and transmission needs of analog signals. In the intelligent building power distribution system, through these modules, APM521 can be linked with lighting systems, air conditioning systems, etc., intelligently regulating equipment according to electricity consumption, achieving energy conservation and efficiency improvement.

2、 Technical parameter point: High standard performance support

（1） Wide range voltage and current adaptation

The voltage supports 66V~690VAC (L-N/L-L), and the current supports 1A and 5A. This wide range design enables it to adapt to various application scenarios from low voltage distribution to medium and high voltage power grids. Whether it is low-voltage distribution in residential areas or high-voltage power supply in industrial plants, APM521 can work stably and accurately collect data. Moreover, its powerful overload capacity should not be underestimated. It can last for 1 second when the voltage is twice the rated value, and can also last for 1 second when the current is 10 times the rated value. In the face of sudden overload situations in the power grid, it can still stick to its post and ensure uninterrupted data collection.

（2） Excellent electromagnetic compatibility performance

In complex electromagnetic environments, APM521 operates stably without fear of external electromagnetic interference, thanks to its IV level electrostatic discharge immunity and IV level electrical fast transient pulse group immunity. In places with strong electromagnetic interference such as substations, the electromagnetic noise generated by the operation of surrounding equipment is very strong, and ordinary electricity meters may have problems such as data jumping and inaccurate measurement. However, APM521 can accurately measure and ensure the authenticity and reliability of data, providing a solid guarantee for power grid operation monitoring.

（3） Strict safety standards

From a safety perspective, APM521 strictly adheres to safety regulations, with a power frequency withstand voltage of AC4kV/1min and insulation resistance greater than 100M Ω, greatly ensuring the safety of equipment and personnel. In the process of power operation and maintenance, even in the event of unexpected high voltage surges, APM521 can effectively isolate and prevent electric shock accidents, allowing operation and maintenance personnel to operate with peace of mind.

3、 Installation method and location: flexible adaptation to different spaces

（1） Embedded installation

Under the embedded installation method, APM521 adopts a 96 square frame design (frame size 96 × 96mm), which can be appropriately embedded in equipment such as distribution cabinet panels. This installation method is not only beautiful, but also has good protection. In some commercial building power distribution systems with high requirements for equipment appearance, the APM521 embedded installation is integrated with the distribution cabinet, which not only does not occupy additional space, but also achieves accurate power monitoring.

（2） Rail mounted installation

The guide rail installation utilizes a standardized buckle structure, which does not require major modifications to the cabinet structure during installation and can be quickly deployed. In industrial sites, the installation environment of equipment is complex, and the space of distribution cabinets is limited. The APM521 with rail mounted installation can quickly complete the installation without damaging the original layout of the cabinet, and can be easily disassembled and replaced during later maintenance, greatly improving the efficiency of operation and maintenance.

4、 Applicable scenarios: widely used in multiple fields

（1） Industrial sector

In industrial plants, APM521 can monitor the operating status of equipment such as motors, transformers, and distribution cabinets in real time. By analyzing measurement data, it can assist in fault diagnosis. For example, through harmonic analysis function, it can identify the pollution caused by nonlinear loads such as frequency converters to the power grid, help enterprises optimize equipment selection or install filters, reduce equipment losses, and improve production efficiency.

（2） Business field

In commercial complexes, there are numerous equipment such as lighting, air conditioning, elevators, etc., and the electricity load is high and fluctuates frequently. APM521 accurately analyzes the energy consumption of various regions and equipment to assist property management in formulating reasonable electricity consumption strategies, such as utilizing time of use billing functions to activate high energy consuming equipment during low electricity price periods, reducing operating costs, while ensuring power supply reliability and improving customer experience.

（3） Data Center

The data center has high requirements for power supply stability, and APM521 can monitor UPS power supply, diesel generators, distribution circuits, etc. By real-time monitoring of changes in power parameters, ensuring stable power supply for core equipment such as servers, and utilizing its energy efficiency analysis function, optimizing the matching between refrigeration and power supply systems, reducing the PUE value of data centers, and achieving effective energy-saving operation.

（4） In the field of new energy

In new energy scenarios such as photovoltaic power plants and wind power projects, APM521 can monitor the power parameters and energy quality of the grid connected circuit to ensure stable integration between the new energy generation system and the power grid. At the same time, it can accurately measure the power generation, provide key data support for the benefit evaluation and operation management of power stations, and promote the healthy development of the new energy industry.

5、 Safety certification point: UL certification provides protection and protection

APM521 has passed strict UL certification, which has a significant presence in the international market. During the UL certification process, rigorous tests were conducted on the electrical insulation, overcurrent protection, high temperature resistance, fire resistance, and other aspects of the electricity meter. In terms of electrical insulation, ensure that the meter does not pose a risk of electric shock under special conditions such as high voltage and humid environments; The overcurrent protection test verified whether the electric meter can quickly cut off the circuit and avoid equipment damage under overload current. Obtaining UL certification means that APM521 has reached an internationally recognized level in terms of safety performance and quality reliability. Whether it is in domestic projects or exported to regions with strict requirements for electrical product certification such as North America, users can use it with confidence.
