In the energy management of industry and modern buildings, scenarios such as electric motors, lighting, air compressors, heating and ventilation systems require: Air conditioning and automated control systems provide a very high degree of continuity, accuracy and safety in the current monitoring. Introduced by Wenzhou Heyi Electric Co., Ltd., the HK-816L series split core current transformer was specifically developed for the needs of these scenarios. Its driveless mounting and the characteristics of standard signal output of 4-20mA make it an ideal choice for protecting equipment and improving energy efficiency.

1. Main advantages of the product

 

HK-816L is based on a split clamping design that can be mounted directly to cables or buses during equipment operation. A high-precision built-in module converts the basic current linearly into a standard signal of 4-20mA DC that can be connected directly to PLC, DCS and other systems. As a high precision ac current transformer, it provides reliable data for precise regulation. It covers a range from 250A to 5000A to meet the most diverse requirements from the lighting industry to the main buses.

2.Typical application scenarios

 

2.1 Industrial equipment: electric motors and air compressors

 

The air compressor 300A in a particular plant often suffers from overload and stops. The HK-816L-400 converter is mounted on the power line without interrupt card and the power signal is connected to the PLC. It automatically warns against exceeding the limit, prevents many outages and ensures continuous production. In large workshops, the HK-816L cards are mounted in the input line for each engine and the data is centralized in the control hall. Management staff can monitor the condition of the plant in real time, perform maintenance on time and effectively prevent accidents.split core current transformer

2.2 Building energy: lighting and ventilation systems

 

A certain complex requires the measurement of the underposition of lighting energy consumption, but conventional processors cannot be installed when the distribution cabinet is alive. By installing the uninterrupted HK-816L-600 network card, data is transmitted to the energy management system, which facilitates the maintenance of energy consumption statistics for lighting in various areas. ventilation system in the underground garage starts and stops at the original time, which consumes a lot of energy; After mounting the HK-816L on each fan, the workload is automatically adjusted to the movement flow and CO concentration, resulting in significant energy savings. This low voltage current transformer has great advantages in converting the energy output into a low voltage distribution.

 

2.3 Air conditioning and automation: Air conditioning and control

 

The air conditioning in a certain electronics factory works all year round. The HK-816L-800 is mounted on the main voltage source 600A to monitor the three-phase current in real time. When the cooling water pump drops in power, the system is automatically converted to a spare pump to ensure environmental stability. The central air conditioning of the commercial complex has many compressors and collects the HK-816L power in each unit. The automatic control system adjusts the frequency of the cooling water pump accordingly, is comfortable and energy-saving. Its design takes into account the expansion of conductive current control and can be used as a circular residential current transformer to increase electrical safety.split core current transformer

3. Selection guide

 

Choose HK-816L-250 for a small current (0-250A) used for lighting branches and small motors; Choose HK-816L-1000 for the medium current (0-1000A) used for air compressors, air conditioners and ventilation equipment; HK-816L-5000 was selected for high current (0-5000A) and used on the output side of the main bus and converter. The technical team will assist you in the selection to ensure the best possible performance of each split core current transformer.

 

4. Conclusion

 

The HK-816L series split core current transformers are characterized by uninterrupted assembly, high measurement accuracy and the generation of a standard signal as the basis, full integration in scenarios such as electric motors, air compressors, lighting, adaptation, Adaptation and control through automation and provide reliable and effective power control solutions for modern industries and buildings.
