Nowadays, many factories are highly automated, and the accuracy of data is particularly critical, which directly affects the stability of the system, smooth production, and safety.
In the power system, current transformers are like the "eyes" of the system, and their usability is particularly important.
However, the on-site environment is often quite complex, especially the electromagnetic interference caused by frequency converters and high-power equipment, which often causes old-fashioned current transformers to "trip" - data suddenly jumps back and forth, inaccurate measurement, and in severe cases, the system may misjudge and act randomly.
This has also become a technical challenge that many operating units are particularly troubled by.
1.1 Small in size, capable: KCT-16L series
Let's first take a look at the KCT-16L series, which is an open-loop Hall current transformer. To put it simply, its most eye-catching feature is its compact size, which is particularly popular in the market.
This series has a wide range of models, including commonly used specifications such as 50A, 100A, 150A, and 200A, which can basically accommodate common measurement scenarios.
Taking the KCT-16L-50A model as an example, it not only maintains its compact size, but also has high measurement accuracy. So if you encounter a place where installation space is particularly tight, choosing it is particularly suitable. It outputs a standard signal of 4~20mA with an accuracy of ± 1%. It is particularly convenient and easy to connect to the system, making it an ideal choice for various small automation equipment.
1.2 The cornerstone of stability: KCT-24L series
This KCT-24L series focuses on measuring medium current. From 100A to 400A, there are a wide range of specifications and choices, and it can basically handle tasks within this range.
Technically, it is also quite sophisticated, using better magnetic core materials and upgrading the winding process. The direct benefit of doing so is that its frequency response range is particularly wide.
Take the KCT-24L-400A model as an example, it can not only measure high currents of 400A, but also cover a wide frequency range from 20Hz to 20000Hz. What does this represent? That means even if the current changes quickly and complexly, it can accurately capture it without losing any details.
So in industrial automation sites with complex environments, using this product is particularly practical, stable, and reliable. It is not an exaggeration to say that it is a "reassurance pill" in the system.
1.3 Strength oriented, specializing in heavy work: KCT-36L series
The KCT-36L series is specifically designed to deal with high current and harsh environmental situations. Its product line is very comprehensive, covering from 200A to 600A, naturally designed for heavy work.
Take the KCT-36L-600A model inside as an example, with a rated current of up to 600A and ultra fast response time of less than 200 milliseconds. What does this mean? That is to say, when the current changes on the high-power device side, it can immediately capture it, making the system run more stably and less prone to problems.
Not only that, this series has also been specially strengthened in terms of insulation, with an insulation strength of up to 5000 volts. This is like adding a particularly reliable security firewall to dangerous scenarios with high voltage and high current, which makes you feel much more at ease when using it.
1.4 Exclusive customization, tailored for you
In addition to the existing standard models, our KCT series also supports professional customization. Simply put, you can flexibly adjust the input and output currents according to your actual needs, so that the product can perfectly match your special application.
It is precisely because of this deep customization ability that KCT current transformers can easily handle various complex working conditions, and perform particularly flexibly and adaptable in different industries and diverse scenarios.
2.1 Split design, this improvement is too practical
The KCT series current transformers feature a particularly clever design - a split structure. Take the KCT-16-2L (24V) model as an example, it adopts a unique open close structure, coupled with an external integrator and crimping terminal output, so there is no need to cut the main line during installation.
This design is really convenient to use, it can be said to completely simplify the complex installation method of traditional current transformers. Especially during system upgrades or on-site repairs, it can save you a lot of trouble, especially time and effort.
2.2 Environmental adaptability, indeed quite capable of withstanding
The environmental adaptability of the KCT series is indeed good. Take KCT-16-2L (24V) as an example, it can work normally from minus 10 degrees Celsius to over 60 degrees Celsius during operation; When stored, it can better adapt to temperature differences between minus 10 degrees and 70 degrees. Moreover, it can maintain stable operation in various complex environments below an altitude of 1000 meters.
This is mainly attributed to its solid workmanship and excellent protection. So, even in industrial environments where interference from gases, vapors, or chemical deposits is frequent, it can still maintain reliability and steadily respond to various harsh challenges in the long run.
2.3 Accurate and Stable Measurement
The KCT series does a great job in measuring accuracy. Taking the KCT-16-2L (24V) as an example, its accuracy and linearity are controlled within 0.5%, and the zero drift is particularly small, not exceeding ± 0.03mA.
In addition, it has a wide bandwidth of 25Hz to 1kHz, so even if the electromagnetic environment on site is complex, it can maintain high-precision measurements. In this way, the data is both accurate and reliable, providing a very solid guarantee for system control and fault diagnosis.
In the field of photovoltaic new energy, our KCT-24L-100A current transformer is particularly "manufactured". It has strong anti-interference ability and good temperature stability, making it the first choice for monitoring current in photovoltaic inverter stations.
Even in such a large temperature difference of minus 40 degrees to plus 85 degrees, it remains stable and reliable in various harsh outdoor environments, never losing its grip.
When it comes to rail transit, we have to mention our KCT-36L-400A. It has two particularly impressive advantages: one is its ability to withstand overload, and the other is its fast response speed.
Its response time can be controlled within 200 milliseconds, which means that the system can instantly capture subtle changes in current, providing a "safety" for the safe operation of the train.
In the field of industrial automation, the KCT-16L-50A is widely used. People like it mainly for two reasons: one is its compact size, and the other is its accurate measurement.
It can often be seen in devices such as frequency converters and frequency controllers. It outputs a standard signal of 4~20mA, which can be directly integrated with mainstream control systems without additional hassle, making it particularly convenient. The system integration has become simpler, and the efficiency of engineering installation has naturally improved.
Choosing KCT series current transformers is not only due to their excellent technology, but more importantly, it allows you to see tangible returns.
Take KCT-16-2L (24V) as an example, its accuracy reaches level 0.5, which can make electricity metering particularly accurate, helping enterprises manage electricity consumption more finely and directly save money on electricity bills. At the same time, its insulation strength is 2.5KV, which is equivalent to adding a lock to the safe operation of the equipment, making it more reassuring to use.
The frequency response range of KCT-24L series is particularly wide, covering from 20 to 20000 Hz. It can accurately capture even the most complex harmonic current signals, which is particularly helpful for power quality analysis.
The KCT-36L series has a very strong overload capacity, capable of withstanding up to 120% of the rated current. Even if there is a sudden fluctuation in the on-site current, it can remain stable and will not easily break down, which can effectively protect the more expensive equipment in the backend.
