HYB-A1 High-Reliability Outdoor Current Transmitter – Born for Harsh Environments

In applications such as energy, industrial automation, and smart power distribution, current transmitters may seem ordinary, but they are indispensable. They don’t attract as much attention as inverters, nor do they have the imposing presence of circuit breakers. However, the safety of system operation and the accuracy of data often depend on their stability.

However, once it’s placed outdoors, the situation is quite different.

intense heat, humidity , strong electromagnetic interference, sand and dust…

For ordinary transmitters, this is undoubtedly “hell mode”.

Thus, HYB-A1 was born—it was never designed for greenhouse environments from the outset.

It is specifically designed for harsh outdoor environments and is a rugged piece of equipment that can withstand the test.

Why must high-specification current transmitters be used outdoors

High temperature resistance and stable performance

Do you think 40℃ is hot?

In summer, the temperature inside outdoor power distribution cabinets can easily exceed 60°C, making the equipment feel like it’s in a sauna.

At this point, most transmitters had already begun to drift, but the HYB-A1 was completely different:

• It can operate stably for a long time in an environment of 0~50℃.
• Its outer shell is made of high-temperature resistant and flame-retardant ABS material.
• All internal components are low-temperature drift and high-stability elements .

Even in an “oven-like” environment, it can still reliably transmit data.

Excellent moisture-proof performance, unaffected by humid environments.

The humidity inside photovoltaic boxes and wind turbine tower cabinets is between 70% and 90% year-round, and condensation may even occur.

How does the HYB-A1 meet this challenge?

• It adopts a sealed structure combined with a moisture-proof design.
• It can operate stably in environments with humidity below 80% (no condensation).

In other words, while other similar products treat moisture protection as a major threat, it handles it as a trivial daily matter with ease.

Strong anti-interference capability, clear and stable signal.

Photovoltaic inverters, transformers, high-voltage lines… these places are all sources of interference.

HYB – A1‘s response was very direct:

• It features quadruple isolation: input isolation, output isolation, power supply isolation, and enclosure isolation.
• The power frequency withstand voltage can reach AC 2000V.
• The insulation resistance is not less than 100MΩ.

When faced with strong interference, it treats it as nothing more than a routine matter.

It successfully addressed several key concerns of engineers.

• Stable accuracy : It boasts high accuracy of 0.2%/0.5%, a response time of no more than 400ms, and an output ripple of no more than 0.5% RO. It performs reliably in applications with stringent data requirements, such as SCADA and power quality monitoring.
• Comprehensive measurement range and strong overload capacity : Supports 0.1A/1A/5A/10A and CT secondary side signals, and can also be customized according to requirements. Its overload capacity is also excellent, capable of withstanding twice the rated current for a long time, and can operate continuously for 10 seconds at 10 times the rated current.
• Universal output interface : Supports 4-20mA, 0-10V, and 0-5V outputs. It can be easily connected to PLC, DCS, EMS, SCADA, BMS, and other systems, essentially achieving plug-and-play functionality.
• Wide power supply range and strong adaptability : It has a wide voltage input range of 80-270V, which can effectively cope with large voltage fluctuations in outdoor cabinets. It also supports customized DC 12V/24V/48V power supplies.
• Easy to adjust : The front panel features direct ZERO/SPAN fine-tuning. Engineers know that minimizing the need to remove the cover and rework is far more important than anything else.
• Easy to install : Measuring 120×55×75mm, it can be directly mounted on a 35mm guide rail. The casing is made of flame-retardant ABS material, making it lightweight yet sturdy, and the assembly process is quick and efficient.

Current transmitter are mainly installed in the following types of equipment:

Typical application scenarios are its home turf .

• Photovoltaic power plants : They perform combiner box current monitoring, string health diagnosis, and EMS data upload—even when the enclosure temperature is extremely high, it can still operate stably.
• Wind turbine tower : Its internal environment is cold and damp, with strong winds and interference, but it has long been adapted to such an environment.
• Outdoor distribution cabinets/power systems : enable motor protection, circuit monitoring and remote power distribution management. Its quadruple isolation design is particularly well-suited to the power industry’s high safety requirements.

Industrial automation : It can monitor the load current of large motors, heating equipment, transformers, etc., detect abnormal conditions in advance, and avoid unplanned downtime.

In short, the HYB-A1 transmitter is a device that engineers can basically trust after installation.

Its features can be summarized as: heat resistance, moisture resistance, anti-interference, strong overload capacity, stable data output, and peace of mind.

benefits does it bring ?

More accurate data, less maintenance, more reliable systems, and lower project failure rates.

If your project is located in an outdoor environment with high temperature, high humidity, or strong interference, then the HYB-A1 may be the partner you have been looking for—the kind of partner that is more reliable in harsher environments.
