High Measurement Accuracy: SA2110 adopts a high sampling architecture and advanced signal processing algorithms to ensure reliable measurement results under complex electrical conditions, including environments with significant harmonic distortion.
Real-Time Power Quality Analysis: The instrument provides continuous real-time monitoring of key power quality parameters, allowing users to identify abnormalities as they occur and take corrective action based on accurate data.
Clear and Efficient Operation: With a structured interface and logical parameter configuration, the SA2110 supports efficient operation for engineers, maintenance personnel, and testing professionals without extensive training requirements.
Portable and Field-Ready Design: Designed for both fixed and mobile applications, the SA2110 features a compact structure and durable construction, making it suitable for on-site testing in industrial and commercial environments.
This is the most common application. When mysterious problems occur, the Class S analyzer is deployed to find the culprit.
Intermittent Equipment Failure: Why did a motor controller fail? Why do production line computers randomly reset? The analyzer can capture voltage sags (dips), swells, transients (spikes), or momentary interruptions that are too fast for the human eye or basic meters to see.
Unexplained Tripping: Identifying the cause of nuisance tripping of circuit breakers or protective relays by capturing the exact moment of the trip and the power quality event that caused it.
Flickering Lights: Quantifying voltage flicker (rapid, small changes in voltage) and tracing it back to a specific source, like a large arc furnace or a welding machine starting up.
Many utilities are required by regulators to provide power that meets certain quality standards (e.g., EN 50160 in Europe). Large industrial customers often have contracts specifying acceptable power quality levels.
Utility Side: Utilities use Class S analyzers to prove that the power they are delivering meets regulatory limits for harmonics, voltage variations, and flicker.
Customer Side: Large factories, data centers, and hospitals use them to verify that the power they are receiving is within the contractual agreement. If not, they can use the data as evidence for a claim or rebate.
Before installing sensitive new equipment (e.g., an MRI machine, a semiconductor fabrication tool, or a large data server farm), it's crucial to understand the existing power quality.
Pre-Installation Assessment: A survey over several weeks or months establishes a "power quality baseline." This helps in sizing and specifying the correct protective equipment, like UPS systems or voltage regulators.
Post-Installation Verification: After installation, another survey can confirm that the new equipment is not degrading power quality for other users on the same network (e.g., by generating excessive harmonics).
Renewable Integration: Before connecting a large solar farm or wind turbine to the grid, a study is done to ensure it won't cause voltage fluctuations, harmonic distortion, or flicker that violates grid codes. Class S analyzers are used for this pre-connection assessment and ongoing monitoring.
EV Charging Stations: The start-up of a large, high-power EV charging station can cause significant voltage sags. A Class S analyzer can quantify this impact on the local grid.
The SA2110 is connected to the electrical system under test, supporting single-phase and three-phase power networks.
Measurement parameters such as voltage, current, harmonics, power, and power factor are configured according to the application requirements.
The analyzer continuously measures and records power quality data, which can be viewed locally or exported for further analysis.
When abnormal conditions exceed predefined limits, events are recorded to support diagnostics, reporting, and corrective decision-making.
Warranty Coverage: SA2110 is supplied with a standard 1-year warranty covering manufacturing and material defects, ensuring product reliability throughout its service period.
Technical Support Services: Professional technical support is available to assist customers with installation, configuration, troubleshooting, and application guidance, ensuring stable and correct operation in different use cases.
Training and Documentation: Comprehensive user manuals and technical documentation are provided. Online training and application guidance are available, with on-site technical support offered for project-based requirements.
SA2110 can measure voltage up to 1000 V AC and DC with the standard accessories--- voltage test leads and alligator clips.
100th harmonics measuring requirement can be realized in SA2110, together with new added function---harmonic power.
SA2110 can measure up to 3000 Hz high frequency signal, and superimpose it to the standard 50/60 Hz low-voltage alternating current(AC) waveform to realize remote controlling the large consumer loads' on and off.
Inverter efficiency is important in the new energy field, which can show the energy consumption during the energy conversion from DC to AC.
5.6" color LCD touch screen with new user interface is more user-friendly during the power and energy measuring.
