The IT7900E series is a programmable, four-quadrant grid simulator. It is also a four-quadrant power amplifier, which can be used to test various grid-connected equipment.

For example, PCS, energy storage system, microgrid, BOBC (V2X), PHiL, etc. With advanced SiC technolgoy, a single unit of IT7900E can realize the anti-islanding protection test through islanding mode(RLC settable). Besides, the power density of IT7900E series is very high, 6kVA in 1U, 21kVA in 3U. After parallel connection, the power can be extended to 960kVA at most. 

Adopting advanced SiC technology, the IT7900EP Series High-Performance Regenerative Grid Simulator provides an all-in-one test solution that can be used not only as a grid simulator and four-quadrant power amplifier, but also as a four-quadrant regenerative AC/DC electronic load.

The full four-quadrant operation, regenerative ability can feedback power to the grid, meet the needs of environmental protection, but also save a lot of electricity and heat dissipation costs.

IT7900 series represents a new generation of programmable, full four-quadrant grid simulators that can also be used as fourquadrant power amplifiers for testing all kinds of grid-connected products.

Examples include PCS, energy storage systems,micro-grids, BOBC (V2X) and power related hardware loop simulation (PHiL). With the energy regenerative function, it provides 100% current absorption and feeds back to the grid through the device, saving power and cooling costs.

The IT7800 series is a new generation of high power programmable AC power supply featuring user-friendly programming options, a novel touch interface, and rich waveform analysis capabilities.

The high-voltage series is available at voltages as high as 700 VL-N and even fulfills 1050 VL-N test standards. By paralleling them, the high voltage series may be easily enlarged to 900 kVA.

Earthquake Early Warning System

Every second counts. The Earthquake Early Warning System (EEWS) developed by Sanlien can detect earthquakes before they arrive. The advance warning allows people to take action to escape from disasters.

Building Structural Health Monitoring (SHM) is a vital discipline in civil engineering, focusing on assessing and monitoring the safety, condition, and performance of structures like buildings and bridges. SHM uses real-time data, including factors like vibrations and strains, to detect issues, predict problems, and inform maintenance decisions for these structures, ensuring their longevity and safety in an ever-advancing technological landscape.

Enhancing Foundation and Deep Excavation Monitoring for Safer Infrastructure

Geotechnical monitoring is vital for slope and landslide safety, and the integration of Narrowband Internet of Things (NB-IoT) technology has transformed this field. NB-IoT enables efficient real-time data collection and analysis, ensuring early detection and rapid response to geotechnical challenges. Explore the significance of NB-IoT in safeguarding communities and infrastructure from natural terrain instability threats.

Introduction to Vibration Control Curve in Industrial Plants

The Vibration Control (VC) curve is a vital tool used in the analysis of vibration-sensitive instruments, particularly in industrial settings. It represents the vibration response of instruments or machinery across different frequencies. By plotting vibration amplitude against frequency, engineers and researchers can understand how different components within a system respond to varying frequencies of vibration. This information is critical for ensuring the proper functioning and longevity of sensitive equipment.

In summary, the VC curve and the broader practice of monitoring industrial plant vibrations are indispensable for maintaining efficient, safe, and reliable operations. Through continuous monitoring and analysis, industries can prevent disruptions, enhance productivity, save costs, and ensure the safety of both equipment and personnel.
