In a DC power supply system, the normal operating current can reach tens or even hundreds of amperes. Yet, when it comes to leakage current monitoring, the anomalous current that actually requires attention may be as small as a few milliamperes.This is precisely the scenario where CHIPSENSE current......

With the ongoing development of sectors such as AI data centers, new energy storage, high-power charging, and smart microgrids, power systems are rapidly evolving toward greater efficiency, digitalization, and increased reliance on power electronics. These emerging power supply architectures demand...... READ MORE

When a variable frequency drive (VFD) employs vector control for a three-phase motor, it requires real-time knowledge of the motor's phase currents. However, a look at the hardware design documentation for many general-purpose VFDs reveals a seemingly counterintuitive detail: in some configurations,...... READ MORE

On October 20, a globally advanced provider of digital energy and critical infrastructure solutionsissued a price adjustment notice to its channel partners, announcing an increase of 3% to 8% in the list prices for UPS systems, precision air conditioning units, DC power systems, and medium-voltage v......

In an energy storage converter, the charge-discharge cycle switches dozens of times a day, causing the current to repeatedly cross zero. Why does this specific measurement point pose the ultimate test for a sensor’s "zero-return" (or zero-point recovery) capability?On the DC input side of a photovol...... READ MORE

A string-type photovoltaic (PV) inverter may appear to be nothing more than a metal enclosure from the outside, yet internally, it must manage direct current (DC) power arriving from various PV strings. Factors such as fluctuations in sunlight, changes in module temperature, and localized shading ca...... READ MORE

In the factory, a fan suddenly stopped.Maintenance personnel inspected the motor but found no obvious abnormalities in the wingdings, they also checked the mechanical components, finding that the fan was not jammed. Yet, the fault log of the variable-frequency drive (VFD) clearly showed an over-curr...... READ MORE

Come to think of it, electric welding is perhaps the trade in industrial manufacturing that relies most heavily on experience.Veteran welders often judge current stability with their own eyes—observing the steadiness of the arc, the amount of spatter, and the quality of the weld bead formation. This...... READ MORE

AR4V P00 SERIES Open-loop Hall current sensorAR4V P00 series consists of open-loop current sensors based on the Hall effect principle. They are designed to measure DC, AC, and pulsed currents, providing electrical isolation between the primary andsecondary circuits. Powered by a singl...... READ MORE

A 200MW/400MWh shared energy storage power station has officially been connected to the grid in Xingning, Meizhou.According to public reports, the facility is equipped with 80 energy storage battery units—each with a capacity of 5MWh—and represents a total investment of approximately 480 million yua......

In factory workshops, freight yards, and construction sites, one of the most common pieces of equipment is the overhead crane—also known as a bridge crane. It travels along overhead rails, lifting and horizontally moving heavy loads—such as tons of steel coils or structural components—to designated...... READ MORE

At midday, when the sunlight is strongest, the village's voltage actually spikes—a phenomenon driven by the proliferation of distributed photovoltaic systems. This raises a critical question: what specific parameters should be monitored at this voltage measurement point within the distribution netwo...... READ MORE

Recently, the Department of Industry and Information Technology of Guangdong Province issued a notice announcing the list of "Innovative SMEs" for 2026 and those that have successfully passed the re-evaluation; Zhuhai CHIPSENSE was successfully included in the list of Guangdong Province's Innovative......
