SINOMAGS STK-HD/KG1
100 ns & 2 MHz
High-Frequency On-boardCurrent Sensor Module
Officially Launched!
Driven by the new energy revolution, power electronics upgrading, and accelerated industrial automation, the industry is rapidly entering a new era defined by 'high frequency, high efficiency, and large current."
As the "sensory nerve" of power electronic systems, current sensors’ response speed, bandwidth limit, and large-current measurement capability are core bottlenecks for equipment performance breakthroughs.
Following current sensor modules’ high-frequency trend, sinomags launched STK-HD/KG1 (high-frequency, large-current sensor module). With 100 ns ultra-fast response, 2 MHz ultra-wide bandwidth, and 150 A ultra-large range, it redefines the precision boundary of high-frequency current measurement.
With inherent strengths (high sensitivity, low power, wide temperature range), TMR technology is the mainstream for high-frequency current measurement.
STK-HD/KG1 aligns with this trend. Building on basic models’ strengths (high isolation, precision, low power), it upgrades key performances to meet industry demands for high-frequency, large-current modules, offering a more efficient solution for high-frequency precise measurement.
