1、 Product Features

Adopting the principle of capacitive voltage division, it has high accuracy, good linearity, and wide frequency band

● Small size, light weight, low power consumption, suitable for placement inZW20/ZW28SwitchedSF6In the air chamber

There is no ferromagnetic saturation or ferromagnetic resonance

● Primary and secondary isolation, safe and reliable

Low output voltage, no risk of secondary short circuit and high current

● Wide temperature range（-40℃～70℃）

● High insulation impedance (>)1000MΩ）

There is no interface layering issue, safe and reliable

● Strong load capacity（1MΩ), the cable length can reach15rice

Three in one cable output signal, easy to connect
