Product Introduction

Performance characteristics of high voltage current clamp series products：
1.The unique automatic plug-in clamp structure is particularly suitable for on-line current testing of high-voltage overhead lines.
2.Using permalloy iron core, it has stable performance and high precision, strong anti-interference ability, and is suitable for complex interference environments.
3.Can output current signal or voltage signal.
4.The battery compartment can hold 4 1.5V AAA alkaline dry batteries to provide power for secondary development.
5.With insulating rod interface: M24 screw teeth.
6.The range, variable ratio, output interface, etc. of the transformer can be customized according to customer requirements.
7.Output interface: Terminal interface: BNC plug/4.0mm dual banana plug/3.5mm audio plug/bare wire tap (optional), cable length 1.5m.
8.Safety level: CATⅢ600V.
9.Working temperature: -15°C～50°C
