IP67, excellent waterproof performance, works well even under water condition 3 days.
CT power supply (induction power supply), is a device that uses CT installed on power lines to obtain power through electromagnetic induction principle. It consists of two parts: the power supply CT (energy transformer) and the power conversion module (converting the electrical energy obtained by CT into the required DC voltage). Our Energy Harvesting current transformer, IP68 design, hasas excellent waterproof performance and can work for a long time in outdoor water environments.
CT power supply (induction power supply), is a device that uses CT installed on power lines to obtain power through electromagnetic induction principle. It consists of two parts: the power supply CT (energy transformer) and the power conversion module (converting the electrical energy obtained by CT into the required DC voltage). Our Power Conversion Module has intelligent power management based on energy harvesting, with conversion efficiency ≥90%, IP68 design perfect for outdoor application.
The inductive Power Supply Current Transformers usually installed outdoors or in underground cable trenches and tunnels, with the working environment maybe raining, moisture, water accumulation. Once the split core CT with poor structure, the core cutting surface will be easy to rust, which affects the power supply ability, increasing working noise, even can't work. After long time R&D, our Coilcore's latest inductive Power Supply Current Transformers reach IP68 standard, which can achieve zero noise operation.
High saturate induction reduce volume of transformers, popular in inverter power application.
High Saturation Flux Density amorphous C Cutting Core, standard AMCC series and OEM size design supportted, popular in PFC Choke coils.
This is an isolation transformer that separates primary and secondary... In another word, it's full isolation transformer,not an autotransformer.
High accuracy nanocrystalline cores, for low voltage instrument current transformer, medium voltage instrument current transformer, high voltage instrument current transformer in industry application.
