Product Introduction

       The NDFHX-103UI series Current and Voltage Transformer Load Box is specifically designed to provide various effective loads for testing current and voltage transformers, making it an ideal supporting product for various transformer verification devices. This product is strictly designed in accordance with the national standard JJG 314-2010 "Verification Regulation for Measuring Voltage Transformers". It features a large output capacity, comprehensive load types, light weight, attractive appearance, and strong stability.

Product Features

☆、Equipped with light indicators for clear gear display. Automatic refresh upon startup, with a reasonably designed manual/automatic switch button. When connected to the main unit, it is generally set to automatic mode; when manual selection is needed, switch to manual mode. Voltage gears, like current gears, have light indicators for each gear.
☆、To ensure stable accuracy of instrument error, over 90% of internal components are imported brands, ensuring customer satisfaction and reducing equipment failure rates.
☆、Fully electronic load box with automatic load point switching. Whether for current or voltage loads, a single command automatically switches the internal load to real load, unlike simulated or virtual loads used by other manufacturers.
☆、The load box uses printed circuit board design internally, reducing wiring and resistance while improving stability.
☆、The currently used volt-ampere value is displayed with lights, making it highly visible.
☆、Automatic refresh upon startup, automatic detection of load for each gear, with an aesthetically designed interface and user-friendly operation.
☆、The overall design concept and level are superior to most load boxes domestically.
