NDFRC Series AC/DC Digital Voltage Divider

Product Introduction

         This product is an ideal device for high-voltage measurement, primarily used in power systems and electrical/electronic equipment manufacturing sectors to measure power-frequency AC high voltage and DC high voltage.

       The instrument consists of two parts: a high-voltage divider and a low-voltage display meter, which are connected using matching cables.

Product Features

☆、High Accuracy

      Utilizes precision high-voltage film capacitors and high-voltage glass glaze resistors, featuring high input impedance, reduced test current, low power consumption, and improved measurement accuracy and stability. The signal processing section employs high-performance operational amplifiers for signal amplification, adopts advanced dual-integration AD sampling technology, and uses a four-and-a-half-digit LCD display with a resolution of up to 0.001kV, making it an upgraded replacement for high-voltage electrostatic voltmeters.
☆、Excellent Anti-Interference Performance
        Employs special isolation technology. The aluminum alloy voltage equalizing ball has a smooth and glossy surface, effectively improving the electric field distribution around the ball, preventing corona discharge, and enhancing the anti-interference capability of measurement data. The low-voltage display meter adopts a fully enclosed metal structure for isolation, and the high-voltage divider and low-voltage display meter are connected using high-quality coaxial cables to minimize the impact of high voltage on readings, ensuring high stability and linearity.
☆、Safe and Reliable
       The instrument consists of a high-voltage divider and a low-voltage display meter. The high-voltage divider uses DuPont filling materials and is encapsulated with special processes, resulting in a more compact structure, lighter weight, minimized internal partial discharge, and higher reliability. There is no risk of oil leakage. During operation, the high-voltage divider and low-voltage meter are connected via coaxial cables, with a significant distance between high and low voltage sections, ensuring safe and reliable performance.
☆、Simple Operation
       Uses a dial switch to toggle between high/low voltage and AC/DC, providing convenience and speed. The four-and-a-half-digit LCD directly displays measurement results, making operation simple and intuitive. This greatly facilitates on-site testing work.
☆、Portable Design
       Features a portable structure, with the entire unit housed in an aluminum alloy case for easy assembly and disassembly. Compact size, lightweight, and easy to carry, making it highly convenient to use.
