With our DC-CT Sensor battery charging and discharging currents are monitored very accurately due to a low offset, below 10 mA, and at high accuracy of 0.1% to offer excellent continuous state of charge determination.
With over 1 MHz bandwidth, low noise below 1 mArms and high accuracy of 0.1% the DC-CT offers high acceleration, smooth (low-ripple) low-speed, high-speed operation with accurate positioning.
The DC-CT high accuracy shortens battery charging times, and due to its high accuracy over wide temperature range makes DC-CT the best current sensor for use in charging stations, energy metering and billing systems.
The DC-CT provides the most cost effective solution for leakage current measurement in DC/AC systems. It is due to a galvanically isolated design, excellent immunity to external DC/AC magnetic fields, and precision better than 500 μA.
The all in one solution, simple use, makes DC-CT a Plug & Play high accuracy sensor component for use in Switching Power Supplies. Voltage output, high immunity allows compact placement next to power chokes, minimizing total PCB dimension.
The DC-CT excellent stability and accuracy help you analyzing photo-voltaic power generation, early detection of performance degradation, with aim to improve system performance and ROI.
Wide temperature operation from -40°C to over 140°C, and high sensitivity of 5 mGauss.
Flexible DC-CT solutions support the state-of-the-art power supplies in synchrotrons, variable inductance chokes and magnetic field sensing.
The core of the DC-CT technology relies on the principle of measuring a DC component in a closed-loop core. A DC flux path is modulated in a small region only by a new type of magnetic component called a magnetic switch.

A single core operates in a zero-flux mode, in which a secondary compensation winding mirrors the primary current for a ratio proportional to the number of secondary turns yielding gain accuracy of 0.1% and below.
A closed-loop gap-less core with very high permeability directly brings a very high sensitivity of less than 0.5 mA and 100 A range. Ferromagnetic materials in addition offer wide bandwidths over one MHz and at rated current.
The DC sensing principle is temperature independent and yields offsets below 0.1% RR over entire temperature range. Due to its locality it generates negligible noise under 1 mA_rms. The residual core remanences that may generate magnetic offset are removed by degaussing the gap-less core toless than 10 mA.
