Overview
Overview

The CT-BOX is a stand-alone system designed to measure with high accuracy and high precision DC and AC currents, providing the readings in different digital formats.

The CT-BOX system is developed to be used with the 0-FLUCS current-output DCCTs allowing measurements of currents up to kA.

The system integrates a burden resistor and a conditioning network feeding a 24-bit temperature stabilized ADC in order to have less than 1 ppm/K temperature dependance. The digital section interfaced to the ADC performs a calibrated measurement in order to eliminate the non-ideal behavior thus providing a 0.005% Full-scale current value accuracy. The ADC sampling frequency can be configured up to 100 kHz allowing thus to acquire high frequency components and fast current transients.

Current readings can be triggered in different modes:
- by an external LVTTL or TTL signal (hard trigger);
- by a remote command sent to the digital interface (soft trigger);
- internally, setting the sampling period and the acquisition window (mixed trigger).

The time-stamp, the current readings and the external temperature values are stored in a microSD Flash memory allowing long-term acquisitions.

The extremely compact design (1U - 9") allows using the instrument as benchmark or to install two complete systems in a 1U - 19" rack with the available mounting brackets.

The microSD memory can be either read via Ethernet, USB or RS-232 interfaces or removed from the system and transferred to other devices in order to download its content.

A temperature probe can be plugged on the back of the the system if needed in order to also read and store external temperature values.

A local display showing current and readings as well as other settings is present. A configurable alarm output can be used to signal to an external device if a pre-set current threshold has been exceeded.
An integrated Auto-Zero function allows to compensate for measurement setup offset currents.

The unit integrates a low-noise AC/DC power supply to connect the CT-BOX directly to the AC mains.

CT-BOX VIEWER free software application dedicated to current measurements: monitoring made easy with a single environment!

The CT-BOX VIEWER free software application allows controlling several different CT-BOXes at the same time, acquiring and plotting current and temperature readings using the Ethernet or the USB interface.

The CT-BOX VIEWER represents the perfect tool to quickly analyze real-time data or to save acquisition information and post-process them in different off-line environments (e.g. Matlab, Excel, etc.).
