SYSTEME DE MESURE DE COURANT - / CAENels
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 dependence. 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.
