The high precision DC current transducer (DCCT) is capable of measuring currents up to 1500A, with continuous measurement of 1000A. This is with a linearity error of less than 1ppm, says the company. An over-range capability of 1200A RMS for up to 30 minutes is also supported.
Features
The DN1000ID-CP02 features an increased creepage and clearance distance of 38mm, compared with 11mm for the standard DN1000ID version.
Also, the permissible voltage for uninsulated cables has been raised from 1000V to 3200V, highlights Danisense.
Note also, the DN1000ID-CP02 incorporates a removable isolation insert and a large 40mm aperture to accommodate wide cable terminals.
DN1000ID-CP02 specification

It is based on the Danisense closed loop flux gate technology, which meands the DN1000ID-CP02 has very low offset and ultra low drift, says the company. In terms of noise, there is sub-ppm rms noise in the frequency range up to 10 kHz.

Applications
As system voltages continue to rise across a range of applications, the features makes the device suited for power measurement and power analysis in EV chargers, power inverters, and battery energy storage systems, says the Danish company.
Other possible applications, include EV test benches, particle accelerators and MRI systems. Also medical scanners, battery testing and evaluation equipment, and current calibration systems. Basically, all precision current-sensing applications.
