Main Features

AC/DC CURRENT MEASUREMENT: Dewesoft offers high-accuracy zero-flux current transducers, Rogowski coils, current clamps, and shunts for AC and DC current measurement.
HIGH ACCURACY: Highly precise zero flux current transducers or fluxgate compensated clamps are a perfect fit for most demanding power measurements for E-mobility and electric motor and inverter testing applications.
UP TO 30 000 AMPS: We offer a very wide range of current measurement ranges up to 30 000 (30 thousand) amps.
-40°C to +85°C: Our current transducers can operate in a wide temperature range. This is ideal for winter (-40°C) or summer climate testing (+85°C).
INTEGRATED SENSOR POWER SUPPLY: Current clamps and zero-flux transducer can be powered straight from the amplifiers of our data acquisition devices like S IRIUS, SIRIUS XHS, R2DB, R8, or KRYPTON.
FLEXIBLE: There are more than 1000 different current sensors are available on the market. If you want to connect your own current sensors we are very happy to help you here. Dewesoft DAQ systems allow connecting any type of current transducers.

Zero-flux Transducers

Dewesoft IT series of zero-flux transducers offer highly precise current measurements with linearity below 0.002% ranging from 60 A to 1000 A RMS, featuring up to 800 kHz bandwidth which makes them perfect for E-Mobility and inverter motor measurements.

Use integrated Dewesoft SIRIUS PWR-MCTS2 power supply for powering these current transducers directly from Dewesoft instruments without any external power supply.

Please see the full technical specification for more details.

AC/DC Current Clamps

The DS-CLAMP-xxDC series offers DC and AC current measurements from 200 A to 1800A pk range using flux gate or hall sensor technologies with accuracy down to 0.3 % and bandwidth up to 500 kHz.

The DS-CLAMP-xxAC series offers basic AC current measurements from 5 A to 1000A range using iron core technology with accuracy down to 0.15 % and bandwidth up to 10 kHz.

Please see the full technical specification for more details.

Rogowsky Coils

Rogowsky coils

Rogowsky coils are easy to install and therefore perfect for field measurements.

A wide variety of ranges are available from 3 A to 30000 A with accuracies down to 0.1 %. The bandwidth is starting from 10 Hz and is ending at 1 MHz.

Please see the full technical specification for more details.

DSI Current Shunt Adapters

While some amplifiers offer direct measurements of small range current inputs. Dewesoft offers external 20 mA, 5 A, isolated 10 A and isolated 20 A shunts with accuracy down to 0.1% for direct AC or DC current measurements. See DSI adapters product page for shunt adapter details.

Isolated voltage input amplifiers are required for connecting shunt resistor adapters.

Integrated power supply

All current sensors that require an additional power supply we offer integrated power supply option - SIRIUS PWR-MCTS2. With this option no external power supply needed.

SIRIUS PWR-MCTS2 is a power supply unit for powering these current transducers directly from Dewesoft instruments without any external power supply. SIRIUS PWR-MCTS2 can be built into SIRIUS compatible chassis or directly into R1DB/R2DB, R4 or R8 data acquisition system.

E-mobility Power Measurement Device With Integrated DC-CT Current Transducer

The SIRIUS XHS 1xHV, 1xHA is a completely new DAQ device and is well suited for in-vehicle electric power measurements. It features an integrated patented DC-CT current transducer that allows very precise current measurements even in the most demanding applications such as very high current peaks as well as the leakage current measurement.

The current transducer uses special patented fluxgate technology in the null method. Compared to Hall and standard Flux-gate transducers, the core is without air gap and designed in a way that electronics can compensate and maintain zero balance in the core. In the end, this results in better sensitivity, immunity to external magnetic fields, low offsets, and linearity.

The device can also measure voltage 2000V peak (CAT II 1000V) with up to 5 MHz bandwidth.

The device is small and perfect for the installation directly into a vehicle in the power lines. It offers an IP65 degree of protection which allows the usage in harsh environments and during rough drives.
