2.3.2.1.2 Version with calibration winding For some applications, it’s preferable to perform a prior functional / accuracy check of the device at full scale or a fraction of full scale before apllying the power. For that purpose, a primary winding, most commonly of 100 turns or 1000 turns is added.
For –15VDC, I output = Ins + Is = 96 + 600 = 696mA 2.3.3.2 Multi-channels power supplies interface DSSIU series Danisense recommends the 1U rack-mount multi-channels power supplies interface DSSIU series for best performances, many useful features and options. The following table shows the different options:...
DSSIU-4-1U DSSIU-6-1U DSSIU-6-1U-V Mains voltage DSUB9 connector for transducer connection Banana jacks for transducer’s current output Banana jacks for calibration winding terminals Status connector Mini XLR socket for transducer’s voltage or current outputs 2.3.3.3 Connection of calibration winding with DSSIU-6-1U (or DSSIU-6-1U-V) When a device with calibration winding type - CD[n turns] is connected to the DSSIU-6-1U using the optional DSUB cable, the terminals of the calibration winding are accessible via the yellow banana sockets at the back panel of the DSSIU-6-1U (or DSSIU-6-1U-V).
2.3.3.4 Voltage Output Modules (VOM) A voltage output module (VOM) is a PCBA containing a low drift, precision measurement resistor ) and a signal conditioning circuit which allow conversion of the device’s rated nominal current output to a 1V or 10V voltage signal. Up to 6 VOMs can be factory mounted into the 6-channel power supplies interface unit (DSSIU-6-1U-V).
2.3.3.6 Noises immunity of voltage output versions Compared to current output devices, voltage output models are generally less immuned to induced noises from external sources. In the following schematics, two configurations are shown. Config. 1: Current transducers with voltage output (e.g. DS600UB-1V) BNC cable DS600UB-1V DSUB cable...

4 . ELECTRICAL CONSIDERATIONS 4.1 Common mode noises Common mode noises occur when high dV/dt in switching circuits such as inverters, switch mode power supplies etc. generates parasitic currents i circulating through stray capacitance Cs that exists between the parts of an electronic component or circuit simply because of their proximity to each other. The value of ip is determined by the following formula: = Cs x dV/dt Sensing Head...
- a primary current flows in the hole of the un-powered device etc. When saturation occurs, the DS series is designed to hold the output signal high for a period up to 1 sec- ond as shown in the green color waveform below. During that period, if the overload disappears, the DS oper- ates normally.
4.3 Influence of the return conductor The magnetic field from the return branch of the primary current (cable / busbar) or of any adjacent conductors (e.g. the remaining phases of a 3 phase configuration) exerts a certain influence on the sens- ing core of a fluxgate current transducer (grey area of the illustration below).
7.5Ω 4.5 Frequency derating Danisense fluxgate current transducers offer extreme precision in DC and low frequency. However, they also have excellent frequency bandwidth relative to similar products in the market thanks to fast switching speed of the fluxgate excitation circuit. High frequency AC current produces heat in the magnet- ic core.
Consideration must be given to the value of the measuring resistor R to avoid saturation. Please consult with Danisense or your nearest local Danisense’s representative for advice. 4.7 Measuring small currents with multiple primary turns Danisense’s ultra-stable and high precision fluxgate current transducers exhibit excellent linearity error (less than a few ppm), one of the best few available in the market.
