• Electric vehicle (EV) test bench • High frequency applications • Power measurement and power analysis • Precision drives • Battery testing and evaluation systems • Wide bandgap (WBG) SiC and GaN devices • Current calibration Features • 500 A rms nominal current • 2V output at 500 A through BNC connector • 24/30 mm aperture with/without plastic insert • Dedicated power supply included High precision wide bandwidth DC current transducer (DCCT) measuring up to 750 A currents and continuously measuring 500 A currents with a linearity error less than 15 ppm. Using a special high frequency transducer head, the DW500UB-2V has a very wide bandwidth up to 10 MHz. Phase compensation is made easy thanks to a near constant phase delay of around 12.5 ns, including a 2m coax cable. Based on the ultra stable Danisense closed loop flux gate technology, the DW500UB-2V has very low offset and ultra low drift. Built in a compact aluminium housing, it provides high resolution for precise monitoring, reliable and consistent performance, and a rugged design for durability.

Linearity error Linearity error is defined as the deviation from a straight line. The straight line is a linear regression trend line based on the least squares method of the measurement points from 0 to positive max current and another trendline is calculated from 0 to negative max current. The difference between each measured point and the linear trend line is the linearity error. The linearity error eL can be expressed as (1), where Ireading is the measurement result and Ifitted is the regression value. Reading is the actual value measured at a given time. Full scale is the rated nominal value...

A When using REINFORCED insulated wire, all wiring must be insulated for the highest voltage used. When using BASIC insulated or uninsulated wire, follow the specified voltages in the table below: Connections: Mains AC cable and BNC connector Cleaning: The transducer should only be cleaned with a damp cloth. No detergent or chemicals should be used. All information subject to change without notice www.danisense.com

When multiple primary turns are used or high primary currents are applied the temperature around the transducer will increase, please monitor to ensure that the maximum ratings are not exceeded. It is recommended to have minimum 1 mm2 per ampere in the primary bus bar. Transducer Connection - Control Cable Connect the control cable to the circular connector on the front of Mains Connection via C7 Cable Use the supplied mains cable to connect mains power to the control box. The control box is designed for using universal mains 100-240Vac, 50-60Hz. The product is designed as a Class II product,...

DW500UB-2V Status LED The Status LED is indicated with this symbol For a typical RG58 cable, the signal velocity is around v = 198 · . When the LED is ON (green light) it means that the cable to the transducer is connected, and the unit is ready for measurements. If the LED is OFF (no green • The cable from the transducer to the control box might not be connected • The current is out of the measurement range • Current have been applied to the busbar before powering the unit • An internal error has occurred Control Cable It is important that the 3m cable from the transducer must be connected to...
