VT1005
VT1005
AC/DC High Voltage Divider
Safely measure high Voltages up to 5000 V
Detect Efficiency Improvement Effects on the Order of 0.1%
Inverters used in rail and power system applications convert high-voltage power. To measure the efficiency of such conversions, it’s necessary to measure voltages of 1000 V and above. The VT1005 divides voltages of up to 5000 V and outputs them to a power analyser. In order to measure the efficiency of high-efficiency inverters with a high degree of precision, you need to be able to accurately measure power from DC to high frequencies. Thanks to its excellent frequency flatness, the VT1005 makes possible accurate measurement at frequencies ranging from the fundamental wave to switching-frequency components.
