AC/DC HIGH VOLTAGE DIVIDER VT1005 Power Efficiency Measurement at 1000 V and Above Safely Measure High Voltages up to 5000 V 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 analyzer. - Max. Input 5000 V *1, 2000 V CAT II , 1500 V CAT III *1: ±7100 Vpeak, no measurement category, anticipated transient overvoltage of 0 V Stable Efficiency Measurements Down to the Decimal Point 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. - Measurement Accuracy: ±0.08% (DC), ±0.04% (50/60 Hz), ±0.17% (50 kHz) - Frequency Flatness: ±0.1% Amplitude Band 200 kHz Typical, ±0.1° Phase Band 500 kHz Typical *2 - Measurement Band: DC to 4 MHz (-3 dB) - Noise Resistance: CMRR 80 dB Typical (100 kHz), Differential Input Method *2: After phase correction by the power an

Detect Efficiency Improvement Effects on the Order of 0.1% Measurement Accuracy: ±0.08% (DC), ±0.04% (50/60 Hz), ±0.17% (50 kHz) Frequency Flatness: ±0.1% Amplitude Band 200 kHz Typical, ±0.1° Phase Band 500 kHz Typical *1 The VT1005 can measure voltage with excellent accuracy across a broad band of frequencies. Accuracy is 0.1% or less at DC and commercial frequencies (50/60 Hz). In addition, the device can measure the most commonly used switching frequencies (10 kHz or less) and the switching frequencies of inverters that use SiC power devices (from 10 kHz to 50 kHz) with a high degree of...
