Hioki AC/DC HIGH VOLTAGE DIVIDER VT1005

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.

Key Features
• Max. Input 5000 V (*1) - 2000 V CAT II / 1500 V CAT III
• Measurement Accuracy: ±0.08% (DC) / ±0.04% (50/60 Hz) / ±0.17% (50 kHz)
• Frequency Flatness: ±0.1% Amplitude Band 200 kHz Typ. / ±0.1° Phase Band 500 kHz Typ. (*2)
• Measurement Band: DC to 4 MHz (-3 dB)
• Noise Resistance: CMRR 80 dB Typ. (100 kHz) / Differential Input Method
