ST1005 – Impulse High Voltage Divider
Overview
Versatile, Wideband Voltage Measurement from DC to Surge PD and Beyond – ST1005 is a high-accuracy voltage divider that converts high-voltage signals—up to 5 kV rms/7.1 kVpeak—at a 1000:1 ratio. With excellent frequency characteristics from DC to 10 MHz (–3 dB), it delivers a flat response across a wide frequency range. This makes it ideal not only for accurate voltage measurements and waveform observation at surge PD testing, but also for a wide variety of other high-voltage applications.
Key Features
- Divides up to 5 kV rms/7.1 kVpeak input voltage at a 1000:1 ratio
- Wideband frequency response: DC to 10 MHz (–3 dB)
- High-accuracy voltage conversion: ±0.3% f.s. measurement accuracy (DC, 45 Hz to 66 Hz)
