Description
About the DP-08VF 150MHz High Voltage Differential Probe
The DP‑08VF 800 V 150 MHz high‑frequency differential voltage probe is an essential accessory for engineers working with power electronics and high‑voltage systems. It enables isolated, floating and safe measurements using any oscilloscope, DAQ or data recorder, allowing the test instrument to remain properly grounded while the input signals operate at elevated or floating potentials.
Designed for demanding applications, the DP‑08VF allows accurate differential and floating measurements across a wide range of AC power systems including 460V/230V/110V AC inputs as well as chopped and switching power supplies, thyristor controllers, variable‑speed motor drives (PWM signals), motor inrush currents and current‑shunt voltage measurements. Its isolated input stage uses two 4mm safety banana sockets ensuring secure high‑voltage connections while the BNC output provides simple universal compatibility with oscilloscopes and data acquisition equipment.
The DP‑08VF can be powered by either a battery or an external power supply, making it suitable for both bench and field use. With its combination of high bandwidth, high voltage capability, and robust isolation. it delivers clean and reliable waveform capture in even the most challenging high‑frequency power‑electronics environments.
