Description
About the DP-100 Oscilloscope Differential Voltage Probe
The DP100 differential voltage probes are an essential accessory for engineers working in power electronics, high‑voltage systems, and industrial energy‑conversion applications. Designed for safe, accurate and isolated measurements, the DP100 enables reliable oscilloscope observation of high‑potential signals while keeping the oscilloscope securely grounded—making it indispensable for environments where standard single‑ended probes cannot be used.
The DP100 differential voltage probes are an important accessory for any application involved in power electronics and high voltage systems. These probes allow isolated and floating measurements with any oscilloscope or data recorder, allowing the oscilloscope to remain grounded. Using a DP100 differential probe, differential and floating (isolated) measurements can be made on a variety of AC power systems like 460V/230V/110V AC input power supplies, chopped and switching power supplies, thyristor controllers, variable‑speed motor drives (PWM signals), motor inrush current and measurement across current shunts.
Engineered for versatility and safety, the DP100 features isolated inputs via two 4mm safety banana sockets, ensuring secure and reliable connection to high‑voltage test points. The BNC output provides effortless compatibility with oscilloscopes and DAQ systems, enabling clean, stable waveform capture across a wide range of power‑electronics environments.
The DP isolation probes are powered from a battery or an external power supply, offering flexibility for both bench and field use. With strong common‑mode noise rejection, high input impedance and robust insulation The DP100 delivers accurate differential measurements even in noisy, high‑EMI switching environments.
Ideal for R&D labs, industrial maintenance teams, academic programs and system validation engineers. The DP100 is the go‑to solution for safe floating measurements, high‑voltage differential accuracy and reliable oscilloscope performance in demanding power‑electronics applications. Its combination of safety, measurement fidelity and broad application coverage makes it a trusted tool for modern high‑voltage diagnostics.
