Description
About the DP-15k Oscilloscope Differential Voltage Probe
The DP‑15K differential voltage probes are a critical accessory for engineers working in power electronics, high‑voltage systems and industrial energy‑conversion applications. Designed to deliver safe, accurate and isolated measurements. The DP‑15K allows users to observe isolated and floating high‑potential signals with any oscilloscope or data recorder while keeping the oscilloscope securely grounded. This makes it indispensable for environments where standard single‑ended probes cannot be used due to grounding restrictions or elevated voltage levels.
The DP‑15K differential voltage probes are an important accessory for any application involved in power electronics and high voltage systems. Using a DP‑15K 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 safety and versatility, the DP‑15K features isolated inputs via two 4mm safety banana sockets, ensuring secure 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 DP‑15K 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 DP‑15K 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.
