DP-30k High Voltage Differential Probe

See more Differential Voltage probes

The DP-30K differential voltage probes are an important accessory for any application involved in power electronics and high voltage systems. These probes allow isolated and floating measurments with any DAQ, oscilloscope or data recorder, allowing the oscilloscope to remain grounded. Using a DP-30K 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. The isolated input is made via two 4mm/banana safety sockets. The BNC output allows easy connection to an oscilloscope or DAQ. The DP isolation probes are powered from a battery or power supply.
