High Voltage Differential Probes

High voltage differential probes utilize high attenuation and matched differential inputs to measure high voltages with very reasonable CMRR performance. These probes are rated for 1, 2, or 6 kV common-mode operation with wide differential voltage swings - ideal for power electronics circuits. They are optimized for measuring HV signals such as 50/60 Hz AC Line inputs and power electronics DC Bus/Link voltages, PWM Bridge/Drive outputs, DC-DC converter inputs/outputs, high frequency step-up/down transformer voltages, and inductor, capacitor and snubber diode voltages. In some cases, they may also provide reasonable performance for measuring gate-drive voltages and low voltage sensor voltages.
