PKDV5000 Series High-Voltage Differential Probes: The New Standard for Safe, Precise, and Efficient Measurement

High-Performance Signal Fidelity for Demanding Power Electronics Applications

The PRBTEK PKDV5000 series of high-voltage differential probes is engineered for superior performance in the fast-paced field of power electronics. Offering outstanding signal fidelity and precision, these probes are essential tools for the design, debugging, and maintenance of switching power supplies, frequency converters, motor drives, and other high-power systems. With bandwidths extending up to 500MHz and maximum voltage capabilities up to 8000Vpk, the PKDV5000 series provides accurate and reliable floating measurements for a vast range of applications.

Key Features:

• Exceptional Bandwidth & Fast Rise Time: With models offering up to 500MHz bandwidth and rise times as fast as <700ps, the PKDV5000 series captures high-speed signals with exceptional accuracy.  This ensures precise characterization of fast-switching power semiconductors.
• High-Voltage Floating Measurement Capability: Safely and accurately measure differential voltages on high-voltage circuits, with models supporting up to ±8000V (DC + peak AC). 
• Selectable Attenuation Ratios: Each probe features dual-range attenuation, providing optimized resolution and flexibility for measuring a wide spectrum of signal amplitudes. ³³³³
• Superior Signal Integrity: A high Common Mode Rejection Ratio (CMRR) across a wide frequency range (>80dB at DC, >50dB at 1MHz) and high input impedance (up to 48MΩ || 2.5pF) minimize circuit loading and ensure that the probe accurately measures the signal of interest while rejecting unwanted noise. 
• User-Centric Design:
  • 5MHz Bandwidth Limit: A selectable 5MHz filter effectively reduces high-frequency noise and interference, allowing for clearer measurements of fundamental switching frequencies. 
  • Over-Range Protection: Visual and audible alarms immediately notify the user if the input voltage exceeds the selected range, protecting both the probe and the device under test. The audible alarm can be disabled. 
  • Intuitive Controls: Simple, electronic push-button controls for range selection, bandwidth limiting, and alarm settings enhance durability and ease of use.
  • USB Power Interface: The modern Type-C USB port provides convenient and flexible powering options via the included 5V/2A adapter or any compatible USB source. 
• Universal Oscilloscope Compatibility: A standard BNC output interface ensures seamless connection to oscilloscopes from any manufacturer. The PKDV5005 series is optimized for 50Ω input impedance systems, while other series are designed for standard 1MΩ inputs. 

Applications:

• Switching Power Supply (SMPS) Design and Analysis
• Inverter, UPS, and Frequency Converter Development
• Motor Drive and Electric Vehicle (EV) Systems
• Variable Frequency Drive (VFD) Troubleshooting
• Power Semiconductor (IGBT, MOSFET, SiC, GaN) Characterization
• Ballast and LED Lighting Design
• General-purpose high-voltage, floating-signal measurements

Safety and Handling:

To ensure operator safety and measurement integrity, please adhere to the following guidelines:

• Voltage Limits: Never exceed the maximum specified input voltage for both differential and common-mode measurements. 
• Proper Sequencing: Always de-energize the circuit under test before connecting or disconnecting the probe inputs. 
• Grounding: Ensure the probe’s BNC output is securely connected to a properly grounded oscilloscope or measurement instrument. 
• Warm-up Period: For optimal accuracy, allow the probe to warm up for 20 minutes before performing critical measurements. 
• Input Leads: For best high-frequency performance and noise rejection, twist the input leads together. Avoid using extension leads, as they can degrade measurement quality.
