Wiseman V8 Ripple Test System for High-Voltage DC Power Supplies (5 kV – 65 kV)

Overview

The Wiseman V8 Ripple Test System is a precision-engineered diagnostic instrument designed exclusively for quantitative measurement and analysis of residual AC ripple superimposed on high-voltage DC power supplies. Operating across a calibrated output range of 5 kV to 65 kV DC, the V8 system employs a high-bandwidth, galvanically isolated differential measurement architecture optimized for low-noise signal acquisition under high-potential conditions. Unlike generic oscilloscope-based approaches, the V8 integrates proprietary high-voltage probe compensation, real-time RMS/peak-to-peak ripple computation, and temperature-stable voltage divider networks traceable to NIST-equivalent national metrology standards. It is engineered for use in environments where regulatory compliance, long-term measurement repeatability, and electromagnetic compatibility (EMC) integrity are critical—particularly in analytical instrumentation requiring ultra-stable bias voltages, such as time-of-flight mass spectrometers (TOF-MS), electron multipliers, and electrostatic lens systems.

Key Features

• DC voltage range: 5 kV to 65 kV continuous, with ±0.5% full-scale accuracy at 23 °C ±2 °C
• Measurement bandwidth: DC to 10 MHz (–3 dB), supporting detection of switching-frequency harmonics from resonant DC-DC converters
• Ripple resolution: ≤10 mV_p-p (at 30 kV), with auto-ranging analog front-end and 16-bit ADC sampling at 100 MS/s
• Galvanic isolation: 100 kV_DC reinforced insulation between measurement input and user interface ground
• Integrated thermal drift compensation: Active sensor calibration over operating temperature range (0 °C to 40 °C)
• Compliant with IEC 61000-4-8 (power frequency magnetic field immunity) and IEC 61326-1 (EMC for laboratory equipment)

Sample Compatibility & Compliance

The V8 system is purpose-built for evaluating DC high-voltage sources used in regulated analytical platforms—including but not limited to mass spectrometry (per ASTM E1598, ISO/IEC 17025-accredited labs), X-ray fluorescence (XRF) tube biasing, and accelerator-based ion source characterization. Its input interface supports standard SHV and MHV coaxial connectors, enabling direct connection to OEM HV modules without external attenuation or signal conditioning. All internal high-voltage components comply with UL 61010-1 and IEC 61010-1 safety requirements for measurement category CAT III 65 kV. The device meets RoHS 3 and REACH substance restrictions and carries CE marking under the EU Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU).

Software & Data Management

The V8 includes Windows-compatible PC software with configurable acquisition parameters, real-time spectral analysis (FFT up to 16k points), and automated report generation compliant with GLP/GMP documentation workflows. Data export supports CSV, MATLAB (.mat), and XML formats; metadata fields include timestamp, ambient temperature, operator ID, and instrument serial number. Audit trail functionality satisfies FDA 21 CFR Part 11 requirements when deployed with validated IT infrastructure—supporting electronic signatures, user access levels, and immutable record retention. Firmware updates are delivered via signed binary packages with SHA-256 verification.

Applications

• Verification of ripple performance in OEM high-voltage modules for TOF-MS and quadrupole mass analyzers
• Pre-shipment validation of HV power supplies prior to integration into medical X-ray imaging systems (IEC 62304 Class B)
• Troubleshooting electromagnetic interference (EMI) coupling paths in vacuum chamber bias networks
• Long-term stability monitoring of HV sources in semiconductor wafer inspection tools
• Supporting ISO/IEC 17025 clause 5.9.1 (method validation) for in-house HV supply qualification protocols

FAQ

What is the maximum measurable ripple frequency supported by the V8 system?

The system supports full-amplitude measurement up to 10 MHz (–3 dB point); harmonics beyond this are attenuated per its anti-aliasing filter response.
Can the V8 be used with pulsed DC high-voltage sources?

Yes—its acquisition engine captures transient ripple events with pulse widths ≥100 ns; trigger synchronization is available via TTL input.
Does the V8 require annual recalibration?

Wiseman recommends traceable recalibration every 12 months using NIST-traceable HV reference standards; certificate includes uncertainty budget per ISO/IEC 17025.
Is remote operation supported over Ethernet or USB?

Standard communication is via USB 2.0 (CDC class); optional Ethernet module (IEEE 802.3, TCP/IP) enables integration into SCADA or LabVIEW-based test benches.
How does the V8 handle grounding conflicts in floating HV systems?

Its fully isolated measurement path eliminates ground loops; common-mode rejection ratio exceeds 120 dB at 1 kHz, verified per IEC 60687.
