The GY Automatic Power-Frequency Withstand Voltage Control Console is a fully automated control console for performing power-frequency dielectric/withstand voltage tests on electrical products, components and insulation materials to assess insulation integrity and overvoltage tolerance. It is designed for production lines, QC and test laboratories and provides touch-driven operation, active safety monitoring, audible/visual alarms, integrated printing and USB data export, plus hardware/software anti-interference for stable field performance.

Key features

• 7" high-resolution touch interface with bright 800×480 full-color PLC screen displaying voltage, current, time, status and prompts in a unified view.
• Touch-driven operation: high-precision touchscreen for direct parameter entry and function control.
• Windows XP OS with streamlined interface for common test scenarios.
• Password-protected digital calibration replacing analog potentiometers for accurate field adjustment.
• Programmable VT (transformer) ratio with password protection to support multi-voltage transformers from a single console.
• Guided workflow and status prompts enabling operation without consulting manuals.
• Active safety monitoring with real-time "Test-in-Progress" display and continuous operator alerts.
• Audible and visual alarm system for test abnormalities.
• Auto-timing & zero-return (STOPWATCH mode): automatic timing at target voltage, results display and automatic zero reset.
• Manual voltage ramp via step buttons with auto-limit detection and overvoltage protection.
• Intelligent ramp control: automatic reduction of boost rate at 90% of target voltage to ensure voltage accuracy.
• Customizable ramp/boost speed for optimal transformer matching.
• Anti-interference design combining hardware and software noise suppression for EMI environments.
• Integrated printing for immediate hardcopy of test data, date and parameters; USB export for long-term archival.

Typical applications

• Production and end-of-line dielectric testing.
• Incoming inspection of electrical components and insulation materials.
• Quality control and conformity verification for product safety.
• R&D and laboratory endurance testing.
