IEC 62368-1 Annex D.1 Impulse Voltage Generator Test Equipment

Ensure the safety and compliance of your Audio/Video, Information, and Communication Technology equipment with our advanced Impulse Voltage Generator. Specifically designed to meet the rigorous requirements of IEC 62368-1 Annex D.1, this test solution simulates the effects of transient overvoltages (impulse spikes) on equipment insulation. By generating the standard 1.2/50 µs voltage impulse waveform, it allows manufacturers and test houses to verify product robustness and safety margins required for global market certification.

Key Features

• Standard Compliance: Fully adheres to the test parameters outlined in IEC 62368-1:2014 (Ed.3) and earlier revisions, Clause D.1.

• Precise Waveform Generation: Delivers the required 1.2/50 µs impulse voltage waveform with high accuracy, ensuring reliable and repeatable test results.

• High Voltage Output: Capable of generating impulses up to [Insert Max kV, e.g., 16kV] to cover mains and signal port testing requirements.

• User-Friendly Interface: Intuitive digital control panel for setting peak voltage, polarity (positive/negative), and number of pulses.

• Robust Safety Features: Equipped with high-voltage interlocks, emergency shut-off, and clear discharge indicators to ensure operator safety during testing.

• Compact Design: Space-saving benchtop or rack-mountable design suitable for R&D labs and quality control environments.

Applications

• Type testing of IT equipment (ITE) and power supplies.

• Verification of basic, double, and reinforced insulation.

• Compliance testing for CE, UL, and other international safety marks.

Important Safety Precautions

The impulse voltage generator generates high-voltage pulses during operation. For safety, please read this manual and use this equipment correctly. Please pay attention to the following points during use:

(1) Do not use this equipment when your hands are wet or the relative humidity exceeds 75%.

(2) Because there is a high-voltage pulse applied to the terminal (impulse out), please confirm that the high-voltage power supply is disconnected when you want to change the wiring (HV.POW light is off) before proceeding.

(3) The operation must strictly follow the instruction manual.

(4) Although electric shocks are rarely encountered when operating this equipment, for safety, do not eat during operation to prevent accidental obstruction of eating caused by electric shocks.

(5) This equipment uses a vacuum contactor to generate voltage pulses. To ensure the life of the vacuum switch, do not turn on the high voltage when the equipment is not being tested, especially do not continuously trigger the vacuum contactor under high pressure.

(6) With high voltage inside, please do not disassemble or open the shell to work at will.

(7) It contains high voltage, please do not disassemble or open the shell to work.
