Equipments Overview

This tester is specially designed to evaluate transient overvoltage resistance, as well as to verify electrical clearance and creepage distance between components.
Suitable Test Samples
Ideal for testing a wide range of electronic devices, including:
• Household Appliances
• Audio/Video Equipment
• Consumer Electronics
• Similar Low-Voltage Electronic Products
Key Feature
During a breakdown test, the unit simulates real-world failure conditions:
Visible spark and audible noise when breakdown occurs
Peak voltage drops sharply (nearly to zero) upon discharge
Repeatable behavior during subsequent tests at same voltage, indicating reliable fault detection
