AC Hipot Testing with Stable Output (Input Voltage Variation: ±0.3%)

Conventional hipot testers utilize a slide transformer to output AC line voltage. This design is susceptible to input voltage fluctuation, with outside electrical influence affecting the test results. This can result in distorted voltage being applied to the EUT which can cause product malfunctions down the line due to component malfunction. The TOS9300 series utilizes a highly efficient PWM amplifier capable of stable high-voltage output that is unaffected by changes in the AC power line. The TOS9300 series allows for safe, stable, and highly reliable tests regardless of AC power line instability.

Automatic Testing Feature

Tests can be combined and configured to execute automatically over long periods of time. Automatic tests are composed of programs and steps, which can be configured to initiate one after another.

Contact/Protective Conductor/ Patient Leakage Current Test

The TOS9303LC can conduct leakage current (patient current) tests for highly sensitive medical devices. Measurement networks can be easily configured via the front panel.

Electrical safety standard testing for automotive components

Compatible with both AC and DC, the TOS9303LC complies with a wide variety of safety tests for EV batteries, automotive charging devices and charging connectors. This "all-in-one" safety analyzer can meet the needs of nearly all automotive electrical safety standards.
