The TOS9300 series is a high performance electrical safety analyzer that complies to a wide range of universal standards. Hipot, Insulation Resistance, Ground Bond, Leakage Current (touch current and protective conductor current) and partial discharge can all be tested. A total of 6 models are available for standard compliance tests in a wide variety of applications including R&D, quality assurance manufacturing lines and laboratory tests. Features A brand-new 7-inch LCD display allows for easy access to your custom settings, standard outlines and blueprints for easy operation. 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 Automatic Testing Feature Tests can be combined and configured to execute automatically over long periods of time. Automotic tests are composed of programs and steps, which can be configured to initiate one after another.
