Features Color LCD Screen for Improved Visibility! A brand-new 7-inch LCD display allows for easy access to your custom settings, standard outlines and blueprints for easy operation. (See Exterior Design P10/Display P11) I/V Monitor Terminal (Analog Monitor) Signal outputs on the rear panel I/V terminal allow the user to monitor current/voltage waveforms during hipot tests with only an oscilloscope. Current sensors and high voltage probes not required. Oscilloscope TOS9300 Series Rear panel Can connect with an oscilloscope using a BNC cable. *There is no BNC cable option available. Users...

Universal Input Support ● Global Support Automatic Testing Feature TOS9300 Series supports universal input for varying input voltages around the world. 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. ● Programmable Output Frequency Stable output frequency not dependent on input power source. Testing voltage is supplied at a stable 50/60Hz frequency. GProgram schematic Step 1 AC Hipot Testing with Stable Output [Input Voltage Variation: ±0.3%]...

Features Programmable Detection Response Speed Conventional withstanding voltage testers are generally used to only detect insulation breakdown, and cannot make judgements on instantaneous discharge currents like partial discharge. However, the TOS9300 series is equipped with 5 levels of response speed settings to accurately detect low levels of insulation breakdown. Small discharges not visible to conventional withstanding voltage testers are easily detected with the TOS9300 series. Value Mean-value response type current detector. This is similar to the current detection response of...

Rise Time/Fall Time Control Function The rise time control function prevents unnecessary stress from being applied to the EUT. Multi-Channel Testing System (Option) ● Rise Time control function The rise time control feature allows you to gradually increase voltage to a set value while AC/ DC hipot tests are conducted. Vo l t a g e r i s e t i m e s c a n b e set from 0.1s to 20 0.0s at a resolution of 0.1s. The TOS9320 high voltage scanner allows for rapid distribution of testing voltage from the main unit to multiple testing points for withstanding voltange and insulation resistance...

Application Leakage Current Test Compatible with medical device leakage current testing (patient current)! (TOS9303LC only) ●Test Example Insulation transformer What is patient leakage current testing? Medical device This test measures current flowing from the point of contact between a medical instrument and a simulated human body network to the ground. If the measurement does not exceed a value deemed harmful to a human being as defined in international safety standards, the product is considered safe and compliant to electric shock prevention requirements. Patient fitting site Primary...

PV (solar battery) module withstanding voltage/insulation resistance testing Withstanding voltage tests such as IEC61730-2 and JIS C 8992-2 require testing voltage to be drastically increased (4 times the maximum system voltage + 2000 V) and maintained for 1 minute. [Voltage 1000 V adaptation grade A example] 1000 V × 4-fold + 2000 V = Test voltage : DCW Easily compatible with 1000 V PV modules as well! Also fitted with a highly accurate ammeter GMeasurement accuracy: ±(1% of reading + 2 μA) frame LOW terminal connected to frame Electrode HIGH terminal connected to short circuit output...

Exterior Design Front panel ●TOS9303LC DANGER LED Lights red when the power is turned on, when a test is in progress, when a high voltage is being output, or when there is residual voltage at the output terminals. On the TOS9303LC, the LED also lights red when supply voltage is being supplied to the EUT. Menu keys Switch display. Used for external keyboard as well as memory for settings and test results. Also used for import/ export of programs and firmware updates. Withstanding voltage, insulation resistance Common for all models. START switch Start test. Numeric keypad For value input....
