TOS9300_Leakage Current Test-Other specifications

ItemTOS9303LC
Voltage conversionDisplays the estimated current converted with the preset supply voltage (Conv Voltage), based on the voltage supplied to the EUT and the measured current. (This is invalid in meter mode.)
Setting range80.0 V to 300.0 V, OFF
Resolution0.1 V
Power supply line polarity selectionSet the polarity of the power supply line to supply to the EUT to positive or negative.
Single fault mode (Condition) selectionSet the EUT single fault mode to normal, neutral line disconnection (Fault Neu), or protective ground wire disconnection (Fault PE).
Ground checkIn the touch current test between the enclosure and power supply line, if the EUT enclosure is grounded, Contact-FAIL occurs.
Measurement checkChecks the measurement function by shorting across the A and B terminals. If an error is found, the protection function is activated.
Supply voltage measurementAC LINE (EUT)Measurement range80.0 V to 250.0 V

Accuracy±(3 % of reading + 1 V)
Supply current measurementAC LINE (EUT)Measurement range0.1 A to 15.00 A
Resolution0.001 A
Accuracy±(5 % of reading + 30 mA)
Power measurement(active power)Measurement range10 W to 1500 W
Accuracy±(5 % of reading + 8 W) (with the supply voltage at 80 V or more, at a load power factor of 1)
Voltage measurement across the A and B terminalsMeasurement rangeDC10.00 V to 300.0 V
RMS10.00 V to 300.0 V
Peak15.00 V to 430.0 V
Input impedanceApprox. 40 MΩ
Accuracy *1±(3 % of reading + 2 V) (measurement range fixed to AUTO)
SELV detectionSet a voltage for detecting SELV. When the value is exceeded, the DANGER LED lights.
Setting range10.0 V to 99.9 V, OFF
Resolution0.1V
Measurement terminalRated voltageBetween the A and B terminals250 V
Between the terminals and chassis250 V
Rated current100 mA
Measurement categoryCAT-II
Valid terminal displayTerminals valid for measurement are indicated on the display.
110% terminalTerminal for supplying 110% voltage of the AC line.
Power supply for the EUTNominal voltage range100 V to 240 V, 50 Hz/60 Hz
Input voltage range (allowable voltage range)85 Vac to 250 Vac
Rated output capacity1500 VA
Maximum operating current15 A (Overcurrent protection is activated at approximately 15.7 A.)
Inrush current70 Apeak max. (within 20 ms)

*1 If voltage is measured with the A and B terminals open, measurements will be easily affected by induced voltage.
