*1 Regarding the output time limits:
Taking size, weight, and cost into consideration, the heat dissipation capability of the voltage generator that is used for withstanding voltage tests has been designed to be one half that of the rated output. Use the TOS5300 Series within the following limits. If you use the product in a manner that exceeds these limits, the output section may overheat, and the internal protection circuits may be activated. If this happens, stop testing, and wait until the TOS5300 Series returns to its normal temperature.
| Ambient temperature | Upper limit setting | Pause time | Output time | |
|---|---|---|---|---|
| t ≤ 40 °C | AC | 50 mA < i ≤ 110 mA | Greater than or equal to the output time | 30 min. max. |
| i ≤ 50 mA | Not necessary | Continuous output possible | ||
(Output time = voltage rise time + test time + voltage fall time)
*2: Regarding the test voltage waveform: Waveform distortions may occur if an DUT whose capacitance is dependent on voltage (for example, an DUT that consists of ceramic capacitors) is connected as the load. However, if the test voltage is 1.5 kV, the effect of a capacitance of 1000 pF or less can be ignored.Because the product’s high-voltage power supply uses the PWM switching method, if the test voltage is 500 V or less, the switching and spike noise proportions are large. The lower the test voltage, the greater the waveform is distorted. *3: For both True rms and Mean-value response, 50 ms or above response time is required to satisfy the measurement accuracy. *4: Regarding ammeter and judgment accuracy: During AC withstanding voltage tests, current also flows in the stray capacitance of items such as the measurement leads and jigs. This current that flows in the stray capacitances is added to the current that flows in the DUT, and the sum of these currents is measured.Especially if you want to perform judgments with high sensitivity and accuracy, it is necessary to consider methods to limit the current that flows in these stray capacitances, such as by adding upper and lower limits.
| Output voltage | 1 kV | 2 kV | 5 kV |
|---|---|---|---|
| When using 350 mm long test leads that are suspended in air (TYP) | 2 μA | 4 μA | 10 μA |
| When using the accessory, high test lead TL31-TOS (TYP) | 16 μA | 32 μA | 80 μA |
In case of 70 % humidity or higher, it is considerable to add 50 μA on the Limit value.
