410. Withstand Voltage
This series is designed to withstand 3.0kVAC between input and output, 2.0kVAC between input and
terminal
and
500VAC between output and
terminal each for 1 minute. When testing withstand voltage, set current
limit of withstand voltage test equipment at 20mA (Output
terminal : 50mA). The applied voltage must be
gradually increased from zero to testing value and then gradually decreased for shut down. When timer is used,
the power supply may be damaged by high impulse voltage at timer switch on and off timing. Connect input and
output as follows.
■ Input Output (dotted line)
: 3.0kVAC, 1min (20mA)
Input
terminal (solid line) : 2.0kVAC, 1min (20mA)
■ Output
terminal : 500VAC, 1min (50mA)
Note 1 : DRJ15, DRJ30 have monolithic ceramic capacitor in secondary circuit to
.
Some of the withstand voltage tester may generate high voltage at the matching with monolithic
ceramic capacitor and may cause the unit damage.
So, please check the waveform of applied voltage.
Note 2 : In case of using external noise filter, capacitance between "Input and
" might be increased.
When testing withstand voltage between "Input and Output", there is a possibility exceeding withstand
voltage between "Output and
" (500VAC). Please check the voltage between "Output and
".
If the voltage exceeding withstand voltage, please add external capacitor to
"Output and ". It can decrease the voltage.
On the other hand, no need to check the voltage in case of "Output and " is shorted.
