INSTRUCTION MANUAL
3-13. Withstand Voltage
This series is designed to withstand 3.0kVAC between input
and output, 2.0kVAC between input and PE (Chassis) and
500VAC between output and the PE (Chassis) each for 1 mi-
nute. When performing this test, set current limit of the with-
stand voltage test equipment to 20mA ( Output - PE (Chassis) :
100mA ). The applied voltage must be gradually increased
from zero to the test value and then gradually decreased for
shut down. When timer is used, the power supply may be
damaged by high impulse voltage during timer switch on and
off. Connect input and output as follows.
Input ~ Output (dotted line )
3kVAC 1min. ( 20mA )
Input ~ PE (Chassis) (solid line )
2kVAC 1min. ( 20mA )
