3-10. Withstand Voltage
This series is designed to withstand 3.0kVAC between input
and output, 2.0kVAC between input and FG (Chassis) and
500VAC between output and the FG (Chassis) each for 1
minute. When testing withstand voltage, set current limit of
the withstand voltage test equipment to 20mA ( Output - FG
(Chassis) : 100mA ). The applied voltage must be gradually
increased from zero to the 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. Connect input and output as follows.
Input ~ Output (dotted line )
3kVAC 1min. ( 20mA )
Input ~ FG (Chassis) (solid line )
2kVAC 1min. ( 20mA )

3-11. Alarm Indication

LED on the panel indicate whether the power supply unit
is working properly.
• The green LED is on and red LED is off in normal
operation.
• The red LED turns on when O/P voltage drops below
approximatly 20V (ex: over current protection output
voltage unregulated, output shorted conditions).
• The green LED goes out when output shorted (output
voltage below 2V).
Both LEDs turn off on the condition of input power
•
source failure or power supply damaged.
