During normal operation, the LED is lit steadily without flashing. If the overcurrent protection function operates intermittently, the LED may flash due to the following causes. Please check for the existence of these causes.
The overcurrent protection function is operating
When the overcurrent protection function operates, the output voltage will be intermittent and the output LED will flash.
The capacity of the external capacitor is too large
If you connect an external capacitor that exceeds the capacity listed in the instruction manual, overcurrent protection will be activated at startup and the output LED will flash.
When the overcurrent condition is cleared, the output voltage returns to normal and the LED is lit steadily.
