Charge Status Indicator of The UL Class 2 Power Supply 25.2V 3A

Red

● Charging or disconnect form the batteries

Green

● Batteries fully charged

Red flash

● Reverse connection with the battery

● Faulty battery

● Short circuit

When charger is disconnected from the mains, or battery is fully charged, a relay is used to automatically disconnect the charger from the batteries, to prevent the battery from flowing back (Backfeed).
