PROTECTIONS
| PROTECTION | DESCRIPTION |
|---|---|
| Input under/over-voltage | When the AC input voltage is lower than 150Vac, the charger stops working and an under-voltage alarm occurs; when the AC input voltage is higher than 280Vac, the charger stops working and an over-voltage alarm occurs; |
| Input overcurrent | The charger reduces the output power to ensure that the input over current (active monitoring) thresholds are not breached. |
| Output over-voltage | If output voltage exceeds the internal OV threshold, the charger immediately cuts the output relay and gives an alarm. |
| Output overcurrent | If load current exceeds the internal OC limit, the charger immediately cuts the output relay and gives an alarm. |
| Output short circuit | If the output is short-circuited, the charger shuts down output with current limit and an alarm is issued. |
| Reverse polarity & no-load | If the battery is connected in reverse, the charger shuts down output and alarms (reverse polarity protection not active during Activation mode). If battery voltage is missing or <⅓ of rated pack voltage, the charger alarms and gives no output. |
| Automatic shutdown | If charging time or charging end voltage exceeds the internal maximum limit, it stops charging and alarms. |
| Over-temperature | If internal or ambient temperature goes above the set value, it first reduces current (derating), then stops and alarms; charging resumes automatically when temperature falls to the recovery point. With an external probe, it can also monitor battery/ambient temperature. |
