It is a 2-in-1 designed device that allows the use of battery charger mode and power supply mode in a single unit.
Battery Charger "NPP Series" This product features two modes: battery charger mode and power supply mode. In battery charger mode, it performs excellently as a charger utilizing stage charging! However! In power supply mode, it is possible to charge the battery while also connecting a load to the unit, thereby providing a stable DC output! In the "3-stage charging" of the charger mode, it transitions from bulk charging to absorption charging and then to float charging. However, if a minimal load such as 5A is used, it may not transition to float charging and the charging will stop (it will not reach full charge). However, by using power supply mode, it allows for both full charging and stable supply to the load. Once the battery is fully charged, it will only supply the load stably. By disconnecting from the battery, it can also be used as an AC-DC power supply. For more details, please visit our website or view the catalog below.
