NLDC-25 Dual Battery Isolator and Charger

The NLDC-25 from National Luna is a DC to DC battery charger and isolator for a dual-battery system.

It will charge an auxiliary or service battery from a vehicle alternator or Solar panel up to 25A output current.

Traditional 12V and 24V vehicle alternators as well as variable voltage alternators are supported.

The integrated MPPT solar regulator provides a maximum output power of 375W but can support solar panels higher than this.

Solar panel voltages up to 42V can be connected.

The NLDC-25 features a 6-stage charge algorithm that is suitable for any Lead-Acid battery type as well as automotive Lithium-Ion batteries.

3 safety stages analyse the battery and can detect batteries that are damaged and unable to accept charge.

Temperature compensation is used to optimise the output voltage, ensuring safe and full battery charging under various conditions.

The NLDC-25 supports the connection of a remote monitor that displays information about the system and battery levels to the user on a high-contrast LCD screen.

The NLDC-25 has a IP67 rating for harsh environments and is protected against reverse-polarity, over-voltage, over-temperature and over-current conditions.
