Description

The Mastervolt Mass 24/25-2 DNV is the DNV type-approved version of the Mass 24/25, a 24V/25A battery charger built for the toughest professional, semi-professional and recreational conditions. Running from a single-phase 230V AC supply (180 to 265V, 50/60 Hz), it delivers reliable round-the-clock output even in extreme environments. DNV type approval makes it the right choice for commercial and classed vessels where independently certified equipment is required.

This model has two battery outlets, charging a main bank of 50 to 250 Ah at up to 25A plus a second output at 3A to keep a starter or auxiliary battery topped up. A lightweight, anodised aluminium casing with coated internals resists damp and condensation, and the automatic IUoUo three-step+ characteristic charges Gel, AGM, wet and Lithium Ion batteries. Integrated MasterBus connectivity allows central, local or remote monitoring, while the Current Control function protects fuses during voltage dips.

What makes this the DNV version of the Mass 24/25?
It is the DNV type-approved variant, carrying DNV GL approval (and a DNV-GL type approval certificate), so it can be specified on commercial and classed vessels that require independently certified charging equipment.
How many battery outputs does it have?
It has two outputs: the main output charges a bank of 50 to 250 Ah at up to 25A, and a second 3A output keeps a starter or auxiliary battery topped up.
What input supply does it need?
It runs from a single-phase 230V AC supply, with a working range of 180 to 265V at 50/60 Hz.
Can it charge Lithium Ion batteries?
Yes. It uses an automatic IUoUo three-step+ characteristic for Gel, AGM, wet and Lithium Ion batteries and communicates directly with Lithium Ion batteries over MasterBus.
Which approvals does it hold?
It complies with CE, ABYC A-31, DNV GL, RRR and RMRS, and is GMDSS compatible to help meet SOLAS regulations.
