Mastervolt Mass Battery Charger with 3 x 400V Inputs (24V / 100A)
Pickup available at Mercury Yacht Harbour
Usually ready in 2-4 days
Description
The Mastervolt Mass 24/100-3ph is a 24V/100A battery charger built for the toughest professional, semi-professional and recreational conditions. It runs from a three-phase 400V AC supply (365 to 550V, 50/60 Hz), making it ideal for larger vessels and industrial installations where a balanced three-phase feed is available. Even under extreme conditions the Mass series operates faultlessly, delivering round-the-clock output when it is needed.
Housed in a lightweight, anodised aluminium casing, the charger has internal components coated to prevent damage from damp or condensation for a longer lifespan. It charges every battery type, including Lithium Ion, using an automatic three-step+ characteristic and communicates directly with the battery over the integrated MasterBus network. The Current Control function prevents fuses from blowing when the input voltage drops, and parallel switching allows multiple chargers to work together.
