Mass 24/25-2 DNV - 24V | 25 A | 2 Outlet Battery Charger (DNV Approval)

Mass battery chargers are designed for the toughest conditions for professional, semi-professional and recreational purposes. Even under the most extreme conditions the products from the Mass series operate faultlessly, giving you round-the-clock output when necessary.

The sustainability and technologies that underpin the Mass concept have long been proven in practice. With an MTBF of 180,000 hours at full capacity and 24/7 use, the Mass products are ideal for the toughest tasks and any situation that requires a reliable power supply.

FEATURES

• Designed for the most difficult conditions.
• Lightweight, stainless steel, anodised aluminium casing.
• Coating of internal components prevents damage from damp or condensation to ensure a longer lifespan.
• Insensitive to electromagnetic effects from other devices.
• Suitable for every type of battery, also charges entirely empty batteries.
• Delivered as standard with temperature sensor.
• Full power at temperatures of up to 45˚C.
• Load capacities from 80 to 1000 Ah or more.
• Stable power supply of 24 and 48 V, even without batteries.
• The Current Control function allows you to reduce the battery charger power to prevent blowing the fuse, even when the voltage drops.
• Parallel switching possible using multiple battery chargers.
• Connections in accordance with CE, ABYC A-31 and IEC60945.
• Certified by RRR, RS, DNV (24/25, 24/50, 24/75, 24/100 models) and Germanisch Lloyd, Lloyd (24/75, 24/100 models).
• Type approval for application in safety zones A, B and C.

FOR PROFESSIONAL USE: GMDSS

Professional users will benefit from a front display with GMDSS alarm functions GMDSS stands for Global Maritime Distress and Safety System, an internationally agreed-upon set of safety procedures, types of equipment, and communication protocols that is a requirement for the SOLAS (Safety Of Life At Sea) convention and uses DSC and satellite communication.

MASTERBUS COMPATIBLE

Mass battery chargers can be easily connected to a MasterBus network with only one cable and one connection. You can also choose central, local or remote monitoring, configuration and control of your system.
