Mastervolt Chargemaster 24/30-3

ChargeMaster 24/30-3

Make the most of your batteries with the ChargeMaster series,
plugging in and charging anywhere in the world. Mastervolt’s
ChargeMaster guarantees fast and complete charging of your
batteries no matter where you are. Thanks to Mastervolt’s
innovative 3-step+ charging process, batteries also perform better
and last longer.

All ChargeMasters can be easily connected to a MasterBus network
with only one cable and one connection (with the exception of the
ChargeMaster 12/10, ChargeMaster 12/15-2 and ChargeMaster 24/6).
What’s more, you have the option for central, local or remote
monitoring, configuration and control of your system.

Clear Display

A clearly lit display on the ChargeMaster provides all essential
information: charge current, charge voltage, charge phase and
battery content measurement and/or battery condition measurement as
a percentage of available Ah capacity. The display also provides an
indication of MasterBus communication. Three buttons adjacent to
the read-out panel allow for easy operating of the entire
system. 

The ChargeMaster is available in various models to guarantee you
the ideal battery charger for any situation and demand.

  features.
• Charging capacity up to 1000 Ah.
• Easy to connect and quick to install.
• Can charge multiple battery banks simultaneously.
• Built-in system functionality (MasterBus) in combination with
  other Mastervolt products.

• Supplies your system without battery.

Charging your batteries with every voltage

The Mastervolt ChargeMaster supplies a maximum capacity wherever
you are via auto-ranging. Auto-ranging ensures perfect fully
automatic operation anywhere in the world, regardless of the
available mains voltage (90-265 V AC, 50 or 60 Hz). The 3-step+
charging technology guarantees fast and complete charging, while
the cos phi 1-regulation gets the most out of limited generator
capacity.

Robust Connections 

Solid metal-to-metal connectors equipped with strain relief
prevent corrosion and overheating.

Charging multiple battery banks

The ChargeMaster series has three equal charge outputs. Those of
the smaller ChargeMaster models are pre-installed with two metres
of cable for a plug and play solution, while the heavier models
have one full output (for example for your service battery) and two
outputs of 10 A, ideal for your starter batteries.

DC Power Supply

Even if the batteries are not connected, Mastervolt ChargeMaster
battery chargers can provide a constant DC output allowing you to
turn on lights or keep the fridge cold.
