Detailed description

The Mastervolt Mac Plus 48/24-30 IP23 CZone is a bidirectional DC-DC converter-charger designed for 48V/24V electrical systems with a common negative ground. With a 30A output current on the low-voltage side (24V) and a power output of 720W, it stabilizes power supply for your 24V equipment from a 48V battery bank, or vice versa.

Bidirectional operation and versatility

Unlike a unidirectional DC-DC converter, the Mac Plus can reverse the current flow direction. This allows, for example, charging a 48V service battery via a 24V alternator, or boosting a 24V starter battery from the 48V bank. This function can be controlled via a remote contact, a MasterBus event, or a CZone circuit. The Mac Plus 48/24-30 differs from the 48/12-50 model in its output voltage (24V instead of 12V), and is intended for boats with a 24V network for high-power equipment (motors, thrusters, etc.).

CZone and MasterBus integration

This model is CZone-certified and MasterBus-compatible, enabling deep integration with Mastervolt energy management systems. Via the CZone network, you can configure charge profiles, set alarms, and create automation rules (e.g., load shedding in case of low battery voltage). The Mac Plus comes with a 1-meter Mastervolt-CZone connection cable and a MasterBus terminator.

Installation and protection

With an IP23 protection rating, it resists water spray and dust, making it suitable for installation in a ventilated technical compartment, away from direct spray. The package includes a battery temperature sensor to optimize charging based on temperature. Connections are made via screw terminals for cables up to 10 mm² (low side) and 6 mm² (high side).

Expert opinion

Pol CONIN

Digital Manager

« A reliable bidirectional DC-DC converter for 48V/24V systems »

The Mac Plus 48/24-30 is a bidirectional DC-DC converter specifically designed for 48V systems on boats that need to power 24V equipment (thrusters, windlasses, etc.). Its ability to reverse the charge direction is a major advantage for redundancy: in case of a 48V battery bank failure, it can keep the 24V battery operational. CZone integration allows precise energy priority management but requires configuration via the CZone software. The IP23 enclosure is well-ventilated, but avoid installing it in an environment where moisture could accumulate. For maximum reliability, I recommend using external fuses on each branch.

Frequently Asked Questions

Need help? Contact us

Can the Mac Plus 48/24-30 operate with both voltage polarities?

Yes, the Mac Plus 48/24-30 is a bidirectional converter-charger. It can convert 48V to 24V, or reverse the current flow to convert from 24V to 48V. This function is controllable via a remote contact, a MasterBus event, or a CZone circuit.

What is the difference between the Mac Plus 48/24-30 and the other models in the Mac Plus range?

The 48/24-30 model is distinguished by its operating voltages: it accepts a 48V input and provides a 24V output (or vice versa in bidirectional mode). Other models in the Mac Plus range may have different input/output voltages, such as 48/12V or 12/48V.

What are the main applications of the Mac Plus 48/24-30?

The Mac Plus 48/24-30 is suitable for several applications, including:

- Stabilizing the power supply for 24V equipment from a 48V battery bank.

- Charging a 48V service battery via a 24V alternator.

- Boosting a 24V starter battery from a 48V bank.

- Use as a three-stage battery charger or as a stabilized DC power supply.

Is the Mac Plus 48/24-30 suitable for marine environments?

Yes, with an IP23 protection rating, the Mac Plus 48/24-30 resists water spray and dust. It is designed to be installed in a ventilated technical compartment, protected from direct spray. It is also compatible with common-negative installations, typical in marine applications.

Where should I mount the Mac Plus 48/24-30 converter?

The Mac Plus 48/24-30 must be mounted on a flat and solid surface using four M5 screws. It requires a minimum clearance of 10 cm (4 inches) on all sides to ensure adequate ventilation. Avoid mounting it directly above batteries that may emit corrosive fumes.

Can I use the Mac Plus 48/24-30 to charge lithium batteries?
