Distribució CC 500 (inclou 4 fusibles ANL + 1 fusible de 125 A)

The Mastervolt DC Distribution 500 is a compact DC power distribution unit. Its main function is to safely connect up to four different DC devices (such as battery chargers, inverters, alternators, or solar panels) to your battery bank. It also features intelligent fuse monitoring via the MasterBus network.

You can connect up to four different DC devices. This typically includes:

Battery chargersInvertersAlternatorsSolar panelsEach connection is protected by a fuse.

The DC Distribution 500 is designed to operate with battery banks rated at 12 V DC, 24 V DC, or 48 V DC.

The DC Distribution 500 can handle a continuous DC current of 300 A. It can also support a peak current of up to 500 A for a maximum duration of 5 minutes.

The DC Distribution 500 includes continuous monitoring of its fuse status. Thanks to its MasterBus connectivity, it provides precise information on the state of each fuse (OK or alarm) that can be accessed via a MasterBus display (such as a MasterView) or the MasterAdjust software. In case of a fault, a clear error notification is generated.

The DC Distribution 500 dimensions are 150 x 216 x 65 mm (Height x Width x Depth). Its weight is 1.2 kg.

The DC Distribution 500 features two green LED indicators that display the communication status and alarm conditions:

Simultaneous flashing at short, regular intervals: No MasterBus activity.Simultaneous flashing at irregular intervals: MasterBus activity.Alternating flashing at regular half-second intervals: Alarm condition.

Yes, the DC Distribution 500 has an IP21 protection rating. This means it is protected against solid objects larger than 12.5 mm (such as fingers) and against vertically falling water droplets. It is suitable for indoor installations where it is shielded from direct rain and significant water splashes.

The DC Distribution 500 is designed for easy installation. It features three mounting holes for secure attachment. The DC connections are protected by a robust housing that ensures optimal insulation.

The DC Distribution 500 comes with several items for installation and initial operation:

Four standard ANL fuses (two 80 A, one 125 A, one 160 A)One spare 125 A fuseA hex keyA MasterBus terminatorA plug-and-play MasterBus cableDC cable protection sleeves

Yes, several important precautions must be observed:

Installation must be performed by qualified, certified, and trained personnel in accordance with local regulations in force.Never work on the device or electrical installation while connected to a power source.Turn off all charging systems and battery connections before any intervention.Check the wiring at least once a year and immediately correct any faults.Never use the device in areas with a risk of gas or dust explosions.

Your components are connected to the main DC lines via the fuses. The DC Distribution 500 manages two groups (input and output). The sum of the fuse ratings for each group (input or output) must never exceed 500 A. For a charger/inverter combination, both groups must be considered.

Yes, the DC Distribution 500 is fully compatible with the MasterBus network. It comes with a plug & play cable for easy connection to the network, enabling remote monitoring and advanced configuration of the device.

To view the data and configure the DC Distribution 500 via MasterBus, you need a display device such as:

A MasterView series display (e.g., MasterView Classic or MasterView Easy) The MasterAdjust PC software (via a USB interface)

No, it is imperative to never connect a non-MasterBus device directly to the MasterBus network. This would void the warranty of all devices connected to the MasterBus. For communication with non-Mastervolt products, a Modbus interface is recommended, but not a direct connection.

The standard warranty period for the DC Distribution 500 is two years.

The warranty may be voided if the installation or any intervention on the device is not performed in accordance with the guidelines, instructions, and specifications contained in the user manual. Additionally, any modification of the device without prior written approval from Mastervolt, or the direct connection of a non-MasterBus device to the MasterBus network, may result in the warranty being voided.

The DC Distribution 500 comes as standard with four ANL-type fuses and one spare fuse:

Two 80 A fusesOne 125 A fuseOne 160 A fuseOne additional spare 125 A fuse

Yes, a MasterBus plug & play cable is included with the DC Distribution 500 delivery, enabling immediate connection to the MasterBus network.
