Regulator MasterShunt 500 CZone do akumulatorów

This is an advanced digital battery monitor designed to monitor your battery bank. It measures with high precision the voltage, charge and discharge current, state of charge (SOC) and remaining runtime in real time.

The MasterShunt 500 is highly versatile. It is compatible with batteries of Gel, AGM, flooded lead-acid, and Lithium-Ion technologies.

This model supports a wide range of electrical systems. It is compatible with 12 V, 24 V, 36 V, and 48 V battery banks.

Unlike the standard model, which is limited to the MasterBus environment, the CZone version (77020115) features native communication with CZone and NMEA 2000 networks, enabling full automation and direct integration into these networks.

To ensure accurate measurements and reduce voltage drops, the controller must be installed as close as possible to your batteries, between the battery bank and your loads or chargers.

The housing has IP21 protection. This means it is protected against condensation and vertical drops of water. It must be installed in a closed, dry and well-ventilated space.

It supports a continuous current of 300 A. It can also handle significant load spikes: 400 A for 10 minutes, 500 A for 5 minutes, and up to 600 A for 2 minutes.

Yes, that is one of its major advantages. It comes with an internal bus bar that can be easily replaced by a main fuse of ANL or Class T type, allowing for space savings and a more secure installation.

This controller is designed to communicate seamlessly over MasterBus, CZone, and NMEA 2000 protocols.

The state of charge (SOC) is dynamically calculated by an advanced algorithm that incorporates the charge efficiency factor (C.E.F.) and Peukert's exponent, ensuring an extremely realistic and reliable estimation.

Yes, the MasterShunt has advanced programming functions. It can trigger automated events on the network, such as the autonomous startup of a generator when the battery charge state reaches a predefined critical threshold.

The 77020115 model comes with a 1-meter RJ45-M12 CZone/MasterBus connection cable, a temperature sensor, and the necessary mounting accessories (end caps, CC cones, bolts).

The two LEDs indicate the device status:

Slow simultaneous flashing: No network activity.
Irregular simultaneous flashing: Network activity in progress.
Fast alternating flashing: Alarm condition.

Yes, it is entirely possible to install multiple MasterShunts in parallel if your electrical installation requires handling currents exceeding the capacity of a single unit.

No, its power consumption is very low. It consumes about 23 mA in normal operation and less than 1 mA in sleep mode (when the MasterBus network is disabled).

The MasterShunt integrates the MasterConnect system. With the supplied transparent middle piece, it can be physically and directly coupled to a 500 DC Distribution module, greatly simplifying wiring.

You can configure multiple custom alarms, including a low voltage warning, a low state of charge, or an abnormally high voltage.

The battery charger, like all your electrical consumers, must absolutely be connected on the load side of the MasterShunt, not directly to the battery terminals, so that the current is measured correctly.

The system automatically resets to 100% when it detects that the battery is fully charged. This occurs when the battery voltage and charging current reach specific values (configurable) for a defined duration (e.g., 30 seconds or several hours depending on the charging profile).
