Krmilnik baterije MasterShunt 500 CZone

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

The MasterShunt 500 is highly versatile. It is compatible with Gel, AGM, flooded (wet) lead-acid, and Lithium-Ion battery 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 on 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 enclosure has IP21 ingress protection. This means it is protected against condensation and vertically falling water droplets. It must be installed in a dry, enclosed, and well-ventilated space.

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

Yes, this is one of its major advantages. It comes with an internal busbar that can be easily replaced with 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 on MasterBus, CZone, and NMEA 2000 protocols.

The state of charge (SOC) is dynamically calculated by an advanced algorithm that integrates 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 autonomously starting a generator when the battery charge state reaches a predefined critical threshold.

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

The two LED indicators show the device status:

Slow simultaneous flashing: No network activity.Irregular simultaneous flashing: Network activity in progress.Alternating fast 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 uses about 23 mA in normal operation and less than 1 mA in standby mode (when the MasterBus network is disabled).

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

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

The battery charger, like all your electrical consumers, must be connected to 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 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 charge profile).
