AC teljesítményanalizátor

The AC power analyzer is a multifunction measuring device designed to monitor your electrical installation. It allows you to view in real time the voltage, current, frequency, power factor (Cos Phi), and apparent power of your AC sources (shore power, generator, or inverter).

Depending on the selected mode, the device measures and displays AC voltage, AC current, frequency, apparent power (VA), power factor (Cos Phi), MasterBus network voltage, as well as the device's temperature.

During configuration on the MasterBus network, you can select from three operating modes: shore power (Shore), generator power (Generator), or inverter power (Inverter).

Current is measured indirectly using a current transformer (CT) with a 100:5 ratio. This component is supplied with the analyzer and ensures optimal isolation and accuracy.

Yes, this module is designed to withstand demanding marine environments. It has an IP65 protection rating, making it fully protected against dust and water jets.

The analyzer is a very compact module. It measures 80 x 181 x 28 mm (height x width x depth) and weighs only 0.53 kg, making it easy to integrate into confined spaces.

The device is supplied complete for standard installation. The box contains:

This analyzer stands out for its ability to serve as a specific MasterBus interface for Mass Sine range converters from Mastervolt, thanks to its dedicated RJ12 port.

The device integrates a programmable dry contact (potential-free) capable of switching a relay with a maximum capacity of 5A at 250V. This allows automating certain functions of your electrical system, such as the automatic start of a generator set.

Control and configuration of the analyzer are entirely based on the MasterBus network. You will need a compatible display, such as the MasterView Easy panel or the MasterView System software, to view measurements and configure the device.

The AC power analyzer is compatible with standard electrical grids. During initial setup, you can select a nominal voltage of 120V AC or 230V AC.

The device has several indicators:

Yellow LED (Mode): indicates the relay state. Green LED (AC ok): signals the presence of AC power without error. Red LED (AC fail): alerts to voltage or frequency out of limits. Green LED (MasterBus): indicates network communication status.

Never connect a non-MasterBus device directly to the MasterBus network. To interface third-party equipment with the Mastervolt network, use a dedicated interface such as the Modbus interface.

Connection is made very simply using standard UTP patch cables. The analyzer has two MasterBus ports to be daisy-chained with other network devices. Do not forget to install a terminator at both ends of the network.

No, the MasterBus network must be installed in a linear daisy chain. Creating ring networks (loops) or T-connections is strictly discouraged as it may disrupt data communication.

No, the current transformer with a 100:5 ratio is included with the AC power analyzer. You do not need to purchase it separately to take current measurements.

If voltage, current or frequency values exceed the configured limits, the red "AC fail" LED lights up continuously and an alarm can be triggered on your MasterBus display to alert you to the issue.

Yes, thanks to the MasterBus network's event system, you can configure the analyzer to initiate an action on another connected device. For example, it can command the start of a generator if the shore power becomes insufficient.

To connect the AC power analyzer to a Mass Sine inverter, you must use the dedicated communication port on the analyzer and connect it with a cable equipped with an RJ12 connector.
