Vahelduvvoolu võimsuse analüsaator

The AC power analyzer is a multifunction measurement device designed to monitor your electrical installation. It allows real-time visualization of voltage, current, frequency, power factor (Cos Phi), and apparent power from 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.

When configured on the MasterBus network, you can choose between three operating modes: shore power (Shore), generator power (Generator), or inverter power (Inverter).

Current is measured indirectly using a current transformer (current coil) 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 harsh marine environments. It has an IP65 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 tight spaces.

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

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

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

Analyzer control and configuration are fully based on the MasterBus network. You will need a compatible display, such as the MasterView Easy panel or MasterView System software, to view measurements and set up 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 features several indicators:

Yellow LED (Mode): indicates the relay status.

Green LED (AC ok): signals the presence of AC power without errors.

Red LED (AC fail): alerts to out-of-range voltage or frequency.

Green LED (MasterBus): indicates network communication status.

Never connect a non-MasterBus device directly to the MasterBus network. To enable communication between third-party equipment and 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. Ring networks (loops) or T-connections are strictly discouraged as they 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 perform 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, via the MasterBus network event system, you can configure the analyzer to initiate an action on another connected device. For example, it can command a generator to start if shore power becomes insufficient.

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