Inverter AC Master 12/1000 – 230 V 50 Hz – code: 02-80-11000 – Mastervolt

AC Master 12/1000 Mastervolt Inverter – onboard AC power supply

The’AC Master 12/1000 by Mastervolt is designed to convert the energy available from a battery to 12 V into power supply AC 230 V per l’utilizzo di utenze in corrente alternata. È una soluzione indicata per applicazioni in ambito nautico e impiantistico dove serve disporre di una presa AC a bordo, con una gestione chiara dello stato di funzionamento tramite indicatori LED.

This version is identified by the code 02-80-11000 and belongs to the AC Master family, designed for neat installations and practical use in maintenance and operation. pure sine wave allows the power supply of devices that require a stable and “clean” voltage quality, in line with the manufacturer's specifications.

Features and technical details

AC output and waveform quality

The inverter provides an alternating current output with selectable voltage between 200/220/230/240 V and frequency 50/60 Hz (adjustable). The output waveform is declared pure sine wave, a useful feature when an AC power supply compliant with the requirements of many devices is desired.

Battery side power supply

The nominal battery voltage is 12 V. The manufacturer indicates a recommended battery capacity equal to 130 Ah. When designing the system, it is advisable to also consider the type of loads, usage times, and the adequacy of wiring and protections, according to good installation practices.

Available power

Regarding power, the following values are reported (cos phi 1):

• Continuous power at 25 °C / 77 °F: 1000 W
• Continuous power at 40 °C / 104 °F: 1000 W
• Peak power (1 min.): < 1150 W
• Peak power (1 s): < 1750 W

These data help to properly size the inverter according to the expected loads, distinguishing between continuous use and short-term surge demands.

Connections and AC socket

The AC connection is via EU type socket (Schuko). The manufacturer also indicates items with alternative plugs:

• UK plug (item no. 28211000)
• NZ/AU plug (item no. 28411000)

Insulation, efficiency and signals

• Galvanic isolation: yes
• Efficiency: 92 %
• Display/readings: LED indicators for battery voltage, AC load level and status
• Alarms: clean alarm contact

The LED signals allow immediate monitoring of the main parameters, while the clean alarm contact can be useful for integration with monitoring or signaling systems on board (depending on system configuration).

Dimensions, weight and certifications

• Dimensions: 200 x 372 x 83 mm (7.9 x 14.6 x 3.3 inches)
• Weight: 3.3 kg (7.3 pounds)
• Certifications: CE, E-mark, RCM

Typical applications (nautical and onboard plant engineering)

L’AC Master 12/1000 è indicato per contesti in cui si desidera disporre di alimentazione AC partendo da una batteria a 12 V, ad esempio su imbarcazioni, veicoli o installazioni tecniche dove l’energia è accumulata in DC e serve una conversione in AC per utenze a 230 V.

In ambito nautico può essere considerato per:

• Powering AC loads when shore power or a generator is not available.
• Support for instrumentation and small onboard services requiring alternating voltage.
• Systems where an integrated Schuko socket is useful for quick connections.

The ability to set output voltage and frequency (within the indicated values) allows adapting the output to the system's needs, respecting the manufacturer's specifications.

Operational advantages

Pure sine wave for quality AC supply

The pure sine wave is a distinctive feature for those who want an AC output with a waveform suitable for many devices, reducing the risk of incompatibilities typical of non-sinusoidal waveforms (depending on load characteristics).

Immediate control via LED

The LED indicators dedicated to battery voltage, AC load level and status make it easier to check operation during daily use and system monitoring activities.

Integration with external signals

The presence of a clean alarm contact provides a basis for bringing alarm information to remote panels or supervision systems, when provided for in the installation.

Galvanic isolation

The’galvanic isolation declared by the manufacturer is a relevant aspect in many installations, especially where attention is paid to electrical separation between sections of the system.

Usage and installation notes

To achieve correct inverter operation and orderly onboard integration, it is advisable to:

• Verify that the 12 V battery and its capacity are adequate for the intended use (the manufacturer recommends 130 Ah).
• Properly size wiring and protections according to the system and applicable regulations, especially on the DC side.
• Consider the continuous power and the load peaks (surges) of the loads, referring to the declared values.
• Set output voltage and frequency according to needs (within the indicated ranges) and consistent with connected devices.
• Use the Schuko socket and any plug accessories (UK or NZ/AU) only if relevant to the required configuration.

For commissioning and any integration with alarm or monitoring systems, follow Mastervolt instructions and good installation practices in the nautical field.
