AC Master 12/2500 (230V)

Safe AC power for recreational and semi-professional use

These affordable pure sine wave inverters convert 12V or 24V battery power into stable 230V 50/60Hz or 120V 50/60Hz grid power, making them ideal for recreational and semi-professional applications. The AC Master series inverters are easy to install and provide maximum power even in difficult conditions. The pure sine waveform ensures the highest quality power, essential for the operation of sensitive equipment. The use of high-frequency switching technology eliminates any noise due to vibrations and hums.

These solid inverters provide the comforts of home when you are away from the grid, with an excellent quality/price ratio.

Characteristics

• Pure sine wave protects sensitive equipment.
• They deliver full power and high peaks even in difficult conditions.
• Automatic energy saving system for long-term use.
• Compact and lightweight design, saving installation time.
• Reliable and safe: protected against overtemperature, overload, short circuit, high and low battery voltage.
• Variable speed fan reduces noise at low power.
• Optional remote control for switching off the inverter and connected equipment (not available for 300 and 500 W models).
• Convenient sockets for all models. Models 2500/3500 also equipped with clamps.

In addition, the 2500/3500 Watt models offer:

• Possible parallel connection from 2 to 15 units for high power or three-phase systems.
• Automatic transfer system between AC sources.

• Applications

  Both recreational and semi-professional use, where there is a shortage or absence of the electrical network. Applications include: lighting, household appliances, electric kitchens and tools. For (mobile) applications at home, in the office, in service vehicles, or during vacations.
