AC Master 12/2500 (230 V)

Reliable AC power for recreational and semi-professional use

These affordable sine wave inverters convert 12 or 24 V battery voltage into reliable 230 V 50/60 Hz or 120 V 50/60 Hz grid power, making them ideal for recreational and semi-professional applications. The AC Master series is easy to install and delivers full output, even under the most demanding conditions. The pure sine wave technology provides an outstanding power quality, ensuring the correct functioning of sensitive equipment. The usage of high frequency switching technology eliminates any annoying humming and buzzing sounds.

Representing complete value for money, these ruggedly built inverters provide essential home comforts when you’re far from the nearest grid connection.

Features

Pure sine wave technology protects sensitive equipment.
Delivers full output at high peak power under the most demanding conditions.
Automatic power saving system for extended runtime.
Compact and lightweight design, saving valuable installation time.
Reliable and safe operation; protected against over-temperature, overload, short circuit, high or low battery voltage.
Variable speed fan for quiet operation at low power.
Optional remote control for instant switch off of the inverter and all connected equipment (not available for the 300 and 500 W models).
Convenient plug connection for all models, 2500/3500 Watt models also hard wired.

In addition, the 2500/3500 Watt models offer:

Combine 2 up to 15 units to obtain high power or 3-phase systems.
Integrated transfer system, switches automatically between AC power sources.

Applications

Both recreational and semi-professional use, where grid power varies or is unavailable. Applications include lighting, appliances, electric cooking and power tools. For (mobile) applications in your home, office or service vehicle, or during your holidays.
