Detailed description
Detailed description
The Mastervolt AC Master 12/3500 inverter converts 12 V battery voltage into reliable 230 V AC at 50/60 Hz with a pure sine wave output. This power conversion solution is suitable for recreational and semi-professional applications, ensuring safe operation of sensitive electronic equipment.
Energy Performance and Versatility
With a continuous power output of 3500 W at 40 °C (cos phi 1) and a peak load capacity of up to 6000 W (for 0.2 seconds), the AC Master 12/3500 handles motor starts and power tools. Its efficiency reaches 90 %, optimizing battery energy use. Output voltage is adjustable to 230/240 V AC (± 3 %) with selectable frequency of 50/60 Hz (± 0.1 %), and typical harmonic distortion below 3 %.
Advanced Features and System Integration
The inverter includes an AC transfer system that automatically switches between shore power or generator and battery supply. The energy-saving mode reduces consumption to less than 1.4 A at 12 V with no load. For higher power requirements or three-phase installations, the AC Master 2500/3500 allows parallel configurations of 2 to 15 units, or three-phase systems with up to 3 units. It is compatible with the MasterBus network for centralized control and monitoring, and includes a remote control option.
Robust Design and Safety
Measuring 283 x 496 x 128 mm (HxWxD) and weighing 10 kg, the unit is compact for hardwired installation with an EU Schuko connection. It operates in an ambient temperature range from -20 °C to 60 °C (derated above 35 °C) and features IP21 protection for horizontal wall mounting. Comprehensive protections against overheating, overload, short circuits, and battery voltage fluctuations (10.0 V to 16.0 V) are included, ensuring reliable operation.
