Mastervolt AC Master 12/2000 US Inverter - 120 V

The Mastervolt AC Master 12/2000 US (120V) inverter converts a 12V battery voltage into pure sine wave 120V AC power. It is ideal for powering sensitive electronic equipment, lighting, electric cooking appliances, or electric tools aboard vehicles or boats.

This inverter can provide a continuous output of 2000 W at ambient temperatures of 25 °C and 40 °C. It also offers peak load capabilities of up to 2300 W for 1 minute and 3500 W for 1 second.

The output voltage is 120 V AC (± 3%) and the frequency is selectable between 50 or 60 Hz (± 0.5%). These parameters can be adjusted via the DIP switches.

The inverter dimensions are 248 x 443 x 83 mm (9.8 x 17.4 x 3.3 in) and it weighs 5.24 kg (11.5 lb).

The inverter operates with a nominal battery voltage of 12V. It is recommended to use a battery with a minimum capacity of 200 Ah to ensure optimal operation.

For a secure installation, the ground point of the AC Master chassis must be connected to the central ground point of the vehicle or boat. It is crucial never to use the device in an area where there is a risk of gas or dust explosions.

The inverter is equipped with protections against battery voltages that are too low or too high:

It shuts down if battery voltage drops to 10.5 V and restarts at 12.5 V. It shuts down if battery voltage rises to 16.5 V and restarts at 14.5 V.

The power-saving mode can be enabled via DIP switch 4. In this mode, the no-load power consumption is reduced to less than 0.1 A at 12 V, compared to less than 1.8 A in normal mode. The power-saving trigger threshold is adjustable between 20 VA (minimum) and 110 VA (maximum).

For the 12V 2000W model, the minimum recommended DC cable cross-section is 70 mm² (2/0 AWG).

Yes, the Mastervolt AC Master 12/2000 US (120V) inverter has full galvanic isolation between input and output, which improves safety and reduces interference.

The inverter can operate within an ambient temperature range of -20°C to 60°C. However, power reduction (derating) is applied above 40°C, with a capacity of 40% at 60°C.

The Mastervolt AC Master 12/2000 US (120V) inverter has a high efficiency of 92%, minimizing energy loss during DC to AC conversion.

Yes, the inverter produces a pure sine wave output, making it perfectly suited for powering sensitive electronic equipment and ensuring stable operation without risk of damage.

In case of overload (indicated by a red LED light), the connected load must be reduced and/or the AC wiring checked for possible short circuits. The inverter must then be manually reset by turning off and then back on the main switch.

Mastervolt disclaims all liability for consequential damages resulting from the use of the AC Master. This means the user is responsible for ensuring the device is used in accordance with instructions and safety standards to avoid indirect damage.
