The LaMarche A31 Inverter is the ideal choice when AC power requirements are critical. Its ferroresonant transformer-based design and transistor switching provide an extremely reliable and high quality sine wave output .
The A31 has a wide range of standard features such as a sine wave output, voltage regulation, protection from AC-DC shorts, under/over-voltage conditions, input filtering and overload protection. It incorporates a DC input breaker and an automatic under/over-voltage shutdown circuit to protect the inverter. The A31 has a polarity indicator to tell you if the battery is connected incorrectly. The unit is equipped with an input filter pre-charge circuit, which includes an indicator to inform you that the inverter is ready for operation.
