Inverters STUDER AJ - DC/AC

The series consist of pure sine wave inverters that convert a battery voltage to AC voltage for all AC appliances.

The series AJ  offer:

- a high and steady efficiency

- an outstanding overload capacity, thanks to the combined use of a toroidal transformer and a MOS power stage

- a digital regulation and microprocessor controlled

- an electrical supply to any kind of electrical appliance

- a complete internal protection of the inverter (overload, overheat, short-circuit, reverse polarity)

- an adjustable stand-by level on a large range and from a very low level (optional for AJ 275-350-400)
