LA-250V - RM Italy LA-250V

The LA-250 is a 200 W 140-150MHz amplifier, at 1 to 20 W input (13.6V 30A). It uses 4 Mitsubishi RD70 Mosfets mounted on a copper heat spreader (200x60x3mm). It is available in two versions one with and one without top mounted fans. There is an external PTT input but it can be used also without due to the built-in HF-VOX.

The front panel features an LC Display which shows input power, output power, heat sink temp and output VSWR. There is the ability to change the intensity of the backlight. The CPU keeps an eye on input power, temperature and VSWR and will if necessary disable the amplifier from transmitting if there is fault. Any errors will also be recorded and will be available for later recall for diagnostic purposes by either the manufacturer or his distributors. Weight is approximately 4kg.

Dimensions are approximately 240x420x70 mm for the non fan version and an extra 10 mm of height, 80mm, for the fan version. The LA-250/LA-250V has a large DC connector, a suitable plug is included. You will need a large gauge DC cable additionally (at least 2.5mm² or more).
