The Alpha 2100 is a full legal power plus dummy load. In addition to continuously handling full legal power, it can handle up to 6000 Watts for up to 3 minutes. And that's where the dummy part ends—multi-color LED bar graph displays monitor forward power, reflected power and temperature, the temperature controlled forced-air system combats heat, a built-in serial data interface offers computer logging and control, and a full bypass shunt allows the unit to be kept in line at all times.
