EBS-1 Description     Hide

The Ameritron EBS-1 is an electronic bias system designed as an add-on for the AL-1200, 1500, and 82 amplifiers. It reduces heat by reducing quiescent current to very low values during periods when exciter output falls below 100 mW. The EBS-1H is compatible with other amplifiers, including amplifiers up to twenty kilowatts from MF to VHF. The EBS-1H has an internal adjustment for bias voltage and an internal regulated reference. The EBS-1 series features a remote detector board. The small, high impedance, detector board can be mounted near the source of RF, preventing the EBS-1 series from having any effect on input SWR. The switching and control board can be mounted any distance from the RF detector.
