HL-2500fx Linear Amplifier


Tokyo Hy-Power HL-2500fx Linear Amplifier


HF/50MHZ 1.5kW Linear Power Amplifier With RF POWER MOSFET THP2933

Tokyo Hy-Power HL-2500fx Linear Amplifier

The HL-2500fx, promoted by Tokyo Hy-Power for its light weight and compactness, is a 1.5-kW solid-state linear amplifier covering 160 through 6 meters. Modes include SSB, CW, and RTTY from drive power of up to 100 watts. Six THP2933 MOSFET transistors are at the amplifier's output. It is capable of full QSK (break-in) operation.

The unit measures 14.6 inches wide, 5.7 inches high, and 16.5 inches deep. Its front-mounted LCD screen displays current band setting and any faults encountered by the amplifier. There are also two front-mounted meters. One continually displays the power (forward) output. The second meter is selectable via the front-mounted meter switch to display Power Reflected (PR), idle voltage to the MOSFETS (VD), transmitting current of the MOSFETS (ID), and ALC voltage.

Additional front-mounted controls include an automatic/ manual band switch to select the mode of band switching, and a rotary band-selector switch to change the bands while in manual band-switch mode. Four LED indicators show: On Air, Fan Fault, Id/High current, and Protection/Fault indicator.
