| HL-2.5Kfx HF Amplifier
Features:
Description: The HL-2.5Kfx is the flagship of the Tokyo Hy-Power line of HF amplifiers. It is a full legal limit amplifier with a minimum output of 1.5kW (1.2 KW on 28 MHz), operating on bands from 160M-10M. The amplifier incorporates a pair of ARF 1500 RF Mosfets that are easily capable of supplying the required output power. It also includes a built-in power supply and operates with line voltages of 200v-250v ONLY. The operating voltage of the amplifier can be fine tuned (via transformer tap settings) to the line voltage present at the operator’s station for maximum efficiency. The HL- 2.5Kfx is designed to integrate fully with the Tokyo Hy-Power HC-1.5KAT Automatic Antenna Tuner. The HL-1.5KAT Tuner band switching will auto-synchronize to the 2.5Kfx amplifier band setting (manual or automatic mode), following whatever band is selected on the amplifier. Most third party automatic tuners will also function properly, when used with the HL-2.5Kfx. Of course manual tuners can also be used, though band selection and antenna tuning must be done manually and carefully by the operator. There is a front mounted LCD screen that displays current band setting. In addition the LCD will display any faults encountered by the amplifier. There are also two front mounted meters. One meter continually displays the power (forward) output. The second meter is selectable via the front mounted meter switch. It can display Power Reflected (Pr), Idle voltage to the MosFets (Vd), Transmitting Current of the MosFets, 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. To round out the front panel also installed are 4 LED indicators On Air, Fan Fault, Id/High current and Protection/Fault indicator. Rear controls include ALC adjustment control, DB15 switching band data connector, HL-1.5KAT Tuner Interface DIN socket, Exciter (Radio) input, antenna output, PTT keying line (STBY) RCA jack and a ALC RCA jack. The amplifier is QSK capable (50wpm+) using miniature high speed Panasonic relays for T/R switching. Due to its efficient externally mounted fan and an internal power supply, the HL-2.5Kfx is the smallest, lightest amplifier in its class. Included with the amplifier are the necessary cables to connect the unit to most Icom, Kenwood, and Yaesu radios. This will allow full automatic operation between the radio, amplifier, and antenna tuner. Other radios also have to be successfully integrated, though not currently supported by Tokyo Hy-Power, including Flex Radio, Elecraft, and TenTec Radios. Cables for these radios are available from third party sources. There are also some third party devices that will fully integrate the HL-2.5Kfx with any modern radio containing a RS-232 port. The amplifier will also synchronize 100% with the Fluid Motion SteppIr controller. The amplifier will follow the same band that is selected by the radio/controller. |
