Tokyo Hy-Power HL-2.5Kfx Hf 1.8-28 MHz 1.5 kW 250W Solid State Linear Amplifier

  
Tokyo Hy-Power HL-2.5Kfx Hf 1.8-28 MHz 1.5 kW 250W Solid State Linear Amplifier. Features: -Small Footprint -Light weight- lightest 1.5kW amplifier in its class -Internal Power Supply -Automatic band change when used with most modern transceivers Icom, Kenwood and Yaesu -Amplifier incorporates an advanced 16bit Microprocessor that controls all the functions of the amplifier, including the protection circuits. Lower cost in replacing finals compared to replacing tubes in tube-type amplifiers.

When properly configured truly ONE BUTTON OPERATION. No tuning, waiting, or selecting bandsJust select a frequency and transmit!

The HL-2.5Kfx was the flagship amplifier of the THP line of HF amplifiers for 5 Years and was to be replaced in 2014 by the HL-2500Fx. 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 very first 2.5Kfx were actually developed in a semi kit form and later a early production model appeared that looked slightly different from the final model. The amplifier incorporates a pair of ARF 1500 RF Mosfets that are easily capable of supplying the required output power, they are mounted on a very large solid copper heatsink. 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 operators station for maximum efficiency. It should be noted that in late 2011 THP reworked parts of the amplifier and changed one of the boards. The firmware was upgraded to Ver 1.5E This upgrade made the amplifier literally bullet proof and was tested by shorting the output with a screwdriver at full output and no damage occurred. THP also limited the 10M output to approx. 1Kw as the 10M band was too stressful on the mosfets when some hams tried to use them at legal limit on 10M.

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.

Power Requirement: 200VAC-250VAC, 50/60Hz 3000VA Cooling Method: Forced Air Cooling T/R Switching: Miniature High Speed Relays (Panasonic / 5-6 ms) Size: 12.8W x 5.7H x 15.9D Weight: 57.3 lbs Excellent pre-owned condition with little to no signs of wear. Original box and owners manual included. Includes power cable, but no other connecting cables.
