Tokyo HY-POWER HL-2500FX HF / 50MHz 1.5kW PEP Linear Amp. (1kW on 50MHz).
Typical output power is 1.5 kW PEP/SSB on HF (1kW on 50MHz) with the drive power of 85-90 W. The built-in band decoder will let you forget about the band setting when the amplifier is connected to your modern radio through such band data cables as ICOM CI-V, DC voltage (Yaesu and Elecraft K3), and RS-232C (Kenwood). These data cables are optional parts. The one that matches your radio should be purchased separately. However, auto band setting is also available for your convenience, even if band data cable for respective radio manufacturer is not connected, due to built-in fast counting frequency band discrimination system. Please note, however, that in this case semi break-in (CW) mode is recommended, as you may lose a fraction of very first dot , when fast full break-in mode is run.
Our solid-state broadband design engineers worked to make the HL-2500KFX, the lightest and most compact 1.5 kW amplifier in the industry, as the DC power supply section consists of switch-mode DC power supply accepting world voltage.
The amplifier is equipped with a newly developed band decoder. The amplifier’s decoder changes bands automatically as the data signal is received from the associated HF transceiver’s frequency bands.
The amplifier’s main PA section includes 6 high power MOS FET THP2933’s by Microsemi, resulting in 1.5 kW PEP (SSB max.). The amplifier’s broadband characteristics require no further tuning once the operating band is selected.
The amplifier allows operation in full break-in CW mode due to the use of the amplifier’s high- speed antenna relays (made by Panasonic).
With the unique duct structure design and the powerful blower fan, the aluminum heat sink block for RF PA module (and other components), are effectively cooled. The fan’s quiet operation allows for even the weakest DX signals to be heard.
The amp utilizes an advanced 16 bit MPU (microprocessor) to run the various high speed protection circuits such as overdrive, high antenna SWR, DC overvoltage, band mis-set etc.
This amplifier is compatible with AC 200 V to 250 V as well as AC 100V to 125V.
For the safety of the operator, an Interlock system is employed. The AC power is shut down if the top cover is removed, and the automated safety interlock is activated.
An analog multimeter allows the operator to monitor Pr (Reflected power), Vd (Drain voltage of power FET), Id (Drain current) and ALC voltage.
For future expansion, the amplifier rear panel is equipped with a control cable connection socket?(TUNER), this is for the upcoming model HC-1500AT, auto antenna tuner by Tokyo Hy-Power Labs. in 2013.
