1.2.2. Protection Circuits
There are several protection circuits used in the amplifier. They are activated when one or
more of next parameters exceed defined values or some unwanted occasion occurs.
•
VSWR too high
•
Anode current too high
•
Anode voltage error
•
Screen current too high
•
Screen voltage error
•
Grid current too high
•
Grid voltage error
•
Heating voltage error
•
Mistuning of PA
•
Temperature to high
•
Soft start for fuses protection
•
“switch-on blocking “ at opened amplifier
1.2.3. Features
The manufacturer implemented some of the company’s newest development results with most
wanted operating and safety features into this new model:
•
High level of protection
•
Memory for faults and warnings, easy maintenance
•
Automatic set-up anode current (BIAS) – no need to adjust manually after changing the
tube
•
Three programmable working modes of the centrifugal blower ( turbine ) + axial blower
•
Full QSK with silent relay
•
Many operational parameters to display
•
Easy transport due to detachable HV transformer
•
The smallest and lightest 2000 W Power Amplifier on the market
1.2.4. The Advantages of
•
Full compatibility with: ICOM, ELECRAFT, KENWOOD, TEN-TEC ORION, YAESU,
Icom,
transceive protocol using by MicroHAM devices ( CI-V output ), FLEX
Radios and Anan.
•
RF sensitive. The PA is usable also with radios, which doesn´t have CAT (automatic
frequency reading even if no CAT). Possibility of using BAND DATA information.
•
Automatic switching between bands. Automatic tuning within the band according to
segments.
•
Automatic switching of Band Pass Filter – BAND DATA output compatible with YAESU
radios (BCD code).
•
Automatic switching of Antenna switches. The maximum number of antennas is 10,
controlled by BCD output code.
•
Remote control possibility (remote software as accessory – no extra price)
