Acknowledgment Thank you for purchasing Power linear amplifier TAJFUN 1000 432/144 from VH Electronics. During its productiom, we used the latest knowledge in the field of VHF Power amplifiers and the most advanced technology in the management, communication and display systems. We believe that our product will exceed your expectations and will be working properly to your satisfaction. - Page 3 I.3 Protection, measurements and display Protection PWR, REF, Temperature, Imax, Umax/Umin Control / Display Colour TFT display Measurements and display: Drain Current DC Voltage Output Power PWR Reflected Power REF Peak Power PEP Temperature I.4 Put into operation If your device was transported or stored in a cool or cold environment, it is necessary to unzip it first and let it dry in a warm enviroment (by doing this you will protect your device against a possible water condensation).
- Page 4 Insert a supplied power cord into the POWER. Then turn on the power switch. Initializing and control equipment starts. After a short time, the fans will start, initialize the TFT touch screen and display: Basic menu - “Home QSO“ , “Contest QSO“ By pressing an icon on the screen we select: I.4.1 Mode Home QSO This mode is suitable for the standard operation of the Home for the occasional QSO with less...
- Page 5 By pressing on the Icon, you can choose from the following views: o Standard o Bargraph o Peak o All values I.4.3 Standard It shows the performance of the Output Power - PWR, Reflected Power – REF, both appears in a bargraph and their values are represented in a numerical form + it shows the values of the Temperature, Current and Voltage Mode Rx Mode Tx...
- Page 6 I.4.6 All values It displays values as Standard. PWR PEP and REF PEP are displayed in the peak value and the maximum value are represented during the hold of the PTT (Tx mode) + it shows the values of the Coupler U PWR and U REF [mV] for servicing. I.5 Responding in excessing the parameters Alert / Block-Warning I.5.1 Output Power PWR Atlert - when crossing PWR above the set value (≥500W) it gets into a red bargraph, the...
- Page 7 I.5.2 Reflected Power REF Atlert - when crossing PWR above the set value (≥50W) it gets into a red bargraph, the numeric value turns red and the buzzer beeps Block - when crossing REF above critical value (≥55W) it declares "Warning" on the display and it blocks the LDMOS (Inhibit -5V), it turns the coax relay off and it blocks the PTT.
- Page 8 I.5.4 DC Voltage Atlert - when crossing DC Voltage above the set value (≥54V) the numeric value turns red and the buzzer beeps Block - when crossing DC Voltage above critical value (≥55V ) it declares "Warning" on the display and it blocks the LDMOS (Inhibit -5V), it turns the coax relay off and it blocks the PTT.
