Construiesc > Vand controler/protectie pentru amplificator HF LDMOS. Controlerul are la baza un MCU tip PIC18F458 ce asigura toate protectiile necesare in cazul depasirii puterii directe, reflectate, curentului DS, tensiunii de alimentare, temperatura, alegerea gresita a LPF-ului. PCB-ul controlerului este la aceeasi dimensiune cu display-ul de 5 inch in vederea amplasarii stack (dar poate fi amplasat si in alta parte din constructie). Interfatarea cu utilizatorul este facuta printr-un display NEXTION de 5 inch (dar poate fi folosit si unul de 7 inch). Firmware-ul pentru display asigura doar grafica, comenzile, afisarea si o parte din calculele necesare afisarii. MCU-ul se ocupa stric de protectii. Din controler se poate selecta banda de lucru a LPF-ului, dar exista si un decodor de banda (mod RF sau ICOM, la alegere din meniu). Controlerul are incorporat si un comutator pentru trei antene. Fiecare iesire de antena poate fi atribuita unei benzi, in mod automat. Default toate benzile sunt atribuite antenei nr. 1. Controlerul este construit in doua variante, pentru putere de 600W sau pentru 1200W. Pret pentru controler (fara display-ul nextion) este de 450 lei + transport prin curier. Se ofera controlerul complet, cu firmware in mcu, partial reglat (vor fi necesare ajustari fine pentru puterea directa si reflectata), firmware mcu si nextion, schema. Mai multe informatii/detalii pot oferi daca-mi scrieti un mail. Toate bune, 73! PS: in cursul construirii propriului amplificator (cu MRF300), din muuulta neatentie am emis (CW/FM) fara antena... controlerul si-a facut pe deplin datoria si a oprit alimentarea finalului. Un singur tranzistor am ars, asta pentru ca nu am facut corect reglajul pentru puterea reflectata! Nu am facut (inca) un test cu iesirea de antena in scurt... - Wed, 30 Oct 2024 17:54:21 +0000: Vand #V-224996 - Vand diverse becuri 1V-240V - Mica Publicitate YO - Anunturi
