[QUOTE="Tururu, post: 1029071, member: 227656"] Currently the receivers [B]no longer have power regulators, have converters[/B], give them 12v and give what you want. [COLOR=#ff0000][B]With 12Vcc, they have no trouble giving 14V/18 Volts and 500mAmp.[/B][/COLOR] In general the motors (SG2100 / Dimo120 +) have peaks of 450mAmp., Then it has a stable consumption of 350mAmp. With coax low loss, the live is 1'13mm, even 1'33mm (a game bought years ago), without problems 60metros/83metros, some equipment allow to increase 1 Volt to compensate for long rolls of coax. [B]A regulator (LM317) needs 21-22Volts [/B]to work at 18V. Dissipating in heat the volts it does not give, [B]it literally burns the heatsink[/B] to 14Volts when [B]moving the motor[/B]. [B]A converter[/B], transforms by switching the input volts to whatever you want with a performance of [B]80-90%[/B], [B]with 500mAmp is cold[/B], only soldered the body to the plate/PCB, when they remove [B]3Amp [B](3000mAmp.) [/B]needs heatsink.[/B] -------- Actualmente los receptores ya [B]no tienen reguladores de alimentacion, tienen convertidores[/B], les das 12v y dan lo que quieras. [COLOR=#ff0000][B]Con 12Vcc, no tienen problemas para dar 14V/18 Voltios y 500mAmp. [/B][/COLOR] En general los motores (SG2100/Dimo120+) tienen picos de 450mAmp., luego tiene un consumo estable de 350mAmp. Con cable coaxial de bajas perdidas, el vivo es de 1'13mm, incluso 1'33mm (una partida que compre hace años), sin problemas 60metros/83metros, algunos equipos permiten subir 1 Voltio para compensar tiradas largas de cable coaxial. [B]Un regulador (LM317) necesita 21-22Voltios [/B]para trabajar a 18V. Disipando en calor los voltios que no da, [B]literalmente quema el disipador[/B] a 14Voltios al [B]mover el motor[/B]. [B]Un convertidor[/B], transforma por conmutacion los voltios de entrada a lo que quieras con un rendimiento del [B]80-90%, con 500mAmp esta frio[/B], solo soldado el cuerpo a la placa/PCB, cuando sacan [B]3Amp (3000mAmp.) necesita disipador[/B].
