5 banda equalizador gráfico usando LA3600 - Circuitos Eletrônicos e diagrama Eletrônica Projetos e Design. 0-30 VDC STABILIZED POWER SUPPLY WITH CURRENT CONTROL 0.002-3 A. As it is recommended start working by identifying the components and separating them in groups.
Place first of all the sockets for the ICs and the pins for the external connections and solder them in their places. Continue with the resistors. Remember to mound R7 at a certain distance from the printed circuit board as it tends to become quite hot, especially when the circuit is supplying heavy currents, and this could possibly damage the board. It is also advisable to mount R1 at a certain distance from the surface of the PCB as well. Continue with the capacitors observing the polarity of the electrolytic and finally solder in place the diodes and the transistors taking care not to overheat them and being at the same time very careful to align them correctly.
Electronics Lab - Projects. Power Supply Unit Multimeter. Technical Specifications - Characteristics single µC ATMEL ATmega8 used to handle all the multimetr functions; voltage range 0-30V; voltage measure resolution 10mV; current range 0-99A; current measure resolution 10mA (depend on current sense resistor value*); single, non isolated voltage supply; one side PCB; compact construction allowed to use multimetr as panel meter; well interaction with standard LCD based on HD44780 controller *Internal MULTIMETR resolution is given by equatin: resolution[mA] = 1/(R[om]*3.2) If internal resolution is worse than 10mA, MULTIMETER displays current with internal resolution, if better - with 10mA one.
In addition voltage drop on shunt resistor musn't exceed 2.4V, so R[om] should be less than 2.4/Imax[A] Construction Schematic.
