![]() ![]() The circuit of a self-made peak indicator of the output power for a load impedance of the amplifier equal to 4 ohms, provides an indication of the output power in the range of 1.5. ![]() The expansion of the dynamic range is achieved. The dynamic range of the measured powers is 43 dB (the extreme values of the recorded powers are 0.1 and 200 W). The output power indicator circuit with a logarithmic scale is made on the basis of the M476/1 pointer meter. build a LED level indicator with a logarithmic scale designed to control a line of 5 LEDs. The LED level indicator with a linear scale is designed to control a line of LEDs (scale). Other analogues: UAA180 (Telefunken), UL1890N (Unitra). The domestic analogue is the K1003PP1 microcircuit. What is a "signal level indicator" and where it is used, circuit diagrams of homemade devices that relate to the term "signal level indicator". Source - īelow are schematic diagrams and articles on the subject of "signal strength indicator" on the site on radio electronics and the radio hobby site. Transistor VT4 must be equipped with a powerful radiator. The circuit uses automatic adjustment of the charging current. The charger must be used with a transformer with a voltage on the secondary winding such that after rectification it is 12.6-15V / 4. Before the signal goes to input A1, its level is lowered using a divider consisting of resistors R5R7 and R6R8 for. The circuit has a normalized input, the input impedance is selected within 2 * 33 ohms so that the amplifier works with a natural load. The scheme of the set-top box - UMZCH amplifier for a CD player is shown in the figure. With R6 you can adjust the rotation speed. The basis of the device is a pulse-width modulation system made on the IC TL494, due to which the engine speed can be in the range from 0 to 100%. The figure shows a diagram of a simple 12V motor speed controller with a power of up to 150 watts. The microcircuit is available in a 5 pin package, the pins are electrically isolated from the microcircuit housing. MSK5012 has a high level of output voltage accuracy and stability. The regulator has a very low voltage drop (0.45V at 10A). ![]() The output voltage can be set using two resistors. ![]() MSK5012 is a highly reliable voltage regulator. ![]()
