![]() ![]() The power supply will always assert the maximum output voltage when starting or changing speeds, then revert to the programmed lower voltage after approximately 3 seconds. The motor requires much more torque at start up than it does once the platter is on speed by reducing the running voltage once the platter is moving, vibration and noise are greatly reduced. The fine adjustment is done in Frequency Calibration Mode, and there are separate adjustments for both 33 and 45 RPM settingsThe Falcon PSU also has a Voltage Calibration Mode that is used to adjust the output voltage the power supply reverts to, after the platter has reached operating speed. To compensate for these variables, the Falcon power supply allows you to precisely adjust the output frequency in 0.01 RPM steps. On belt drive turntables, there are many variables that can affect speed, such as belt tension and slippage, and even the position of the belt on the motor pulley. The Falcon also has a frequency calibration mode to precisely adjust the output for each speed in 0.01 RPM steps, 10x finer than the Music Hall Cruise Control or Pro-Ject Speed Box II.The output frequency of the Falcon power supply is extremely accurate. ![]() No user setup or intervention is needed plug the cable in between the tachometer and the power supply, and the Falcon immediately locks to the correct speed, even if speed offsets are selected, such as 33.4 RPM.During Normal Operation, the user can alter the speed in 0.1 RPM steps this is used primarily for "tempo" control. When connected to a RoadRunner tachometer (sold separately), the Falcon power supply automatically synchronizes its output frequency to maintain a constant speed on the turntable, within ☐.005 RPM. #A TURNTABLE AT ROTATIONAL SPEED 33 RPM SERIAL#The RoadRunner tachometer (sold separately) precisely measures the rotational speed of the turntable platter to 3 decimal places and provides the speed information to the power supply via a 3 wire serial cable. The Falcon is powerful enough to start up in either speed selection, so there is no need to start in 33 RPM, then switch to 45 RPM as in other units, all in a package about the size of a pack of cigarettes.The Falcon has a serial input for use with the optional RoadRunner digital turntable tachometer (sold separately). All of the operating parameters are stored in non-volatile memory and the device always power up with the last-used speed and frequency offset displayed. #A TURNTABLE AT ROTATIONAL SPEED 33 RPM MANUAL#DDS technology allows the Falcon power supply to generate signals with very high resolution, less than 35µHz steps.Read the product review Here.Read the Operators Manual Here.The Falcon power supply is extremely easy to use and set up. The Falcon uses Direct Digital Synthesis to create an extremely accurate and clean sine wave that improves motor speed stability, and allows the user to precisely adjust the turntable platter rotational speed. The output is 115VAC nominal, but can be used with lower voltage turntables by plugging the motor's wall adapter directly into the Falcon output. The Falcon PSU will work with any AC Synchronous motor that requires 5 Watts or less. This product is designed, manufactured and shipped from the USA.The Falcon Power Supply Unit from Phoenix Engineering is a microprocessor controlled digital AC power source, used for accurate speed control of a turntable motor. Is there a point 0691? This gives a 6.91 times 10 to the power minus four Newton meter is our talk.Item: 122056246450 Phoenix Engineering Falcon PSU Turntable Speed Controller for AC motors. Now we have I and all fossil simply substitute those values Well, we have done to the ball where minus two does mine. So we get minus 0.6 Line one radiant per second square. We get the minus three poor and 456 divided by time. So their final, angular, speedy zero When the turntables stops, the issue is a Megan or divided by 80 some student values. ![]() We know from the definition that the rate of change off anywhere speed is over. We can do that by applying 33 boy to apply, derided by 60 still sixties or seconds and this will give us 3.456 radiance per second. So first find the rotational solution where high is given from the problem Maeda we have is a 33 r p and meditation for minute so that worthless into or aliens per second. Thio rotational inertia times all four all far is over a traditional exploration. Why? First finding Ah, we know that dork is equal. ![]()
