- Page 2 The Falcon Power Supply Unit (PSU) is a microprocessor controlled digital regenerative AC power source used for accurate speed control of a turntable motor. The Falcon will work with any AC Synchronous motor that is 5W or less. The PSU uses Direct Digital Synthesis (DDS) 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.
- Page 3 Specifications Physical: Dimensions: 3.565" x 2.50" x 1.1875" Weight: 4 oz. Case: 1 piece Extruded Aluminium. Operating Modes: Standby, Sleep, Normal, Voltage Calibration, Frequency Calibration, Factory Default Programming Power Requirements: DC Supply 15VDC 600 mA nominal Normal mode; 20mA Standby; 5mA Sleep Output (5W Max): Voltage: 115V RMS nominal, adjustable from 85 to 115VAC...
- Page 4 Soft Start: Whenever the Falcon PSU exits Standby Mode, it starts the platter at ~20RPM and evenly ramps up the speed to prevent “burn out” on the belt. This greatly extends the belt life and improves long term speed stability.
- Page 5 Voltage Output Mode: Voltage Output Mode is used to adjust the output voltage the PSU reverts to after the platter has reached operating speed. 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.
- Page 6 (either 50Hz or 60 Hz operation) and which spindle to use (small or large). As shipped from the factory, the Falcon is set for the small spindle; extensive testing has shown this to be the most stable option with the least vibration.
- Page 7 Frequency Calibration Mode: Frequency Calibration Mode is used to fine tune the output frequency to compensate for belt tension and other variables that may cause the platter to rotate faster or slower than the indicated speed. Frequency Calibration Mode will adjust the base frequency in 0.01RPM steps within a range of ±1.0 RPM.
- Page 8 Factory Default Mode: To return the PSU operating parameters to the factory defaults, remove the power plug. Press and hold the Plus and Minus buttons while inserting the power plug. The display will show: Release both buttons and the display will show " don" to indicate factory default settings have been restored.
