Operators manual falcon digital power supply unit.
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 accur...
Specifications physical: dimensions: 3.565" l x 2.50" w x 1.1875" h . 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 ...
Operating modes note: the turntable belt must be on the small pulley for proper operation. Standby mode: the psu will power up in standby mode as indicated by 3 dashes: sleep mode: while in standby mode, if no activity is detected for 5 min., the psu will revert to sleep mode and blank the display. ...
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, vibra...
To select the other speed output voltage, press and release the stby button. The display will show the newly selected speed, then revert to the output voltage for that speed selection. Increase or decrease the output voltage for the selected speed as above. When output voltage selections are complet...
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 ste...
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 hav...
Tachometer operation: the psu can be connected directly to the roadrunner digital turntable tachometer or roadrunner lite sensor via a 3 wire serial cable in order to synchronize its output with the direct measurement of the platter speed. Operation is completely automatic with no user intervention ...
