The PLD-1S driver phase locks a resonant scanner (type SC, except for the subminiature scanners) to an external clock input signal. The system can be used as a "stand alone" unit or can be incorporated into an instrument or a system.
Although the scanner can be used in a large temperature range this driver is not recommended for use in temperature sensitive applications. To lock the scanner to an external clock signal you need to specify the exact clock frequency (to 4 decimal places). The phase relationship to the clock is factory set to customer's requirements (0° to 360°).

The PLD-1S-110 or PLD-1S-220 driver is a boxed driver for 110V or 220V (please specify). The driver has front panel controls for amplitude and phase and internal power supplies. The dimensions of the cased driver are: 12" × 10" × 3.8"
The PLD-1S-110/220 is a boxed driver with a line switch selector for operating from a line voltage of 110Vac or 220Vac.
The PLD-1S-PC driver is a printed circuit board level driver which requires an external +/-15V DC power supply.
