The ED driver is configured to operate a broad range of resonant optical scanners and resonant optical choppers at their natural frequency. The ED driver amplifies the pickup coil signal from the resonant device and returns the amplified signal to the drive coil. This positive feedback loop is user controlled by an amplitude limiting trim pot. The ED driver also provides a monitor output square wave reference output signal and is amplitude control adjustable over a range of 5:1 min.

The ED type driver is available in the following configurations for driving SC Type Scanners and CH Type Choppers:

Model ED-M: A PC board mounted on standoffs
Model ED-P: A PC board used as a plug-in assembly
Model ED-110: An enclosed driver (3.25" × 2.12" × 1.12") for 110V ac operating
Model ED-220: An enclosed driver (3.25" × 2.12" × 1.12") for 220V ac operating

   Input Power     
   12V to 15V dc, 150 mA Max. 
   Frequency Range     
   5 Hz to 20 kHz 
   Amplitude Control     
   Adjustable over a range of 5:1 Min. 
   Monitor Output     
   A square wave reference output signal at J3 pin 1 (ED-110/220: pin M) 
   J1-Molex (Power):  P/N 22-23-2021 

   J2-Molex (I/O):  P/N 22-23-2041 

   J3-Molex (Monitor):  P/N 22-23-2021 
   Power Supply     
   An optional wall plug-in power supply is available 
   (PS-12-110 for 110V and PS-12-220 for 220V AC) 


TYPE [ED-110, ED-220, ED-M, ED-P]: Per customer's specifications.
