I'm providing my own power to the OEM drive board. What are specs for the necessary power cord and power supply?
|
The power connector/cord we use is a Mouser Electronics #172-4201 (mouser.com / tel. 800-346-6873). Ref. Shutter Pwr Cable - Mouser 172-4201.pdf
The recommended power supply is 12VDC, regulated, 3 Amp (providing some "reserve" over the 2.5A max load).
|
I'm using the OEM board with TTL control. What are the proper DIP switch settings?
|
For direct TTL control of shutter "ON" time, DIP switches DS-1 & DS-2 should be ON. DS-3 should be OFF. On-board timer pot R3 should be set to it's minimum value (full CCW). Maintain the TTL pulse as long as required to get desired shutter timing.
For on-board control of shutter "ON" time, all DIP switches should be ON. Initiate the shutter drive with a short TTL pulse (i.e., 20mS). Set on-board timer pots as needed to get desired shutter timing.
Notes - The shutter will not actuate if DS-2 and DS-3 are both OFF. See Operating Instructions sheet #25164B for more complete information.
|
When the shutter is closed, is the transmission zero?
|
For standard (black-painted metal) shutter blades, the transmission is essentially zero.
|
What is the light power that can safely be incident on the closed shutter without affecting its performance?
|
Maximum allowable light level will depend on many factors (wavelength, duration, blade material, blade coating, and environmental conditions), generally limited by coating damage and/or warping of shutter blades. Although we do not rate shutters for specific light levels, we can provide sample blades for application-specific testing by customers. Contact Melles Griot Applications Engineer for sample blade arrangements.
|
How does the X synchronization work?
|
When the shutter blades are fully open (or fully closed for a normally open shutter); a dry contact is made with the X-synchronization, which provides electrical continuity.
|
May I use a lower DC signal than the recommended 4X the rate solenoid voltage to open or close the shutter?
|
We recommend only using the recommended 4X voltage pulse for 20mS; Using any lesser voltage will result in less reliable shutter actuation.

|
What is the laser damage threshold for the shutters blades?
|
We do not have a documented laser damage threshold for our Spring-Steel Blades with a Teflon-impregnated black matte finish. If this is a concern for your application Melles Griot will send you a shutter blade for testing.
