ED12DSS User Manual ver 1.00
The ED12DSS is the optimal driver for the new UNIBLITZ® N-CAS® DSS Shutter Series. This device will operate a single DSS shutter or a single NS series bi-stable shutter from a +12 to 24VDC power supply. (Bi-stable mode only requires power when switching the shutter’s state.) Once the input and output connector harnesses are connected, the user selects the open and close pulse duration - via the on-board 4-position piano switch - and connects a user supplied power supply. Once the shutter and the TTL input signal are connected together, the shutter’s exposure can be controlled via a TTL square pulse input. (Pulse duration determined exposure time.)
The ED12DSS can be easily integrated into OEM applications where a +12 to 24VDC power supply is available.
