DC Input Standalone Power for FOI Series PSQ-2920, PSQ-3920, PSQ-4920

PSQ-4920_sq
OVERVIEW

The PSQ-2920, PSQ-3920, and PSQ-4920 are compact DC power supplies which attach to and the provide operating voltage for FiberPlex’s FOI series isolators. They can power the FiberPlex FOI units with a 12-48 VDC external supply. These DC power supplies are not polarity sensitive, V+ and V- may be reversed for DC inputs. They are equipped with a resettable fuse to protect both the supply and the FOI. This power supply is not recommended for high security or TEMPEST applications. See the PSQ-2910, PSQ-3910 or PSQ-4910 for applications where RFI supression is critical. The FiberPlex PSQ supply has been updated to be easier to assemble. Previous versions of the PSQ required a separate bracket and multi-step process to attach the supply to an FOI. With this new design, you just pop on the back of the FOI and tighten two thumb screws. The all-enclosed design will also meet the most stringent safety standards. For more rugged mounting, wall mount adapters, WMA-2001 and WMA-3002 are available to secure the power supply and fiber optic isolator with screws. Both WMA-2001 and WMA-3002 are compatible with all PSQ and FOI series. The WMA-2001 has an optical patch, while the WMA-3002 does not. The wall mount adapter attaches to either a horizontal or vertical flat surface and provides a convenient termination point which protects both the fiber optic cable and the fiber optic isolator from damage.
