DC Input Standalone Power for FOI Series

Model #: PSQ-2920 | PSQ-3920 | PSQ-4920

PSQ-2920 | PSQ-3920 | PSQ-4920
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-2909, PSQ-3909 or PSQ-4909 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. 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.
