The Simplex 565-247 is a reconditioned power supply controller board for the 4100 series. It mounts directly to the Simplex 636-341 power supply chassis. Together, the boards manage panel power distribution.
The 565-247 handles the supervisory and control logic for the power supply. Specifically, it sequences AC, DC, and battery sources. As a result, the panel maintains regulated DC to system components during normal operation and on backup.
How the Simplex 565-247 Fits the Panel
First, the 636-341 chassis carries the bulk power transformer and rectifier. Then, the 565-247 controller manages the regulation and supervision of those rails. Therefore, both boards must be present and matched for a working power subsystem. The 565-247 is sold reconditioned with a one-year warranty against board defects.

Important Compatibility Notes
The Simplex 4100-series spans multiple generations and revisions. For example, the 4100 / 4100U / 4100ES lineup uses different power supply assemblies across revs. Therefore, confirm your panel’s specific power supply assembly and chassis revision against the 565-247 before ordering. Our team can cross-reference your existing panel against the correct controller-board revision.
Important Note About Listings
Reconditioned panel boards typically lose factory listing certification. Specifically, UL 864 covers the original control unit as a system, and individual reconditioned boards do not carry standalone UL 268, UL 464, UL 864, or NFPA 72 listings. Therefore, the 565-247 should be installed by a qualified Simplex technician familiar with the panel’s listing context.
