ButterflyMX Large Controller Enclosure - Fact Sheet

Product Data Sheet

The ButterflyMX Controller Enclosure – Large gives installers a standardized, professional solution for large multifamily, commercial, and multi-tenant access-control deployments. By consolidating controllers, power, distribution, and wiring organization into one secure enclosure, it reduces custom engineering, installation labor, electrical-room clutter, wiring errors, and future service calls while creating a cleaner, more consistent, and easier-to-maintain installation.

Designed for up to twenty doors, the enclosure includes a backplane, two integrated 24VDC, 10A power supply/chargers, two 16-output PTC or glass-fuse protected power distribution modules, and two voltage regulators. It accommodates up to ten ButterflyMX 2-Door Controllers, with an organized layout that simplifies controller mounting, field wiring, cable management, power distribution, troubleshooting, and ongoing service access
