Comelit 1441B VIP Power Supply
Overview
The Comelit 1441B is a 30W regulated power supply module designed to deliver stable 48VDC output for Comelit 1440 and 1456 intercom and door entry systems. It accepts standard North American (110Vac) or European (240Vac) mains input and mounts directly onto a standard DIN rail, making it ideal for central equipment racks, control rooms, or utility closets where multiple intercom units or expansion cards draw power. If you're upgrading or expanding a Comelit installation beyond what a single integrated power source can handle, the 1441B solves the capacity problem without requiring a separate UPS or external power distribution.
Compatibility
The 1441B powers Comelit 1440, 1456, and their regional variants (1440B, 1440S, 1440G, 1456B, 1456S, 1456G). Verify your existing system model and expansion module count before ordering—the 30W budget supports typical residential and small commercial multi-unit configurations, but oversized installations may require load analysis. Consult Comelit system documentation for your specific variant to confirm voltage and connector specifications.
Installation Notes
The unit is a 4-module DIN bar assembly (dimensions: 72 × 93 × 56 mm). Standard electrical connections apply—your installer will need to verify mains availability (110V or 240V switchable) and route 48VDC output to the main system control board or expansion backplane. No special tools beyond standard wire strippers and a Phillips screwdriver are required. Ensure adequate ventilation in the enclosure; the 30W dissipation is modest but non-zero in warm climates.
