Overview

The Comelit 909032059 is a 50W, 3-Amp 12Vdc regulated power supply designed for access control and video intercom installations requiring stable auxiliary DC power. DIN-rail mount form factor fits standard electrical enclosures in technical closets, equipment racks, or electrical rooms. Pre-wired battery output cables simplify backup integration for systems needing uninterrupted power during mains failure — common in residential and light commercial video door station deployments.

Compatibility

Integrates with Comelit intercom systems and infrastructure requiring 12Vdc auxiliary power. Suitable for powering Comelit video door stations, access control modules, and networked intercom devices in residential and commercial buildings. Check your specific Comelit system documentation to confirm 12Vdc input requirements before ordering.

Installation Notes

Delivers stable 12Vdc output with 80% efficiency — reduces thermal load in enclosures compared to lower-efficiency units. Pre-wired battery output connectors eliminate custom cable fabrication. Mounted on standard DIN rail (35mm profile) — no special tools required. CEC Level 6 rated, meaning power consumption remains low even under partial load, important for installations where the PSU runs continuously. Ensure adequate clearance around the unit for convection cooling; do not stack or block ventilation slots. Compatible with standard 12Vdc backup batteries rated for auxiliary power applications.
