Comelit 1395ul Transformer 110V 12V Ac 60 Va 4 Din Module

Product Description

The COMELIT 1395ul is a DIN-rail-mounted step-down transformer designed to power intercom and access control systems requiring a 12-volt AC secondary supply. It accepts a 110-volt primary input and delivers a 0-12V AC output rated at 60 VA for intermittent-duty applications. A built-in PTC thermistor provides internal overcurrent and thermal protection, automatically limiting current during fault conditions without requiring a manual reset under normal operation. This unit occupies 4 DIN modules of rail space, making it straightforward to integrate into standard electrical enclosures. Electricians and low-voltage technicians working on door entry or building intercom systems are the typical installers.

This transformer is suited for residential and light commercial intercom, video door entry, and access control panel installations where a reliable 12V AC supply is required within a DIN-rail distribution enclosure. Its intermittent-duty rating makes it appropriate for systems with cyclic load demands rather than continuous full-load draw. The 4-module DIN footprint fits standard 35mm DIN rail assemblies commonly found in structured wiring cabinets and electrical panels.

Key Features

• 110V primary input compatible with standard North American supply voltage
• 0-12V AC secondary output at 60 VA for intermittent-duty use
• Built-in PTC internal protection for automatic overcurrent and thermal limiting
• 4 DIN module form factor for integration into standard DIN-rail enclosures
• Compact profile suited for structured wiring cabinets and panel installations

Compatibility

Designed as an OEM-style power supply transformer for DIN-rail-based intercom, video door entry, and access control systems requiring a 12V AC secondary source at 60 VA.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage technician in accordance with applicable NEC requirements. De-energize the panel or enclosure before mounting or wiring the transformer. Verify that the connected load does not exceed the 60 VA intermittent rating to avoid triggering PTC protection. Secure the unit firmly to a 35mm DIN rail before making primary or secondary wiring connections.
