Alpha Communications T1640 Plug-in Transformer 16VAC 40VA

Product Description

The ALPHA COMMUNICATIONS T1640 is a plug-in power transformer rated at 16 volts AC and 40 volt-amperes (VA). It steps down standard line voltage to a low-voltage AC output, supplying stable power to intercom systems and associated accessories. The T1640 connects directly to a standard outlet, eliminating the need for a hardwired transformer installation. It is typically installed by low-voltage technicians, security installers, or experienced electricians working on intercom and door communication systems.

The T1640 is designed for use in residential and light commercial intercom system installations. It provides the low-voltage AC power required to drive intercom panels, door stations, and related accessories. Its plug-in form factor makes it well suited for retrofit installations and locations where a dedicated transformer enclosure is not practical or required.

Key Features

• 16 volts AC output for direct compatibility with standard low-voltage intercom system requirements
• 40 VA capacity supports intercom panels and connected door station accessories
• Plug-in design installs directly to a standard wall outlet with no hardwiring required
• Compact form factor suited for retrofit and new intercom installations
• Sold as individual unit for single-system applications

Compatibility

Designed as an OEM-style plug-in transformer for low-voltage intercom systems and accessories requiring a 16-volt AC, 40 VA power source.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed electrician in accordance with applicable NEC requirements for low-voltage power supplies. Disconnect or unplug the transformer before making any wiring connections to the intercom system. Verify that the total VA load of all connected devices does not exceed the 40 VA rating of the transformer. Inspect the outlet and wiring for proper grounding before plugging in the unit.
