Altronix Corp T2885D Open Frame Transformer 100VA 28V

Product Description

The ALTRONIX CORP T2885D is an open frame transformer rated at 100VA with a 28-volt AC output. Open frame construction means the core and windings are exposed, making this unit suited for panel mounting in enclosures where space is managed by the installer. It steps down standard line voltage to 28 volts AC to power low-voltage control circuits in security, access control, and building automation systems. Licensed electricians and low-voltage systems integrators are the typical installers. The 100VA rating provides adequate capacity for powering multiple control devices on a single secondary output.

This transformer is used in applications where a stable 28-volt AC supply is required for control panels, power supplies, and auxiliary devices. It fits residential and light commercial installations where open frame components are mounted inside a dedicated enclosure or electrical panel. The exposed frame allows for direct chassis mounting, simplifying integration into custom panel builds. It is well suited for security system panels, access control hardware, and similar low-voltage infrastructure requiring a reliable AC power source.

Key Features

• 100VA capacity supports multiple downstream low-voltage loads
• 28-volt AC secondary output for control circuit applications
• Open frame construction allows direct chassis or panel mounting
• Single unit per package for straightforward procurement

Compatibility

Designed as an OEM-style replacement or new-install transformer for low-voltage control panels and systems requiring a 28-volt AC, 100VA power source.

Installation Notes

Installation should be performed by a licensed electrician or qualified low-voltage systems technician in accordance with NEC requirements for transformer and control wiring. De-energize and lock out the primary supply before handling or wiring the transformer. Open frame units must be mounted inside a suitable enclosure to protect energized components from contact. Verify that the total connected load does not exceed the 100VA rating of the secondary winding.
