Product Description
The ALTRONIX CORP TP1220 is a UL Listed plug-in transformer designed to provide low-voltage power conversion for security, access control, and related low-voltage systems. It connects directly to a standard AC outlet and steps down line voltage to a usable output for downstream devices and control equipment. The plug-in form factor eliminates the need for hardwired installation in many applications, making it a practical choice for technicians performing quick replacements or new installations where a compact power supply is required.
The TP1220 is suited for use in residential and light commercial environments where a plug-in transformer is specified for low-voltage alarm, access control, or auxiliary power applications. It is typically installed by low-voltage security technicians and electricians in panel rooms, utility spaces, or equipment closets. The UL listing indicates it has been evaluated to applicable safety standards for power supply equipment.
Key Features
- UL Listed for compliance with applicable safety standards
- Plug-in design for direct connection to a standard AC outlet
- Compact form factor suitable for low-voltage system applications
