US plug-in transformer 12V AC 20VA – TDC Power DA-20-12 power supply unit (120V US-Plug)

TDC Power DA-20-12 US Plug-in Transformer 12 V AC 20 VA Overview

The TDC Power DA-20-12 plug-in transformer is a compact AC/AC power adapter for operation on a 120 V power grid. It converts 120 V AC to 12 V AC, making it suitable for compatible low-voltage lighting, halogen lamps, and other electrical loads specifically designed for 12 V AC voltage.

With a power output of 20 VA and a directly integrated US Type A plug, the plug-in transformer is particularly suitable for applications in the USA and for compatible export devices. The compact plug-in design allows for straightforward power supply without the need for additional power cabling.

120 V AC input for US power grids

The US plug-in transformer for 120 V is specifically designed for such power grids and operates at a mains frequency of 50/60 Hz. Thanks to the integrated US Type A plug, the transformer can be operated directly from a suitable wall outlet.

12 V AC output voltage

On the output side, the transformer provides a stable 12 V AC alternating voltage. This makes it suitable for compatible low-voltage devices and lighting systems that specifically require a 12 V AC supply.

20 VA for low-voltage lighting and electronics

With an output of 20 VA, the power supply is particularly suitable for smaller low-voltage applications. Typical uses include halogen lighting, suitable AC LED systems, as well as compatible electronic devices and controllers.

Compact plug-in design

The direct plug design allows for space-saving and uncomplicated use. The power supply is plugged directly into a suitable US outlet, while the 12 V AC output is available via the existing connection cable.

Typical application areas

• Low-voltage lighting with 12 V AC
• Halogen lamps and halogen lighting systems
• Suitable 12 V AC LED systems
• Electronics and control devices with 12 V AC
• Replacement for compatible AC/AC plug-in transformers
• Export devices and applications for US power grids
