Plug-in transformer adapter 120V AC → 12V AC – 20VA, USA version (Class 2)

Sompex US Plug-in Transformer 120 V to 12 V AC 20 VA at a Glance

The US plug-in transformer with 120 V AC to 12 V AC is a compact AC/AC transformer for suitable low-voltage lighting and electronic devices. With an output power of 20 VA and an output current of 1.67 A, the black plug adapter is particularly suitable for corresponding 12 V AC applications on the US power grid.

The direct plug-in design allows for uncomplicated connection to a suitable US wall outlet. Thanks to the Class 2 design, the transformer is suitable for various low-voltage indoor applications, including halogen systems and compatible 12 V AC LED lights.

120 V AC input for US power grids

The US plug-in transformer is designed for an input voltage of 120 V AC at 60 Hz. This makes it suitable for corresponding applications in the USA and other installations with compatible mains voltage.

12 V AC with 1.67 A output current

On the secondary side, the transformer provides 12 V AC alternating voltage at 1.67 A. The maximum output power is 20 VA and is intended for appropriately designed low-voltage consumers.

Class 2 design for low-voltage applications

The plug-in transformer is designed as a Class 2 transformer and is suitable for compatible low-voltage lighting and electronic applications. This particularly includes halogen systems and LED lights that are explicitly designed for a 12 V AC supply.

Compact design with US plug

The black plastic housing has dimensions of 70 × 50 × 70 mm. The mains connection is made directly via the integrated US plug, while a connection socket is available on the secondary side.

Typical areas of application

• Low-voltage lighting with 12 V AC
• Halogen lighting systems
• Suitable 12 V AC LED lights
• Electronics and control devices with 12 V AC
• Replacement for compatible AC/AC plug-in transformers
• US and export applications

Important note

The plug-in transformer is intended exclusively for a mains voltage of 120 V AC and must not be operated directly on a European 230 V power grid.

The output provides 12 V AC alternating voltage and is therefore not suitable for consumers that explicitly require 12 V DC direct voltage. The maximum output power of 20 VA must not be exceeded. The transformer is intended exclusively for indoor use.
