A 12V 1A transformer is an electrical device designed to convert higher AC voltage from the mains (typically 220V or 120V) down to 12 volts AC with a maximum current output of 1 ampere. These transformers are commonly used for applications requiring 12V AC power, such as LED lighting, small motors, or certain low-power electronic circuits.

Key Specifications

• Input Voltage: 220V AC or 120V AC (depending on the region)
• Output Voltage: 12V AC
• Output Current: 1 Amp (maximum)
• Power Rating: 12 Watts (based on 12V x 1A)

Features

• Step-Down Conversion: Lowers high input voltage to a safe 12V output suitable for many electronic devices.
• AC to AC Transformation: Provides an AC output voltage, which can be further rectified if DC power is required.
• Safety: Isolation from high voltage through transformer windings, reducing shock risk.
• Low Ripple: Suitable for circuits requiring stable power with minimal ripple and noise.

Applications

• LED Lighting Systems: Low-power lighting circuits or LED strip lights.
• Home Appliances: Small appliances or electronic devices that run on 12V AC.
• Audio and Signal Equipment: Provides stable AC power for certain audio or signal processing devices.
