220V 50HZ With Base Plate Toroidal Transformer for Audio Amplifiers Dual AC

1.Product Description

I. Core Features

High Efficiency and Low Loss

The ring-shaped magnetic core structure minimizes magnetic resistance and leakage, achieving efficiency of over 90% and reducing energy waste, making it ideal for high-fidelity audio equipment.

Designed for 50Hz power frequency, it is compatible with domestic standard voltage (220V) and operates stably.

Low Noise and Interference Resistance

Symmetrically distributed ring coils minimize electromagnetic interference (EMI), preventing noise interference with audio signals and improving the signal-to-noise ratio (SNR).

Metal base mounting reduces mechanical vibration noise, making it suitable for environments with high silence requirements.

Dual AC Output Design

Provides two independent AC outputs, enabling simultaneous power supply to both the preamp (e.g., operational amplifier) and power amplifier circuits, supporting positive/negative power supply architectures (such as OCL amplifiers).

Flexible output voltage (common dual 12V/15V/18V, etc.) to accommodate different circuit requirements.

Heat Dissipation and Durability

The ring structure provides a large heat dissipation area with low temperature rise. Combined with the base mounting, it facilitates airflow and extends service life.

High-quality insulating materials and copper wire windings ensure high-temperature resistance and moisture protection, suitable for long-term operation.

Compact Installation

The ring-shaped design saves space, and the base includes screw holes for easy mounting inside a chassis, simplifying wiring.

II. Typical Application Scenarios

Hi-Fi Audio Amplifiers

Provides a clean power supply for Class AB/D amplifiers, reducing background noise and ensuring audio quality (e.g., DIY amplifiers, tube amplifiers).

Professional Audio Equipment

Used in audio processing equipment requiring dual power supply, such as mixing consoles, equalizers, and electronic crossovers.

Tube Amplifiers

High-voltage AC output compatible with tube circuits (requires rectification and filtering).

Laboratory Power Supply

Serves as a pre-stage transformer for linear regulated power supplies, providing adjustable DC output voltage.
