Product Description

Customized 60W Toroidal Transformer for Audio Amplifiers Input 230V Output 18V

1.Product Description

This customized 60W toroidal transformer is designed for high-performance audio amplifiers, featuring a 230V AC input and a stable 18V AC output for clean, efficient power delivery. Its high-grade silicon steel core and oxygen-free copper (OFC) windings ensure minimal energy loss (<5% regulation) and ultra-low noise (<20dB), making it ideal for Hi-Fi and professional audio systems. With ≥90% efficiency, double insulation, and a compact toroidal design, it provides reliable, vibration-free operation while reducing electromagnetic interference (EMI). Perfect for tube preamps, Class A/B amplifiers, and other sensitive audio applications demanding pristine power quality.

1.High-Efficiency Low-Noise Design

≥90% efficiency with <20dB hum for silent operation, minimizing interference in sensitive audio circuits.

Oxygen-free copper (OFC) windings and high-grade silicon steel core reduce losses and distortion.

2.Stable 18V Output for Audio Applications

Tight voltage regulation (<5% drop) ensures consistent power delivery, critical for amplifier performance.

Low no-load current (<30mA) enhances energy efficiency.

3.Robust & Reliable Construction

Double insulation (primary/secondary) and Class B (130°C) thermal rating for durability.

Compact toroidal design reduces EMI and mechanical vibration, ideal for Hi-Fi systems.

Function:

1. Voltage Conversion & Isolation

Converts 230V AC input to stable 18V AC output (dual/single secondary options).

Provides galvanic isolation between input/output, enhancing safety and noise rejection.

2. Clean Power Delivery for Audio

Low noise (<20dB): Minimizes hum/buzz in sensitive audio circuits (ideal for preamps, DACs, Class A/B amps).

Tight voltage regulation (±5%): Maintains stable output even under dynamic loads.

3. High-Efficiency Energy Transfer

≥90% efficiency with oxygen-free copper (OFC) windings and silicon steel core.

Low no-load current (<30mA): Reduces idle power waste.

4. Electromagnetic Interference (EMI) Suppression

Toroidal design inherently reduces magnetic stray fields vs. EI-core transformers.

Critical for avoiding signal degradation in high-fidelity audio systems.

5. Robust Thermal & Mechanical Performance

Class B (130°C) insulation: Handles sustained loads without overheating.

Vibration-resistant: Toroidal shape minimizes mechanical hum.
