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.
