Product detail
Galvanic Isolation
Provides electrical isolation between primary and secondary circuits, protecting sensitive audio components from power line surges, spikes, and DC offset . This significantly lowers the noise floor, revealing improved dynamics, imaging, and bass response in audio systems.
Stable Power Delivery
The 1000VA power rating supports high-current demands, ensuring dynamic audio amplifiers and equipment receive consistent, stable power without voltage sag—even during peak loads.
Low EMI & RFI
The toroidal structure naturally confines magnetic fields, reducing electromagnetic interference that can degrade audio signal quality. Additional electrostatic shielding between primary and secondary windings further attenuates common-mode and differential-mode noise.
Customizable Configurations
Input and output voltages, power ratings (50VA–20,000VA), lead wire lengths, and mounting styles can be fully customized to meet specific application requirements

faqs
1
What is the 1000VA Toroidal Transformer used for?
A: This transformer is a high-power, low-noise power conversion component designed for audio amplifiers, professional audio equipment, industrial controls, medical devices, and power supplies. It steps down high-voltage AC (110V/220V/230V) to lower voltages (12V/24V/55V) while providing galvanic isolation and noise filtering.
2
What does "1000VA" mean?
A: 1000VA (volt-amperes) is the apparent power rating. For resistive loads, 1000VA ≈ 1000W. For audio amplifiers with reactive loads, the transformer can deliver peak currents exceeding its rated capacity due to its low output impedance and high instantaneous current capability.
3
Why choose a toroidal transformer over a traditional EI transformer?
A: Toroidal transformers offer several advantages:
Higher efficiency (≥94% vs. 85-90% for EI) – reducing energy waste and heat
Lower electromagnetic interference – the closed magnetic circuit minimizes stray fields
Quieter operation – minimal mechanical hum and vibration
Compact size and lighter weight for the same power rating
