Product Details
Electrical Isolation
Provides electrical isolation between primary and secondary circuits, protecting sensitive audio components from power line surges, spikes, and DC offset. This significantly reduces the noise floor, revealing improved dynamics, imaging, and bass response in audio systems.
Stable Power Supply
The 1000VA power rating supports high current demands, ensuring dynamic audio amplifiers and equipment receive consistent, stable power even under peak loads without voltage drops.
Low EMI & RFI
The toroidal structure naturally confines the magnetic field, reducing electromagnetic interference that can degrade audio signal quality. An additional electrostatic shield 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 lengths, and mounting methods are fully customizable to meet specific application requirements.

FAQ
1 What is a 1000VA toroidal transformer used for?
Answer: 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 electrical isolation and noise filtering.
2 What does "1000VA" mean?
Answer: 1000VA (volt-ampere) is the apparent power rating. For resistive loads, 1000VA ≈ 1000W. For audio amplifiers with reactive loads, the transformer can deliver peak current 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?
Answer: Toroidal transformers offer several advantages: higher efficiency (≥94% vs. 85-90% for EI types) — reducing energy waste and heat; lower electromagnetic interference — the closed magnetic circuit minimizes stray magnetic fields; quieter operation — minimal mechanical hum and vibration; and smaller size and lighter weight for the same power rating.
4 How do I place an order or request custom specifications?
Answer: Please contact Shenzhen ZXY Electronics Co., Ltd. directly for pricing, availability, and ordering information. For custom specifications, please specify the desired input/output voltages, power rating, physical dimensions, mounting method, and quantity in your quotation request. The company offers OEM/ODM services with over 14 years of manufacturing experience in the transformer industry.
