Product Description

Product Description

As one of the best 500VA toroidal auto transformer suppliers, we provide high-quality solutions specifically designed for audio systems and precision electronic equipment. Our toroidal auto transformers are engineered to deliver stable voltage, ultra-low noise, and high efficiency, making them ideal for audio amplifiers, mixers, studio equipment, and Hi-Fi systems.

What Is a 500VA Toroidal Auto Transformer?

A 500VA toroidal auto transformer uses a ring-shaped magnetic core with a single shared winding for both input and output. Unlike isolated transformers, an auto transformer provides higher efficiency, smaller size, and lower cost, while maintaining excellent voltage regulation.

Thanks to the toroidal core structure, this transformer offers:
Minimal magnetic leakage
Very low vibration and hum
Smooth and stable voltage output
These characteristics are especially important in audio applications, where power quality directly affects sound performance.


Why Toroidal Auto Transformers Are Ideal for Audio Equipment

Audio systems are highly sensitive to electrical noise and voltage fluctuations. Our toroidal auto transformers are designed to meet these demands.

Ultra-Low Noise Operation

Toroidal core minimizes electromagnetic interference (EMI)
Reduces audible hum in amplifiers and speakers

High Efficiency & Stable Output

Rated power: 500VA
Low power loss ensures consistent voltage under load

Compact & Lightweight Design

Smaller footprint than EI-core transformers
Easy to integrate into audio cabinets and enclosures

Smooth Voltage Adjustment

Suitable for voltage matching and correction
Protects sensitive audio electronics from voltage stress

FAQ
 

Q 1. what's the payment term?  

A. We accept TT,30% deposit and 70% balance against copy of BL.

 Q 2. how's the delivery time ?

 Q 3. Tell me the standard of package?

A. For the small capacity, color box as inner package and carton as delivery package. For big capacity, use strong wooden case for protection.

 Q 4. What kind of material of transformer?

A. For servo type stabilizer, we have two types, one 100% copper and the other is copper with aluminum. It depends on your requirement . In fact, those two have no difference if normal work well. Only except the longlife. Copper is better and also higher price. For relay type stabilizer,we use toroid coils, the material is aluminum. comparing with square coils, toroidal coils with high efficiency.

 Q 5.Could you offer Form A or C/O ? 

A. It totally not a problem. We can prepare relative documents to forgin affairs office or other office to apply for this certificate.

A.Our logo is ZX. If your order,has good quantity,

it absolutly no problem to do OEM.

But you use our logo ZX will be high appreciated.

 Q 7.We want to know month capacity. 

A. It depends on which model.For example for relay type small capacity , month capacity can reach near 10000pcs   and big capacity near 2000pcs.

 Q 8.Where is your market?

A. Our products are popular inNorth America, South America, Eastern Europe, Southeast Asia, Africa, Oceania, Mid East, Eastern Asia, Western Europeand so on.Some of them are our regular customers and some of them are developing. We hope you can join us and make mutural benifit from our cooperation.

 Q 9. what kind of certificate you have ?
