Highly Reliable Premium Copper Wire Toroidal Transformer for Low Heat Amplifiers Controls Audio System
Product Overview
100VA-1000VA 50/60Hz Single Phase Toroidal Transformer for Audio Amplifier
The Chipsen T110 toroidal transformer is a fully customizable low-noise power transformer built on a continuously wound CRGO (cold-rolled grain-oriented) silicon steel toroidal core with 100% copper windings. Its closed magnetic circuit keeps stray magnetic field, audible hum and EMI far below those of a comparable EI laminated transformer, making it the preferred choice for Hi-Fi audio amplifiers, medical and laboratory instruments, industrial control cabinets, LED lighting, UPS and isolation power supplies.
Chipsen is a Chinese magnetics manufacturer with in-house winding, vacuum impregnation and 100% electrical testing. Every T110 unit is produced under an ISO9001:2015 / ISO14001:2015 / IATF16949 quality system and can be supplied with UL/cUL, CQC, RoHS and REACH compliant material sets. OEM & ODM welcome — voltage, VA rating, lead-out, mounting and safety options are all made to order.
Key Advantages
Low noise & low hum — toroidal closed-loop core, vacuum varnish impregnated windings, virtually no mechanical buzz for audio-grade applications
Low stray magnetic field — typically 1/8 of an EI transformer of the same rating, so it can be mounted close to sensitive preamp or signal boards
High efficiency, low temperature rise — up to 95% efficiency, low no-load loss, compact and lightweight vs. EI types
Safe galvanic isolation — separated primary/secondary windings with optional electrostatic shield for control and isolation duty
Full customization — VA rating, single/dual secondary, tap voltages, flying leads or terminals, potting, and dimensional envelope all built to your drawing
Reliable supply — MTO production, 100% hi-pot / turns-ratio / no-load current testing before shipment
* Values above cover the standard customizable range. Final parameters follow the approved drawing / specification sheet.
Typical Applications
Audio: Hi-Fi power amplifiers, tube amplifiers, DAC and preamp linear power supplies, professional PA systems
Industrial control: control cabinets, PLC and instrument power, machine tool control transformers
Isolation & safety: 1:1 isolation transformers, medical and laboratory equipment
Lighting & power: LED drivers, halogen lighting, UPS, inverters and battery chargers
Others: broadcast equipment, telecom power, home appliances
Customization & OEM/ODM Service
Send us your input/output voltage, VA rating, dimension limits, lead length and safety requirements (or simply a drawing / sample), and our engineering team will return a proposal and quotation. Free electrical design review, sample lead time typically 7-10 working days, mass production 15-25 days depending on quantity. Private label and neutral packaging are supported.
Quality Control & Packaging
Incoming inspection of core, copper wire and insulation materials
Packing: anti-static bag + foam / carton partition, master carton on pallet; export-standard packaging
Shipping: by sea, air or express (DHL/FedEx/UPS); EXW, FOB, CIF and DDP terms available
Frequently Asked Questions
Q1: Why choose a toroidal transformer instead of an EI transformer for an audio amplifier?
A toroidal core has a continuous closed magnetic path, so it produces much lower stray magnetic field, lower audible hum and lower EMI, while offering higher efficiency and a smaller, lighter body at the same VA rating.
Q2: Can the T110 be made to my own voltage and VA rating?
Yes. Primary, secondary, taps, VA rating, wire length and mounting hardware are all customizable. Send your specification or drawing for a made-to-order design.
Q3: Are the windings full copper?
Yes. We use 100% enameled copper wire; CCA (copper-clad aluminum) is not used unless the customer specifically requires it.
Q4: What is the minimum order quantity?
MOQ is flexible for customized projects. Samples are available for evaluation before mass production.
Q5: Which certifications can you provide?
Production is covered by ISO9001:2015, ISO14001:2015 and IATF16949; material and safety compliance includes UL/cUL, CQC, RoHS and REACH. Test reports can be supplied with shipment.
Q6: How do I get a quotation?
Provide input voltage, output voltage/current or VA, quantity and any dimensional or safety constraints — we normally reply with a technical proposal and price within 24 hours.
