1.Application: 
1). garden light 
2). LED underwater lamp 
3).LED Ground light
4).Outdoor power Supply
5).Audio sound field
6).Stage lighting


2.Advantages:
1).100% copper wire made
2).Toroidal style
3).plastic cover :ABS fire Material of withstand high temperatures 
4).Epoxy resin 
5).high performance insulation 
6).Anti-corrosion, waterproof performance

3.Equipment: 
Over 50 sets toroidal/annular/ ring coil winding machines, 3 EI type transformer lines, 2 sets of vacuum annealing furnaces, A set of nitrogen and hydrogen production equipment as below: 
. Automatic Winding Machine
. Semi-automatic Winding Machine
. Toroidal Winding Machine
. Insert Lamination Machine
. Wave Soldering Machine
. Plastic Termal Ultraviolet Machine
. Domino Ink Jet Printing Machine
 Transformer Multitester for High & Low Frequency
 Layer Insulation Withstand Voltage Tester
 
4.Warning 
Under no circumstances should both ends of the fixing bolt simultaneously contact the metal chassis or framework as this would create a potentially dangerous 'shorted-turn'. 

5.Certificate 
 We have abtained CE CQC RoHs UL ISO9001:2015,SGS and IEC approval. We guarantee quality is the first.

Test process:
1). No-load test (included no-load voltage,no load current and no load loss)
2). IInductive voltage test 
3). Load test (load voltage and temperature rise
4). Temperature rise test .
5). Insulated resistance 
6).Hi-pot test 
7).Leakage indutance test 
8).DC resistance test 
9).Surface inspection.


6.Note 
The above-mentioned toroidal transformer is frequently-used, we can also manufacture the products by customer design. And the specification is for reference, if has the change further, please take the material object as the standard. 

7.GREWIN'S Dimension : 
External diameter: 55mm-300mm, height :13mm-130mm, Efficiency: 75-98% 
we can design the appropriate products according to customers' requirments such as installation dimension, input and output voltage,power...etc.)
