Product Description
We have passed ISO9001:2015,CE,SGS approval and IEC report
GW-I Series: High Quality Encapsulated Toroidal Transformers with Pins
Remark:
A. D refers to the volume of a corresponding transformer, which will be replaced with a digit. For the transformer with a single winding, the corresponding max. volume can be reached; for the transformer with two or more windings, the corresponding volume will be reduced properly.
B. Being a tendency of future pin transformer, it is applide with our best self-made toroidal core (Po≤0.9W/Kg) in the result of High Efficiency, Low Power Loss and Low Temperature-rise to be Green, Energy-saving & Environment-friendly.
C. Attributed to our Patent Technology, excluding the pins distribution mentioned above, the pins distribution can be freely adjusted by following customer's advice.
D. Nice Appearance, Small Size, Moisture Proof & Mould Prevention.
E. Pins Quantity can be reduced or increased based on your requirement.
Minature Transformers:
The dimension of the Control Transformer Usage &Toroidal Coil Structure step-up auto-transformator 380V to 200V
The Partial List of GW-B Series Toroidal Transformers with Cable and Mounting Holes:
1. Installation:
Horizontal (non-conventional-type base plate), sunk, side type, and bridge.
2.Application:
Especially low-hum and low-dispersing construction
Low-level of induction
High-grade design casing possible
Statically shield winding and magnetical shield winding optional
Be used widely such as audio equipment,communication,new energy areas,Electrical control,Cable TV network etc.
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.
Application:
Application:
1). audio equipment
2). electric control
3). computer
4).instrument
5).telecommunications
6).high-end and middle-end vedio etc
