Note: The standard input is dual 110V ac windings, parallel connected for 110V ac, or series for 220V ac. As for larger power size, do not hesitate to request the details from us.

4. Custom Design

Do not see what you're looking from our standard catalog, just send inquiry to assist you in designing a custom toroidal transformer for your project. Refer to the following information to get started.

Toroidal X5

 

 

(1) Insulation System - Our standard is Ul approved class B (130°). Options include UL class A (105°), class F (155°), class H (180°), or to suit.

(2) Temperature Rise - Typically we design for 60° rise, but can be application dependant. This yields the size and regulation specs listed in the standard line.

(3) Input Sides - As these are application specific, we have several traditional input configurations for both 50Hz and 60Hz, which are described in our standard line. Optionally, we can design for 10 - 400Hz using goss cores, and will select appropriate materials, as higher F is needed.

(4) Power Size - No factory limits are implied, but typically we can design and manufacture single-phase toroids up to 10000VA.

(5) Duty Cycle - Significant reductions in transformer size and weight may be realized in most cases where the transformer is loaded intermittently. Duty cycle is an important design consideration.

Operating Process

Once the specification and quote are approved, sampling will be immediately operated. Prototypes are prepared by our sample department, under engineering supervision, subject to production's standard process control and inspection. After extensive testing for conformity to specifications and safety agency requirements, the design is reviewed, and usually the samples are shipped within one week.

 

1. Materials Purchasing

We select materials that are listed by the applicable safety agencies. All incoming material is inspected. Complete vendor histories are maintained by the quality assurance department for analysis of supplier performance.

2. Manufacturing procedure

(1) Core from 0.23mm thick silicon steel Japanese materials 23Q115 edges are ground smooth

(2) Core protection from 4 layers polyester films (2 layers with 50% overlap)

(3) Primary winding wire ( polyesterimid enameled QZY 180) and temperature class 180°

(4) Primary leads from type UL1672 double insulation for 600V voltage and 105° temperature

(5) Primary to secondary insulation from 6 layers polyester films (3 layers with 50% overlap)

(6) Secondary winding wire ( polyesterimid enameled QZY 180) and temperature class 180°

(7) Secondary leads from type UL1015 for 600V voltage and 105° temperature

(8) Final insulation from 2 layers polyester films (1 layers with 50% overlap)
