400V 230V Autotransformer 6500W 7200W 8000W Để Sạc Cọc

Tianyi toroidal transformers, manufactured and tested in compliance with EN61558. Designed and prepared for II class equipment. Suited for power supply circuitry of electric machines and electronics devices with low nonload losses and weight.We possessed use the most mordern machines, which guarantees the tightly wound coil and high electrical performance.

-Temperature fuse (130°) integrated in primary winding 

2. Technical Parameters

3. Standard Size

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.

(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.
