Specification of customized prouducts
The UI90 Transformer is a specific type of laminated core power transformer, distinguished primarily by the shape and size designation ("90") of its magnetic core.
Core Construction (The "UI" Part):
The "UI" refers to the unique shape of the laminated steel core pieces. It consists of two distinct sets of laminations:
"U" Laminations: Shaped like the letter "U".
"I" Laminations: Shaped like the letter "I" (a straight bar).
These laminations are stacked alternately to form a closed magnetic circuit. The windings (coils) are typically pre-wound on a bobbin and then slid onto the central limb of the assembled "U" sections. The "I" sections are then inserted to complete the magnetic path.
Core Size (The "90" Part):
The number "90" designates the physical size of the core's central limb (the tongue width). A "90" core typically has a central limb width of approximately 90mm (or sometimes refers to a cross-sectional area associated with that size).
This size directly relates to the transformer's power handling capacity and its physical dimensions. A UI90 core is generally suitable for transformers in the medium power range, potentially handling several hundred VA to a few kVA (kilo Volt-Amperes), depending on design specifics like core material, stacking height, and operating frequency.
Key Characteristics & Advantages:
Ease of Manufacturing & Repair: The UI design allows for easy assembly and disassembly. Windings can be wound on a bobbin separately and then placed onto the core. This simplifies manufacturing and makes repairs or rewinding significantly easier compared to toroidal or some E-I core designs.
Mechanical Robustness: When properly clamped, the UI core structure provides good mechanical stability.
Good Magnetic Properties: Properly assembled with high-quality grain-oriented silicon steel laminations, UI cores offer efficient magnetic flux paths with low core losses (hysteresis and eddy current losses).
Cost-Effectiveness: The manufacturing simplicity often makes UI-core transformers cost-competitive for their power range.
Versatility: Can be designed for various input/output voltages, single-phase or three-phase configurations (though "UI90" usually implies single-phase), and different frequencies (50Hz/60Hz mains or higher frequencies).
Typical Applications:
Industrial Control Systems: Powering control panels, PLCs, motor starters, contactors, and relays.
Machinery: Providing isolated power supplies within machine tools, packaging equipment, etc.
Test & Measurement Equipment: Isolated power sources for benches or instruments.
Power Supplies: Used as the main isolation transformer in linear power supplies or as part of more complex systems.
Lighting: Powering low-voltage lighting systems (e.g., halogen) requiring isolation.
General Purpose Isolation: Wherever electrical isolation, voltage transformation, or safety isolation (SELV/PELV) is required from a mains supply.
Specifications (Typical Focus Areas - Specifics Vary by Manufacturer/Design):
Primary Voltage: Commonly 120V, 230V, 240V, 480V (mains voltages).
Secondary Voltage(s): Varies widely (e.g., 12V, 24V, 48V, 110V, 120V, etc.).
Power Rating (VA/kVA): Ranges based on core size/design (e.g., 300VA, 500VA, 1kVA, 2kVA).
Frequency: 50Hz, 60Hz, or 50/60Hz.
Insulation Class: Typically Class B (130°C), Class F (155°C), or Class H (180°C).
Cooling: Usually natural air convection (AN).
Mounting: Often chassis or base mounted with fixing holes.
Standards: Designed to meet relevant international safety and performance standards (e.g., IEC, EN, UL, CSA).

Other products
1. Q: Do you have a catalogue? Can you send me the catalogue to have a check of all your products?
A: Yes,we have product catalogue.Please contact us on line or send an Email to sending the catalogue.
2. Q: I need your price list of all your products, do you have a price list?
A: We do not have a price list of all of our products. Because we have so many items,and it's impossible to mark all of their price on a list.
And the price are always changing because of the producing cost.If you want to check any price of our products,please feel free to contact us.We will send offer to you soon!
3. Q: I can't find the product on your catalogue, can you make this product for me?
A: Our catalogue shows most of our products,but not all.So just let us know what product do you need,and how many do you want.We can also design and make a new mould to produce it.For your reference, making a ordinary mould will take about 35-45 days.
4. Q : Can you make customized products and customized packing?
A: Yes. We made a lot of customized products for our customer before(mainly wire harness).And we made many moulds for our customers already.
About customized packing, we can put your Logo or other info on the packing.There is no problem.Just have to point out that,it will cause some additional cost.
5. Q: Can you provide samples ? Are the samples free ?
A: Yes , we can provide samples.Normally, we provide 1-3pcs free samples for test or quality checking .
But you have to pay for the shipping cost . If you need many items, or need more qty for each item,we will charge for the samples.
6. Q: What kind of payment do you accept ? Can I pay RMB ?
A: We accept T/T(Wire transfer), Western Union and Paypal. Please be sure that we can receive the same amount of the Invoice. And you can pay money In RMB. No problem.
