Pin Type Transformer

A pin type transformer is a single-phase, low-frequency transformer with pin terminals, designed to be mounted directly on a circuit board or panel. Built on a laminated silicon-steel EI core with double (two-winding) copper coils, it converts mains voltage to the low voltage that control boards, instruments and small power supplies need, while keeping the input and output electrically isolated. The compact body fits tight layouts, and it is available as an open-frame unit or a potted unit, in vertical or horizontal mounting. Input and output voltages, pin layout and size are all made to your requirements.

Materials and Construction

  1. Full copper enameled wire: low resistivity and good fatigue resistance allow tight, compact coils that carry current without running hot.
  2. Silicon steel laminations: high magnetic induction lets a small core do its job, with low iron loss to keep efficiency up.
  3. Steel mounting bracket (iron bridge): a new, durable steel frame that gives the small body a solid, stable base on the board or panel.

News&Events
Pin Type Transformer Industry knowledge

The Pin Type Transformer is a high-efficiency EI-core transformer built by Ningbo Chuangbiao Electronic Technology Co., Ltd. for industrial automation, power control, and precision instrument applications. Operating as a transformer factory that focuses on EI transformer factory output, Ningbo Chuangbiao Electronic Technology Co., Ltd. runs its low-frequency transformer factory around this pin-mount format because it pairs stable voltage output with the compact footprint that panel-mounted control equipment needs. This article sets out exactly what the Pin Type Transformer is built from, how it performs, and how Ningbo Chuangbiao Electronic Technology Co., Ltd. supports buyers sourcing this component as a low frequency factory serving industrial customers.

01EI-Type Core Design and Power Conversion

Ningbo Chuangbiao Electronic Technology Co., Ltd. builds the Pin Type Transformer around a classic EI-type core structure. This core geometry increases magnetic flux density and reduces energy loss, which lets the transformer factory deliver more efficient power conversion within the same physical volume compared with a less refined core layout. The result is a unit that holds stable operation under different loads while keeping voltage output clean.

EI-Type Core

Raises magnetic flux density and lowers energy loss for more efficient conversion in the same volume.

Stable Output

Operates reliably under different loads while keeping voltage output clean and consistent.

Electrical Isolation

Prevents external electromagnetic interference and voltage fluctuations from reaching connected equipment.

02Efficiency, Load Handling and Thermal Resistance

During operation, the Pin Type Transformer maintains low energy loss while providing efficient power conversion. Its compact design outputs stable voltage across various load requirements, keeping energy efficiency high rather than trading efficiency away for size. Ningbo Chuangbiao Electronic Technology Co., Ltd. also builds the unit with high-temperature-resistant insulation materials, so it continues operating in high-temperature and humid conditions where less durable insulation would fail early.

Low energy loss operation

Efficient power conversion is maintained throughout normal operation, avoiding unnecessary heat build-up.

Compact voltage stability

The compact build still outputs stable voltage across varying load requirements.

High-temperature insulation

Insulation materials resist high temperature and humidity for long-term stable operation.

Durability in complex environments

High durability supports use in demanding environments without shortening service life.

03Quality Control and Certification

Every Pin Type Transformer built by Ningbo Chuangbiao Electronic Technology Co., Ltd. passes strict quality inspection and testing before it leaves the factory. Production follows the ISO 9001 quality management system, and the product also complies with ROHS environmental protection certification, matching international environmental standards for buyers importing into regulated markets.
