What are the common applications of Pin Type Transformers?

Common Applications of Pin Type Transformers

1. Industrial Automation Systems
In automated equipment such as production lines and CNC machine tools, Pin Type Transformers provide stable power to control cabinets and servo drives, ensuring the reliability of high-precision motion control.
Through an efficient EI core structure, energy consumption is reduced and overall system operating efficiency is improved.
2. Power Control and Distribution
Used as a pre-power supply for frequency converters, soft starters, and power regulators, ensuring a clean voltage waveform and preventing electromagnetic interference from affecting sensitive equipment.
It possesses excellent electrical isolation performance, maintaining system safety during high load switching.
3. Precision Instruments and Measuring Equipment
In laboratory instruments, medical testing equipment, and high-precision sensors, Pin Type Transformers provide low-noise, low-drift power, meeting stringent requirements for power supply stability.
Its adaptability to high temperature and humidity environments allows it to maintain long-term reliable operation under harsh experimental conditions.
4. Communication and Signal Transmission Systems
Provides isolation and voltage regulation for power modules in fiber optic transceivers, wireless base stations, and data centers, ensuring signal integrity.
Low-power design contributes to improved overall system energy efficiency, meeting green environmental standards.

How to Choose the Appropriate Pin Type Transformer Voltage and Power?

1. Determine the Operating Voltage Range
First, select the corresponding secondary voltage specification based on the rated input voltage of the powered equipment to ensure the output voltage is within the equipment's allowable tolerance range.
Consider voltage margin during grid fluctuations and load changes, selecting a model with a certain voltage regulation margin to prevent voltage drops from causing equipment malfunctions.
2. Match Power Requirements
Calculate the required transformer's rated power based on the equipment's maximum power consumption (unit: VA or W). It is generally recommended to select a rated power 1.2–1.5 times the actual requirement to provide a safety margin and extend service life.
For loads with frequent start-stop cycles or instantaneous high current, the transformer's short-time overload capacity should be given special attention.
3. Assess Environmental Adaptability
If the ambient temperature exceeds 40°C or the humidity is high, select a model using high-temperature resistant insulation materials to ensure insulation performance is not affected.
For locations with special protection requirements (such as dustproofing and corrosion protection), consider installing a protective enclosure or selecting products that meet the corresponding industrial protection rating.
4. Check Certifications and Quality Standards
Confirm that the selected transformer has passed international quality and environmental certifications such as ISO9001 and RoHS to ensure the product meets safety and environmental requirements.
