Encapsulated Transformers | Custom Encapsulated Transformer Manufacturer

Encapsulated transformers adopt epoxy full‑potting technology to achieve dust‑proof, moisture‑proof and anti‑vibration performance. Our custom encapsulated low frequency transformer series mainly includes encapsulated low frequency transformer with EI silicon‑steel core, also known as epoxy potted PCB‑mount EI power transformer.

Different from open‑type chassis‑mount transformers, these potted transformers can be directly soldered to PCB boards, saving cabinet internal space.

We supply two main encapsulated models:
Encapsulated Toroidal Transformer with low magnetic leakage, together with our EI‑core encapsulated low frequency transformer.

They are widely used for industrial control boards, instrument power supplies and household electrical equipment. We support fully‑customized VA power, input‑output voltage, pin layout and dimension for your special project requirements.

FAQ
Q1: What is an encapsulated low frequency transformer?
A: An encapsulated low frequency transformer is an EI‑core power transformer fully sealed with epoxy resin. This epoxy potted PCB‑mount EI power transformer is designed for low‑frequency AC power conversion, with good insulation and shock resistance for harsh working conditions.

Q2: What are the advantages of custom encapsulated transformer?
A: Epoxy potting provides excellent dust‑proof, moisture‑proof and anti‑vibration capability. PCB pin‑mount structure saves equipment space. As a custom encapsulated transformer, power rating, voltage ratio and pin positions can be adjusted according to customer drawings.

Q3: What core types do your encapsulated transformers support?
A: Our encapsulated transformers cover multiple EI core sizes from EI28 up to EI114, also toroidal core options, power range 0.8VA‑1000VA, meet most low‑voltage power‑supply demands.

Q4: Can I get samples for encapsulated low frequency transformer?
A: Yes, sample service is available. Please provide your required VA value, input & output voltage and pin requirements, we will offer quotation and sample solution.

Q5: What applications are encapsulated transformers suitable for?
A: Encapsulated transformers fit industrial control modules, monitoring devices, household appliances, medical instruments and other equipment requiring high‑reliability power conversion.
