Custom Encapsulated Low Frequency Transformer | Epoxy Potted PCB‑Mount EI Power Transformer

Description

Custom Encapsulated Low Frequency Transformer | Epoxy Potted PCB‑Mount EI Power Transformer

Our custom encapsulated low frequency transformer, also known as epoxy potted EI transformer, adopts epoxy potting process for full encapsulation. As one of reliable encapsulated transformers, it is widely chosen for harsh‑condition electronic equipment.

This PCB‑mount encapsulated transformer features silicon‑steel EI core, stable low‑frequency power conversion, good insulation, dust resistance and excellent vibration resistance. Compared with ordinary chassis mount transformer, this pcb pin mounting power transformer saves cabinet space and supports direct soldering onto PCB boards.

We can customize VA power, input‑output voltage ratio, pin assignment and winding parameters for your projects. Our encapsulated EI low‑frequency transformer is widely applied in industrial control boards, household appliances, instrument power supply and other low‑voltage power conversion scenarios.

We supply a full range of encapsulated transformers to meet diverse power‑supply demands. Custom service is supported for special dimension and insulation requirements. Send us your specifications for quotation and samples.
