Description
50/60Hz Low Frequency Laminated Core Auto & Isolation Transformer
Product Overview
Our 50/60hz low frequency transformer uses EI/UI grain-oriented silicon steel laminated core with full oxygen-free copper winding, including isolation transformer and auto transformer types for global mains AC power conversion. All our low frequency power transformers are manufactured in accordance with IEC power component safety standards.
This series transmits AC voltage and power, realizes circuit impedance matching, and provides effective DC isolation. Different from high-frequency ferrite transformers, low-frequency laminated core transformers adopt grain-oriented silicon steel sheets to maintain stable performance under 50/60Hz mains frequency.
We fully customize input/output voltage, power rating, outgoing wire specification, and offer fully epoxy encapsulated waterproof sealed versions.
Core Advantages Of Low Frequency Transformer
- Compact laminated EI/UI core structure, stable mechanical structure
- Low magnetic leakage, low hum noise during continuous operation
- High conversion efficiency, low copper loss and core loss
- Low temperature rise under full rated load, stable output voltage
- CE, RoHS, ISO9001, CQC full certification for global industrial & medical equipment
- Optional metal mounting brackets, fully epoxy potting for dustproof, waterproof and shock resistance
