EI24 0.5VA 12v 220v Sealed Low Frequency Printed Circuit Board Transformer
EI24 0.5VA 12v 220v Sealed Low Frequency Printed Circuit Board Transformer
1.Product Description
The Single Phase EI24 0.5VA Transformer (12V/220V) is a compact, low-frequency power transformer designed for printed circuit board (PCB) mounting, featuring a sealed construction for enhanced durability and moisture resistance. With a primary voltage of 220V and a secondary output of 12V at 0.5VA capacity, this EI24-sized transformer is ideal for low-power control circuits, signal isolation, and small electronic devices. Its high-quality silicon steel core ensures efficient energy transfer with minimal losses, while the compact and sealed design makes it suitable for applications requiring reliable, long-term performance in constrained spaces.
Five Key Features:
1. Compact PCB installation design
2. Sealed moisture-proof protection
3. Low loss and high efficiency
4. Safety isolation transformer
5. Stable low-frequency performance
