EI35 220V to 10.5V 150mA 50Hz Low Frequency Step Down Isolation Power Transformer
This EI35 low-frequency step-down isolation power transformer converts 220V 50Hz mains AC input into stable 10.5V AC output at 150mA. Built with classic EI laminated silicon-steel core and fully separated primary-secondary windings, it delivers complete galvanic isolation for enhanced circuit safety.
Compact open-frame PCB pin-mount structure saves cabinet space, perfectly suited for control board power supply of small household appliances, smart devices, and low-power industrial control modules. After paired with rectifier circuits, it provides reliable low-voltage power for relays, microcontroller boards and auxiliary electronics. RoHS compliant, suitable for mass OEM & ODM projects.
Key Advantages
Complete Galvanic Isolation: Fully-isolated primary and secondary windings block mains surge and common-mode noise, protecting downstream circuits and improving equipment safety performance.
Stable Output & Low Loss: High-quality laminated silicon-steel EI35 core minimizes eddy-current and hysteresis loss; maintains steady 10.5V@150mA output under rated working conditions with low temperature rise during continuous operation.
Compact PCB Pin-in Design: Standard EI35 footprint with through-hole pins for direct PCB soldering, easy assembly for mass production, ideal for space-constrained electronics enclosures.
100% Pure Copper Winding: Oxygen-free copper coil guarantees low internal resistance, stable power transmission and long service life, avoiding overheating risks caused by aluminum windings.
Strict Quality Assurance: Every transformer undergoes 100-percent factory testing including hipot withstand-voltage, no-load and full-load inspection. RoHS compliant to meet global market access requirements.
Flexible Customization Available: We support custom input/output voltage, output current, winding parameters and insulation class for your specific project requirements.
