Customized EI66 Low Frequency Power Supply Transformers Square Inverter 110V 220V

1.Product Description

EI66 power supply transformers are compact, cost-effective laminated transformers commonly used in low-power electronic applications. The "EI" designation refers to their stacked E-shaped and I-shaped iron core laminations, which reduce eddy current losses, while "66" indicates the core's approximate 66mm width. These transformers typically operate at 50/60Hz frequencies with power ratings ranging from 5VA to 50VA, offering reliable voltage conversion for circuits requiring isolation or step-up/step-down functionality. Their robust construction features enameled copper windings and varnish-impregnated cores for noise reduction. EI66 transformers are widely employed in power adapters, audio equipment, control systems, and small appliances due to their simple design, high efficiency (typically 85%-92%), and easy manufacturability. Proper selection requires consideration of input/output voltage, load current, regulation, and temperature rise specifications.

Here are three key features of Customized EI66 Low Frequency Power Supply Transformers / Square Inverter Power Transformers:

1. High Efficiency & Low Losses

   • Optimized EI-66 laminated silicon steel core minimizes eddy current and hysteresis losses, achieving 85%-93% efficiency even under low-frequency (50Hz/60Hz) operation.

2. Robust Square Wave Compatibility

   • Specially designed to handle non-sinusoidal (square wave) inverter loads without saturation, ensuring stable voltage output under harsh power conditions.

3. Flexible Customization

   • Supports tailored designs for input/output voltages, multi-tap windings, shielded layers (EMI suppression), and potted construction for harsh environments (e.g., industrial/UPS applications).
