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:
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.
Robust Square Wave Compatibility
Specially designed to handle non-sinusoidal (square wave) inverter loads without saturation, ensuring stable voltage output under harsh power conditions.
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).
| Feature | Description |
| Core Material | High-grade silicon steel (EI-66 lamination) for low hysteresis & eddy current losses. |
| Frequency Range | Optimized for 50Hz/60Hz low-frequency operation (suitable for inverter applications). |
| Power Rating | Customizable from 10VA to 100VA (typical), depending on design requirements. |
| Input/Output Voltage | Tailored windings for AC/AC or AC/DC conversion (e.g., 110V/220V input, 6V-48V output). |
| Efficiency | 85%-93% (depends on load and design), with low no-load losses. |
| Isolation | Reinforced insulation (up to 4kV withstand voltage) for safety compliance. |
| Thermal Performance | Class B/F insulation, rated for ≤75°C temperature rise under full load. |
| Construction | Vacuum impregnated windings, epoxy-coated for moisture/chemical resistance. |
| Noise Level | Low vibration & audible noise (<40dB) due to tight core lamination. |
| Custom Options | - Multiple secondary taps |
| - Shielded windings (EMI reduction) | |
| - Potted or encapsulated designs. | |
| Compliance | Meets UL/IEC/EN61558 standards (optional certification). |
| Applications | Inverters, UPS systems, industrial controls, renewable energy systems. |
