Step-down Transformers
A. Overview A transformer that converts high voltage into low voltage. B. Features The step-down transformers has the characteristics of large randomness of products, single structure, high magnetic performance utilization, relatively low temperature rise, relatively high working efficiency, and good cost performance. C. Design Considerations 1. High work efficiency 2. Low working loss 3. Thermal protection 4. Low vibration and noise 5. International Power Transformer Safety Standard 6. Power 10VA to 10KVA D. Temperature resistance and product temperature rise Typically we design that over ambient of 25°C, the temperature rise is as follows: 1. Class A: 105°C, Temperature rise below 60°C 2. Class B 130°C, Temperature rise below 75°C 3. Class F 155°C, Temperature rise below 95°C 4. Class H 180°C, Temperature rise below 125°C 5. Or suitable temperature grade and suitable temperature rise E. Compliance Standard IEC61558 F. Design required parameters 1. Input voltage (V) 2. Working frequency (Hz) 3. Output voltage (V) 4. Output current (A) or output power (W) 5. Transformer installation space 6. Transformer installation and connection method 7. Requirements of temperature resistance level, efficiency, power consumption
