Specification
Ⅰ. Specifications and Selection
1 Q: We need a 220V to 12V step down transformer. What specifications will be needed for production?
A: Please provide the following key parameters, the more detailed the better:
Input Voltage (Primary Voltage): For example, AC 220V. Is there an allowable fluctuation range (e.g. ±10%)?
Output Voltage and Current (Secondary Voltage & Current): For example, AC 12V, what current (A) or power (VA/W) is needed? If there are multiple output groups, please list the voltage current of each group.
Rated Power (Rated Power): The unit is VA (volt-ampere) or W (watt). This is one the most important parameters, determining the transformer's load-carrying capacity.
Frequency (Frequency): 50Hz or 60Hz?
Construction (Construction): Is it toroidal, EI type (frame-type), or R-type? Is there a special installation method (such vertical, horizontal, with a base, with a cover)?
Insulation Grade (Insulation Class): For example, Class A (105°C), Class (120°C), Class B (130°C), which is related to the transformer's heat resistance and lifespan.
2. Q: What is the difference between the power unit VA and W? How should I choose?
A: For purely resistive loads (such light bulbs, heating tubes), VA ≈ W. For inductive or capacitive loads (such as motors, appliances), W (real power) < VA ( power). To ensure safety, please select according to the apparent power (VA) of the load and leave a margin of 20%-30%. For example, 100W motor, it is recommended to choose a transformer of 120VA-150VA.
3. Q: Toroidal transformer or traditional EI transformer, which one should I choose?
A: The main differences are as follows, please choose according your priorities:
Characteristics | Toroidal transformer | EI Transformer |
Efficiency | High (no air gap in magnetic circuit) | Lower |
Leakage Magnetism/ Interference | Very little (magnetic field enclosed) | Larger |
Volume and Weight | Smaller and lighter (for the same power) | Larger and heavier |
Production Process | More complex | Mature and simple, easy to maintain |
Application Scenarios | High-end audio, precision instruments occasions with high EMI requirements | General industrial equipment, conventional power supplies, cost-sensitive applications |
Cost | Higher | Lower, cost-effective |
