Secondary AC Current Requirements
Since transformers may be used in many possible configurations, the current ratings shown above are AC-RMS secondary winding currents. When selecting the “Secondary Amp” rating, the conversion chart shown below may be helpful.
| Rectifier Type | Filter Type | Approximate Secondary RMS Current |
|---|---|---|
| Full Wave Center Tap | Choke Input | .7 times DC Current |
| Full Wave Center Tap | Capacitor Input | 1.2 times DC Current |
| Full Wave Bridge | Choke Input | Equal to DC Current |
| Full Wave Bridge | Capacitor Input | 1.8 times DC Current |
