- Applications
- Features
| SCR Controlled Heating or Furnaces, 3-ph Rectifier Input DC Power Supplies, 3-ph Switched Mode Power Supplies and General Purpose Applications |
| Designed for the requirements of both adjustable frequency and DC motor drive power isolation, 6-pulse drive applications |
| Meets 4% minimum reactance for 150 deg C temperature rise designs |
| Conforms to IEEE-597 class B overload, which requires 150% of load for one minute per hour |
| Designed for the thermal and mechanical stress of highly cyclic process control applications |
| Drive isolation transformers provide reactive control of current harmonics for both AC and DC motor drives, either static bridge or SCR switch input type |
| Aluminum windings |
| (2) +/-1 at 5% taps |
