DT661H27S
Drive Isolation Transformers - PN
Drive Isolation Transformers facilitate SCR (Silicon Control Rectifier) variable speed motor drive systems by providing magnetic isolation between the incoming line and the motor drive. These transformers also adjust the voltage to align with the SCR Drive requirements. The standard configurations include a delta primary and a wye secondary, which are compatible with the typical power sources found in three-phase rectifier circuits. This model, designated as PN DT661H27S, supports various kVA ratings ranging from 7.5 to 440 kVA. It operates on multiple input voltage ranges of 460-575 Vac and features an output voltage range of 133-460 Vac. The transformers are designed for three-phase systems and can accommodate varying drive horsepower from 5 to 400 HP. With aluminum windings, the transformers are rated for a temperature rise of +150°C, ensuring durability in demanding applications.
