Ram Industries Electric 460V Reduced Voltage Starter – 269 HP
Motor starter made by Ram Industries: RI1 FDP265A. AC3: 265A. AC1: 350A. Part Ram IndustriesDBSC3-JR. Serial: ATR-019. Max HP: 208V / 119 HP, 230V / 131 HP, 460V / 269 HP, 575V / 335HP. Max FLA: 325. Max LRA: 2350. DBS. Ram Industries Leesport, PA. Starter overall dimensions: 18 L x 11 W x 13.5 H (inches). The DBS (digital bypass solid state) reduced-voltage starter is a microprocessor controlled motor starting device which utilizes six SCRs (silicon controlled rectifiers) to electronically reduce the applied voltage to an AC induction motor, allowing the motor to start at a reduced current. Because the DBS accelerates the motor in a smooth stepless manner, it reduces drop in the supply voltage as well as mechanical shock on the driven equipment, that is normally experienced with two-step, electromechanical, reduced-voltage starting methods. The DBS can be progRam Industriesmed to provide a gradual build up of torque, from Zero Mfg. Co to almost full motor locked rotor torque, or to limit starting currents to a constant value, which prevents an excessive voltage drop during motor starting.
