1 EDIU VOLTAGE DRIVE STARTER TYPE V-S-L1 UP TO 20 W UP TO 12 KV UP TO 520/2500 A

2 OCOTECH PRESENTS THE VARIABLE FREQUENCY DRIVE STARTER TYPE V-S & The V- is based on multi level voltage source inverter technology for continuous operation and designed as V-S for short time operation. Drive starter applications: Starting of standard asynchronous and synchronous motors. Retrofit to any existing inductionand wound rotor motor. The highly sophisticated guarantees a very smooth continuous speed control and step-less acceleration without any mechanical shock to the motor and the load (if used as S drive starter until full speed and the bypass is closed). CUSTOER ADVANTAGES Up to 520 A output and 2500 A by-pass current at 2,3 kv Starting current rated motor current up to rated motor torque Starting current is a fraction of motor current at reduced load No need to oversize feeding transformers or generators No starting related voltage drop in the power supply Synchronized by-pass control Zero active power losses after by-pass closed Improves efficiency saves operation cost Perfect sinusoidal waves No harmonic filter required inimum common mode voltage to motor winding Negligible torque ripple, noise and heat caused by harmonics in. du/dt and di/dt very low EI Long motor cables possible PW based U/f also called VVVF control PW based vector control incl. field orientation control Open and closed loop control Increases lifetime of drives and machines Highest availability and operation stability Cost saving compact modular design with many options All equipment available in the drive starter, ready for operation: Input contactor Output contactor By-pass contactor ulti level phase shift input transformer Starting power electronics HI + central controller + PLC for starting control Totally digital controlled with self-test diagnostic function any acceleration/starting ramps possible Soft start/stop function with lowest mechanical stress Load dependent calculated starting voltage and current Inductive full load test before delivery
