Market number (order): Siemens soft starter 3RW3014-2BB04 Details: SIRIUS soft starters -S00 specifications, 6.5A, 1.5KW / 400V, 40 ° C, AC 200-480V, AC / DC 24V, spring terminals SIRIUS 3RW30 soft starters through a variable phase control reduces the motor voltage, and rise from the beginning of selectable voltage ramp mode to the power supply voltage. When starting, these devices limit the torque and current, and prevents direct starting or star - shock generated when the delta starter. Thus, the mechanical load and the power supply voltage drop can be reduced reliably. Soft-start reduces the stress connected devices, reducing wear and tear, and therefore no longer trouble-free production. The optional start value means that the soft starter can be individually adjusted to the needs of the application in question, and not the star - delta starter in two stages with a fixed limit voltage ratio starts. SIRIUS 3RW30 soft starter at small space requirements for having outstanding features. Integrated bypass contacts mean that after the motor starter, in the transaction without regard to the power semiconductors (SCR) power consumption. Thus reducing heat loss, making the design more compact, and no external bypass circuit. Offers a variety of models of SIRIUS 3RW30 soft starters:? The standard model for fixed-speed three-phase motor, standard S00, S0, S2 and S3, with integrated bypass contact system models for fixed-speed 22.5 mm housing three? phase motor, no bypass starter rated power of 55 kW (400 V), can be used for standard applications in three-phase grid. Which soft starter with a small size, low power consumption and ease of debugging. Contact space functional compact SIRIUS 3RW30 soft starter is only required to compare ratings wye-delta starters third of the space required. This not only saves space in control cabinets and standard mounting rails, but also completely eliminates the wye-delta starter wiring work required. This is particularly evident for high motor ratings, these high ratings rarely used as a high-tech solution. At the same time, connect the starter motor cable and the required reduced from six to three. Compact dimensions, short start-up time, simple wiring and fast commissioning make soft starter has a significant cost advantage. These soft starter bypass contacts at work by an integrated solid-state arc system protection. Thereby preventing damage to the bypass contact when a fault, such as a coil spring operating mechanism or the main operation of the control voltage transient failure, mechanical shock or the defective part associated with life. The new device series with "polarity balancing" control method for the protection of two-phase controlled soft starter in DC components. For two-phase controlled soft starters, two control phases overlap current flows from uncontrolled phase. This also leads to physical cause motor soft starters in three-phase current asymmetric distribution. Although this is not affected, but in most applications still can not be ignored. Control not only leads to an asymmetric power semiconductors, when the starting voltage is less than 50% of the motor starting voltage value, the DC component also led to the previously mentioned serious noise. The control method used for these soft starters eliminates the DC component of the soft starter phase and prevents the braking torque that may arise. This method creates speed, torque and current rise on the same motor soft starters, enabling ease the two-phase motor starter. Meanwhile, the start-up operation of the three-phase control sound quality close to the soft starter. Can be achieved by the motor during the soft-start different polarity half-wave current ongoing dynamic coordination and balance. Hence the name "polarity balancing." ? Voltage ramp soft start; starting voltage adjustment range Us is 40-100%, ramp time tR of 0s ~ 20s. ? Integrated bypass contact system to minimize power loss? Using two potentiometers set? Simple installation and commissioning? Supply voltage 50/60 Hz, 200 ~ 480 V? Two control voltage Model 24 V AC / DC and 110 -?? 230 V AC / DC wide temperature range, from -25 ~ +60 ℃ built-in auxiliary contacts ensure user-friendly controls, and can be further processed in the system. 3RW30 soft starter can be used for three-phase induction motor soft starters. As the two-phase control, throughout the start-up time, the current in each phase is always kept at a minimum. Due to continuous voltage impact, the star - delta starter under conditions of inevitable phenomena, such as current and torque peaks, in this case does not occur. Applications? Pump? Pump? Pump? Press? Conveyors? Roller conveyor? Screw conveyor Auswahlhilfe für Sanftstarter 3RW + Randbedingungen More information 3RW solid-state motor controller configuration is designed for easy start condition. Under abnormal conditions or increasing the switching frequency of the case, it may be necessary to choose a larger device. If the start time is longer, if necessary, must be selected for the start load of heavy overload relay. Recommend using PTC sensor is not allowed in the motor feeder using a capacitive element (eg, you can not use reactive power compensation equipment) between SIRIUS 3RW soft starter and the motor. In addition, both the static system for reactive power compensation, or dynamic PFC (power factor correction), at the start-up and ramp-down of the soft starter can not be operated in parallel. This is to prevent compensation equipment and / or soft starter failure is very important. All elements of the main circuit (for example fuses, switching devices and overload relays) should be loaded in accordance with the case of a short circuit at the start of the corresponding directly for selection. Fuses, switching devices and overload relays must be ordered separately. Please observe the technical data specified in the maximum switching frequency. Note: When you turn on the induction motor, on all types of starters (direct starter, star - delta starters, soft starters) usually produces a voltage drop. Feeder transformer size must be able to achieve this effect: When you start the motor, the voltage drop that occurs not exceed the permitted tolerance range. If the edge of the feeding transformer is dimensioned smaller, it is preferable from a separate circuit (not dependent on the mains voltage) fed to the control voltage, in order to prevent possible soft starter cut case.
