Description:
The types of the DS7 series are soft starters for gently starting three-phase current motors for applications with normal operating frequency and a performance range of 4 to 200 A (1.5 kW to 110 kW at 400 V). Starting transients and DC components during startup are effectively suppressed and guarantee even motor starting. The special actuation method (asymmetrical trigger phase control / Eaton patent) for the soft starter function avoids the DC components that would normally occur in two-phase-controlled soft starters. This suppresses the generation of an elliptical rotating field, which would cause uneven motor starting and increase the motor\'s acceleration. the true run behavior of the DS7 is therefore comparable with a three-phase controlled soft starter.All versions allow a significant reduction of the inrush current for lamps and heaters (with an unearthed star point) by setting a short soft start ramp time (at least 1 s). The ramp times and the start voltage can be adjusted with potentiometers, with the available range for times going from 1 to 30 s (start) and 0 to 30 s (stop) and the available range for the start voltage (starting torque) going from 30% to 100% of the mains voltage. DS7-340...L models feature an internal bypass relay that is switched on automatically after the end of the ramp, bypassing the internal thyristors. This function provides radio interference level “B” in continuous operation without additional measures. The devices\' temperature range has been expanded to an extremely low -40 °C during operation in order to guarantee safe and reliable operation even in extreme situations. Typical applications when used as a soft starter: pump drives - pressure surges are prevented thanks to the soft start; the mechanical load on the whole system is reduced and its service life increases. Fan drives- soft starting prevents drive belt slippage, premature wear is suppressed. This reduces operating costs and extends service life. Conveyors—the conveyor belt starts up gently instead of with a jerk. The conveyed goods do not fall over, the mechanical stress on the conveyor is reduced and its lifespan is increased.
