The smart motorstarter function is a softstart, reversal and protection of 3-phase asynchronous motors. Overcurrent is detected when the set current is exceeded longer than 2 sec. Direction reversal takes place via relay switching. The relays are de-energised at this. This ensures a long service life.
Features
• According to IEC/EN 60 947-4-2
• To reverse 3 phase motors from 90 W to 750 W resp. 550 W to 4 kW
at AC 400 V
• 2-phase softstart
• Max. 4 potentiometer für setting of starting torque, deceleration torque,
softstart /-stop, overcurrent limit or rated motor current
• 4 LEDs for status indication
• Reversing with relays without current, softstart, softstop with thyristor
• Galvanic separated 24V-inputs for clockwise- and anticlockwise
• Reset button on front
• Connection facility for external reset button
• Relay indicator output for operation
• Indicator output at customers specification (on request)
• Galvanic separation between control circuit and power circuit
• Width: 22.5 mm
