Motor soft starter SAK31

semiconductorelectronicAC

The FEAS-softstarter is an electronic starter for AC-motors of the squirrel cage winding with slip-ring rotor constructional type. The function of a soft starter is to allow AC-motors to accelerate smoothly up to nominal speed, whereby the ohmic resistance has been replaced by a low-loss, bidirectional power control semiconductor. The motor is connected up so that the electronic resistor is in series with one of the three supply wires. No star delta run-up necessary soft and shock-free run-up Reducing the starting current little run-up noise Adjustable run-up time Adjustable starting torque Operating status shown by LED Integrated relay with potential-free change-over contacts small dimensions Suitable for the tropics Safety acc. to VDE, EN, UL, CSA Input voltage (VDC): - 3 x 400 VAC / 3 x 440 VAC (without N) Output voltage (VDC): - 3 x 400 VAC Operating temperature range: - -20°C / +70°C Dimensions (WxHxD): - 55.0 x 75.0 x 110.0 mm Weight: - 0.65 kg
