Online intelligent Soft Starter FWI-SSL3 series 90KW-630KW
Online soft starters permit soft starting and soft ramp-down of three-phase asynchronous motors Soft stopping function can effectively solve the parking surge problem of inertial systems and that is a traditional starting equipment cannot be achieved.
Rated Current: 320A
Rated voltage: 380/500V
rated insulation voltage： 1200V
Intelligent online soft starter is a new product from our company. This product has a three-in-three-out SCR full-time on-line structure. It does not need an external AC contactor when put in a cabinet. Simplifified primary and secondary wiring costs; Using high-power air-cooled radiators and high-speed axial fans internally to ensure the reliable operation of the soft-start at any time. Our product has perfect motor protection function, when using it, be sure heat dissipation in the cabinet is good. Our product is suitable for the control, soft-start and stepless acceleration in many equipments, like: various AC motors, fans, water pumps, fifire pumps, spray pumps, sewage pumps, deep well pumps, air compressors, brick making machines, crushers, mining machinery and so on.
1. Phase failure protection: When any one of the three phases is disconnected, the protection action time is <1min;
2. Three-phase unbalance protection: When the unbalance of one phase K1 or K2 is> 10%, the protection action time is <10 min;
3. Over-current protection: when the motor stalls, the protector will delay for (± 1) s action;
4. Overvoltage protection: when the power supply voltage UO120%, the protection action time is <1s;
5. Under voltage protection: when the power supply voltage (60% 75%) Ue, the protection voltage action time < 60s;
6. Reset function: manual stop key reset;
7. Over-temperature protection: When the soft-start runs at over-temperature, the soft-start shuts down itself and reports a soft-start overheating fault.
