Nietz - Model SSM Series -Medium Voltage Soft Starter
High performance of SSM is ensured by 32bit ARM core micro-controlling technology, high speed optical cable together with dynamic and static protecting measures. Motor torque increased to rate torque as voltage and current rises which is controlled by 32bit ARM core controller through phase shift triggering technology . SSM medium voltage soft starter decreases current flush thus impact to motor and electric network are reduced. Life time of machineries is prolonged and breakdown is lessened for reduced impact.
- Maintenance-free: not like other devices which require maintenance for liquid or wear parts, a contactless switch and can operate several years without any maintenance.
- Ease installation and operation: SSM is an integrated controlling and protective unit, the only job for customer is to connect it with power supply cable and motor before operation. Low voltage is permitted to apply to the device for electrical test.
- Backup function: A vacuum contactor is installed in SSM cabinet and customer may start the motor by switching on the vacuum contactor to prevent system breaks down in case SSM gets in fault.
- Thyristor SSM is designed with a magnetic locking device to prevent breaking in after SSM is energized.
- The fiber-optic transmission system insured isolation between high voltage thyristor trigger detecting circuit and low voltage control circuit.
- Command from the control center is execute by the 32 bits ARM core which ensures reliable and steady real time control with direct displaying.
- Dual-language Chinese/English Liquid crystal displaying screen /touch screen for data displaying and humanized interface for operation.
- SSM integrated a RS485 port which can communicate with host computer or collective control center.
- Comprehensive motor protections provided by micro-processer.
- Compact design with unique structure of heatsink, insulation of high voltage elements and low voltage elements which ensures a safe operation.
- Turbo blowers / Sinter fans
- Centrifugal blowers / Blast furnace blowers
- Wind-tunnel drive / Gas compressors
- Turbo compressors / Screw compressors
- Pipeline compressors / Cryogenic compressors
- Centrifugal compressors / Reciprocating compressors
- High pressure injection pumps / SAG mills / Ball mill systems
SSM is to start and stop as well as protect squirrel cage asynchronous motors and synchronous motors from 3000v to 10000v used in Metals Industries, Petroleum industry, Chemical industry, Irrigation, Electric Utility, light industry, Pharmacy, Mining, municipals and many other industries.
SSM works nicely with all kinds of machineries like water pump, fan, compressor, crasher, blender and belt conveyer, and is an ideal control and protective device for high voltage motor.
