Description
Soft starter
1. SJR3-3000 High-torque Intelligent Soft starter, Power starter, motor soft start, Motor starter, Soft control,
2. CE, ISO9001, SGS, CCC certificates, etc
3. Features:
--- The unique closed-loop torque control of Shanyu (Shanyu patent), was specially designed for standard load and heavy load.
--- The only on-line soft starter, can not take the contactor bypass running on-line, and can also use a contactor to bypass, colleagues will keep full protection
--- In the period of acceleration and deceleration can linear control the supplying motors torque(a significant fluctuations of reduction in pressure )
--- Easy to adjust the slope and the starting torque
--- Advanced integrated protection functions: Overcurrent, overload, less on the load, lack of phase of input-output, overheating
--- Plug-in programmable I / O terminals: 4 logic inputs, 2 logic outputs, 3 relay outputs
--- Analog output, 0-20mA / 4-20mA to switch.
--- Motor preheat function.
--- Built-in protection box PIC directly protect.
--- Configure two sets of motor parameters, easy to adjust the control parameters.
--- Dynamic fault memory.
--- Electrical parameters, load conditions and running time
--- LCD liquid crystal display
--- RS485 communication, MODBUS standars protocol.
--- Field bus communication and Ethernet, Fipio \ DeviceNet and Profibus DP network communications
--- PowerSuite Pocket PC and software
--- High-end products. Applications meet the highest requirements. More advantages will not repeat them.
