Fan/pump low voltage soft start drive is a new type of intelligent asynchronous motor startup and protection device. It is motor terminal control equipment for concentrate on startup, display, protection and data acquisition..Users using fewer components that can realize more complex control functions. The Chinese and English display interface makes operation more simple. At the same time, the soft start drive current transformer internal integration that dispense with out-proportioning.
1.Unique SCR trigger. Closed-loop control algorithm unique SCR closed-loop control function, specially designed for special standard load and heavy load.User can choose according to the load current limiting starting and voltage ramp starting, realize the absolute smooth without shock effect of starting torque
2.Unique load application. Parameter built-in ten types of load for users choose. It aim at each type of load to provide unique starting control curve, the greatest degree makes the soft start and load matching to achieve the best effect of start and stop.
3.Multiple start-up and shutdown ways. Voltage index curve, voltage linear curve, current exponential curve and voltage linear curve can apply programmable kick starting torque as well as starting current limit in each mode. According to different overload, which can choose corresponding starting curve to achieve the optimum effect of starting.Various types of parking programmable soft parking, free parking, braking brakes and pump.Unique based algorithm makes the motor start or stop more accurate and smooth.
Fan/pump low voltage soft start amplifier is a solid-state device that protects AC electric motors from damage caused by sudden influxes of power by limiting the large initial inrush of current associated with motor startup. They provide a gentle ramp up to full speed and are used only at startup(and stop, if equipped). Ramping up the initial voltage to the motor produces this gradual start. Soft starters are also known as reduced voltage soft starters(RVSS).
Fan/pump low voltage soft start drive are used in applications where:
1.Speed and torque control are require only during startup.
2.Reducing large startup inrush currents associated with a large motor is required.
3.The mechanical system requires a gentle start to relieve torque spikes and tension associated with normal startup(such as conveyors, belt-driven systems, gears, and so on).
4.Pumps are used to eliminate pressure surges caused in piping systems when fluid changes direction rapidly.
