ABB discontinued soft starter-PST/PSTB (intelligent)

The monitoring function not only monitors software and key soft starter functions, but also monitorsDepending on the input lack of phase and out of frequency range.Integrated bypass contactorABB AF connection is integrated in the larger soft starter (PSTB370 ... PSTB1050).Touch device. It can save you cost (save investment and time in fans and cables), saveSpace (the soft starter is smaller, there is no space-occupying fan and the power consumption is reduced. makeWith the bypass contactor, you can reduce the power loss by at least 90% during normal operation.Consumption).

There is no built-in bypass contactor in PST30 to PST300 soft starters, but it is in the incoming line.Side has reserved bypass contactor connection terminal. When using external bypass contactors, connectThis B1, B2 and B3 terminal enables the soft starter to use the built-in when bypassing.The protection function of.All soft starters can operate normally without bypass contactor.External keyboard (optional)The external keyboard is an optional component, which is installed in the control system.On the cabinet door of cabinet making, without opening the cabinet door, it is convenient toYou can read or set the related parameters of soft starter.Number, external keyboard can also be used to copy multiple software.Parameters between starters.External keyboard PSTEKbus adapterPST soft starter has an interface connected to ABB bus adapter on the front forCommunication of bus adapter. 

Through this interface, the user can control the soft starter.To its status information, upload and download parameters. Between soft starter and bus adapterThe interface is the same. No matter what PST(B) model you use, no matter when you are.Buy, it can always apply any new protocol, because it is set in the fieldbus plug.Righteous. ABB provides most common protocols, such as DeviceNet, Profibus-DP,Modbus-RTU and CANopen protocols. Connect PST(B) soft starter to the field bus system.System, you also need to use the accessories described on page 16-17, and set the PLC.Software, which can be used as a soft starter in www.abb.com/lowvoltage website.Found in the page.Use this function in the stopping process to completely control the torque, especially for the application of pumps.It's good. 

Traditional voltage control will cause sudden torque change, thus causing water hammer.Effect. Torque control minimizes the impact of this problem.Torque limitWhen using the torque control function, the torque can be set and the starting process will not exceed this setting.Fixed value, which will minimize the wear and tear of motor-driven equipment.Analog outputPST(B) soft starter has analog output signal, which can be used as PLC or analog.The input signal of the meter and the output signal can be expressed as motor running current and main electricity.Line voltage, power (horsepower), active power, reactive power, apparent power and power factorNumber, motor temperature or SCR temperature.Analog signal output typeIt can be a standard signal of 0 ... 10V, 0 ... 20mA and 4 ... 20mA. Analog outputThe terminal is shared with the input terminal of PTC protection. Therefore, only analog output or PTC protection can be selected.Guard.
