S811+R13N3S

|

The Eaton S811+R13N3S soft starter is an S811+ series soft motor starter that comes with a Size R frame. It can start or stop industrial motors without causing abrupt changes in the motor’s operating speed and torque, and this helps to eliminate component damage in the system. The S811+R13N3S soft motor starter itself is easy to program and control through its DIM or digital interface module which includes an LCD screen and a keypad. It can withstand 15 g of operating shock and 3 g of operating and non-operating vibration from any direction. Additionally, the S811+R13N3S soft motor starter can operate at a maximum temperature of 50 degrees Celsius and a maximum non-condensing relative humidity rating of 95% without derating.

The S811+R13N3S soft starter is an S811+ series non-combination soft starter manufactured by the Eaton Corporation. The power rating of this soft starter is 40 to 80 kilowatts or 40 to 125 Horsepower over a voltage range of 200 to 600 Volts AC, 3-phase. Its control voltage is 24 Volts DC and its output current is 135 Amps. The S811+R13N3S soft starter can be panel or enclosure-mounted and it is intended for use with 3-phase induction motors in applications that require soft starting or soft stopping processes. Its frame size 110 millimeters, it weighs 4.8 kilograms, and its dimensions are 4.38 x 7.92 x 6.64 inches (W x H x D). The Eaton S811+R13N3S soft starter offers the users a variety of starting and stopping options to optimize performance even in the most demanding applications. Its voltage ramp start allows the users to set an initial torque value between 0% and 85%, and then it constantly increases the torque. Its adjustable ramp time can be set anywhere between 0.5 and 180 seconds, and the current limit start mode limits the current available to the motor during its start phase. These 2 start modes also offer kick start and soft stop starting and stopping options. The digital interface module and communication port on the S811+R13N3S soft starter allow the users the flexibility of local and/or remote configuration, metering, and monitoring. Its communication module supports the Modbus, PROFIBUS, DeviceNet, and other communication networks. The overload capacity of this soft starter is 450% for 30 seconds. Edge and level-sensing control are also available in this unit.

The S811+R13N3S is a soft-starter module that is manufactured by Eaton Corporation. The primary intended use of this Soft-starter device is to implement soft-start and soft-stop methods, protecting the connected 3-Phase AC motor from the unwanted effects of mechanical stress due to sudden change of motor’s rotational direction as well as lower energy consumption due to generation of high-levels of Inrush Current.

The S811+R13N3S supports a variety of starting options such as Voltage Ramp Start, Kick Start, and Current Limit start while configurable motor stopping modes are Soft Stop / Pump Stop. Additionally, this Soft-starter device supports a variety of control functions such as Network control, Local Control, Level or Edge Sensing. Three (3) Reset modes are also available to this device such as Manual, Auto and PowerUp reset.

The S811+R13N3S comes with a Digital Interface Module (DIM) that is embedded to the soft-starter’s front panel. It has an LCD display screen with status bar that can indicate Connection, ISD wiring, Config, Hand / Off / Auto (HOF) Control status. It also has Alphanumeric display with Menu, Data, Parameter Edit, and Data Edit. It also has a soft key function indicator. Operator input is provided by the soft keys for menu navigation and pre-defined keys to allow Local Start and Stop.

The S811+R13N3S has a main supply voltage of 200-600 Volts AC and control circuit voltage of 24 Volts DC. It has a motor rating of 75 Kilowatts @ 400 Volts AC, 50 Hertz and 100 Horsepower @ 460 Volts AC, 60 Hertz. It is a Frame R drive with a rated operational current of 135 Amperes (AC-53 [Ie]) and 234 Amperes @ AC-53, In-Delta [Ie].
