The 150-F135NBDB soft starter is product of Allen-Bradley for use in efficient control of motor through solid-state components and microprocessor technology. This product belongs to the Smart Motor Controllers (SMC) products.

When selecting an appropriate motor for this soft starter, the motor Full Load Current (FLA) must be within the current range of the soft starter. Ideally, the soft starter should be slightly higher or 30% higher than the motor’s FLA. Consideration should be applied for motors with high starting current or motors with Ten times higher than the motor FLA.

The 150-F135NBDB does not come with a terminal lug. A terminal lug is ideal for use when terminating wire to this device to ensure adequate torque to avoid vibration, sparks and heat among wire connections. Terminal lug kits for line and delta connections are available as an accessory.

This device is especially made compatible for pump control applications. This product aids in reducing fluid surges during start-up and stopping of pumping system that uses centrifugal pumps. Adjustable starting time is provided with range of 0 to 30 seconds while stopping time is adjustable from 0 to 120 Seconds.

The available starting and stopping modes for the 150-F135NBDB are Soft Start, Current Limit, Dual Ramp, Full Voltage, Linear Speed Acceleration, Preset Slow Speed and Soft Stop. Optional features may be added such as Braking control with Three (3) available methods of braking such as SMB Smart Motor Braking, Accu-Stop and Slow Speed with Braking. Braking control through is not designed to be used as emergency stop.

The 150-F135NBDB Controller is a member of the Bulletin 150 product line of solid-state controllers, and it has been designed and manufactured by Allen Bradley. It is a 3-pole, solid-state smart motor controller, also known as a soft starter, with a current rating of 135 Amps and a Horsepower rating of 100 Horsepower when connected to a 460 Volts AC power source. This electronic device does not need to use any mechanical parts to feed an electric motor with the necessary power to start up and reach its nominal speed. The Allen-Bradley 150-F135NBDB Smart Motor Controller is an ideal candidate for replacing electromechanical starting systems in older machines that are still in operation in many different industries. The users have the opportunity for upgrading their motion control systems, specifically their starting mechanisms, by using the latest technology in solid-state switching like the 150-F135NBDB Controller to stay up to date and keep their machines running for a long time. Soft starters such as the Allen-Bradley 150-F135NBDB Smart Motor Controller have a smaller footprint than traditional electromechanical starting systems, and this allows them to offer the same functions as a contactor and an overload relay while saving panel board space. Having less moving parts in a machine is better in every industry because this allows for easier troubleshooting and therefore less downtime due to unexpected failures. Electronic components like the 150-F135NBDB controller do not need any major maintenance and they help to simplify inventories by eliminating several spare parts and combining others into one simple device. With an easy to operate keypad and a two-line, sixteen-character backlit LCD screen, the Allen-Bradley 150-F135NBDB Smart Motor Controller enables the users to control the motor’s acceleration/deceleration ramps, the initial torque levels, and the initial current limits.
