TE2-78-BP

Toshiba’s TE2 low voltage motor starter series is a high-end, digitally programmable, reduced voltage solid state starter. This heavy-duty starter provides stepless soft starting of three-phase AC induction motors, which protects mechanical components from excessive torque stress as well as electrical systems from the effects of high motor inrush currents.

Pump-Flex Application Features

The Pump-Flex Deceleration Control helps protect equipment used in applications, such as centrifugal pumps, conveyors, and material handlers, from damages caused by abrupt stopping conditions. When a stop command is given, the deceleration feature gradually extends the stopping time by decreasing the voltage applied to the motor. The check valve then safely and gently closes and the Pump-Flex circuit automatically turns off. Additional features include:

• Pump-Flex Deceleration Control Eliminates Damaging Effects of “Water Hammer”
• Ideal for Irrigation Pumps when Specific Amount of Water Needs to be Pumped if Power Failure or Fault Trip Occurs During Operation
• Elapsed Time Meter, Run-Cycle Counter, Remaining Lock Out Time, & Fault History for Maximum Monitoring & Control of Pumps or Processes

Pumps, Fans, Blowers & Conveyors

Closed loop torque/current ramping provides a linear increase in output torque during acceleration. It maximizes the available torque using an internal PID feedback loop, ensuring a smooth and linear ramp-up to full speed. It is ideal for low pressure pumps where slight surges at the end of the ramp may pose mechanical problems or on fans and mixers where blade warping can be an issue.

Compressors & Chillers

The TE2 offers voltage ramping with current limiting for applications that need the smoothness of voltage ramping while maintaining the ability to start in limited power environments. For maximum motor power where the available power supply is severely limited, a current limit/current step start can be used.
