TE Series Digital Solid State Soft Starters 18 – 1250A

1.1 General Description

The TE Series is a digitally programmable solid-state reduced voltage
soft starter. Its six SCR design features a voltage/current ramp with an
anti-oscillation circuit for smooth load acceleration. The SCRs are sized
to withstand starting currents of 500% for 60 seconds. The TE Series
features smooth, step-less ramp control, which reduces motor inrush
current and excessive wear on the mechanical drive train components.
The TE Series includes a programmable keypad for setting operating
parameters for the ideal starting cycle and protection features, plus easy
to understand diagnostic LEDs. Starting torque, ramp time, current limit,
dual ramp, and Decel control are standard features on the TE Series. By
simply adjusting the unit's starting torque, ramp time and current limit
functions, the starting electrical characteristics of the motor can be
matched to the mechanical characteristics of the drive train for controlled
acceleration of the load. The TE Series includes solid-state electronic
overload protection in addition to numerous other protective features. It
requires 120VAC (220VAC optional) control power and uses dry contact
inputs for Start / Stop control. Programmable auxiliary contacts and
provisions for interlocking are also included.
1.1.1 Control Features
Programmable Ramp Types:
Voltage Ramp (VR) or closed loop Current Ramp (CR)
Starting Torque: 0 - 100% of line voltage (VR)
or 0 - 600% of motor FLA (CR)
Ramp Time: 1 to 120 seconds
Current Limit: 200 - 600% (VR or CR)
4 Options:
Ramps 1 & 2 = VR,
Ramp 1 = VR, Ramp 2 = CR,
Ramps 1 & 2 = CR;
Ramp 1 = CR, Ramp 2 = VR
