Electronic soft starter
3 x 480 VAC, 60 - 555 A, 10 - 90 HP(7.5 - 66 kW) | NSFT line Cognito Quam Electrotechnologies Ltd

The NSFTxx soft starters accelerate and decelerate motor loads smoothly, save energy and reduce system wear and tear. They interface with most (if not all) automation equipment in the market and are a favourite mechanical interface in many applications.

They are fully protected, digitally-controlled and programmable units. They are simple to install and are effectively employed in applications driving:
* Transport systems (conveyors, escalators, roller tables etc.) for low inertia loads,
* Pumps and compressors,
* Inelastic transmissions (gear trains, high-ratio belt systems etc.), and
* Fans and ventilators.

Main features include:
* Generous x4 starting current and cooling circuit design provides for 60-555 A (starting, per phase), 10-90 HP/7.5-66 kW (at 3x400 V) loads.
* User selectable starting current limitation to control the acceleration torque.
* Complete and comprehensive electronic protection: overcurrent, undercurrent, over/under-voltage, phase sequence and integrity, noise and line disturbances and internal temperature.
* Isolated, versatile two input user/control interface.
* Selection of fault handling, trigger/control type, profile, deceleration, starting value and duration, operation timer by DIP switch.
* Galvanically isolated bit outputs.
* Load current signal analog output.
* Overcurrent limit can also be set externally via the analog input.
* Small 24 VDC power supply to power a local sensor or other automation device.
* Installation-friendly, robust, space-saving "bookcase" style enclosure.
* Separate 1x230 VAC control circuit supply.

The line is also available in ready-to-install, completely assembled systems.
