- Automatic Application Set Up
QFE Main Features
Automatic Application Set Up
Choose your application from the menu "Fan, Pump, Conveyor, crusher..." and the automatic features select the correct ramp profiles, saving setup costs.
Patented 'Fairford System' of Energy Optimising
In certain load conditions Fairford System of Optimising can reduce energy costs by reducing power required by the application, without loss of performance.
6 Button Keypad, 2 Line 32 Character Display
Saves time programming and fault finding because the messages are displayed in English rather than in code format.
Protection
IP20: QFE 9 to QFE 370. IP00: QFE-O 500 to QFE-O 1800.
Fully Programmable
Inputs: 12V DC – 230V AC, Outputs: AC1 230V 3A
Continuous display
Of motor phase current and control status: Starting, Stopping, Full Volts, Optimising, Current Limitations, Overload and fault indication.
Unit Records History of Last 5 Trips
Allows the user to quickly determine which fault the Soft Starter has identified.
Optional Loads; Static Loads, Resistive (Heaters), Inductive (Transformers)
Allows the unit to be used on a variety of differing applications so one unit is highly versatile and therefore saving money..
Modbus or Remote Keypod Option
Eliminating many control items, can be used on a one to one basis or one keypod can control up to 10 Soft Starters.
In Delta Capability
Could reduce the size of the unit needed for the application.
