Our partners
SENSORS
Fundamental components for process control, Gefran's sensors measure main variables such as temperature, pressure, position and force. The main element of the sensors is produced in cleanrooms, in environments protected from any kind of pollutant and equipped with highly technological work and control instruments.
COMPONENTS
Three product lines are dedicated to indicating and controlling process variables: static groups, regulators and electronic indicators. A range of constantly evolving devices capable of providing innovative solutions and responding to the needs of process optimisation and intelligent management of energy consumption. These devices complete the range of support services offered and faster delivery times, the key factors that make Gefran a competitive and reliable partner.
AUTOMATION PLATFORMS
Gefran designs and manufactures automation control systems offering machine constructors a wide range of specific components (Unit Control Panels, Operator Interfaces, input/output systems, as well as programmable logic controllers and industrial PLC). This dedicated division also designs and develops solutions that adapt to customer projects, offering unique and exclusive "turnkey" solutions.
MOTION CONTROL
This range of products, designed and manufactured at the Drive and Motion Control Unit of Gefran in Gefrenzano (VA), consists of continuous and alternating current electronic drives and electric motors, including a complete range to fully satisfy the needs of industrial automation. The line also includes a series of inverters for the domestic and industrial photovoltaic industry.
GEFRAN GFW - Single-bi-three phase power controler, from 400A up to 600A
Single-bi-three phase power controler, from 400A up to 600A
Overview
GFW electric power controllers provide complete single-bi-three phase modular solutions from 40 A up to 600 A per phase, suited to manage linear and non linear loads for electric heating in a wide range of industrial applications, equipped with easy to replace on-board fuses and settable analogue outputs to retransmit controlled variables.
Universal commands
The construction flexibility allows you to control GFW controllers with analogue signals in 0-10V voltage, 4-20mA current, with potentiometers, with ON/OFF linear signals or in PWM mode.
Single signals allow you to control biphase and three-phase models even as single independent single-phase.
The control power values can also be directly sent via one of the multiple available Fieldbus, with convenient cascading IN/OUT connections.
Control functions
To adapt to the multiple possible applications, even the Power module firing choice can be set on the product; you can choose between various types of “Zero crossing” with fixed cycle times or optimised for linear loads and high heat inertia systems, or for fast firing modes, like the Half Single Cycle and Phase angle, to better control non linear loads like SWIR infrared lamps, Super Kanthal and Silicon carbide heating elements or single and three-phase transformer primaries directly.
Soft Start, current limits settable for both peak values and RMS values and closed loop Voltage, Current and Power feedback algorithms complete the control.
A universal PID temperature controller can be built into some models to optimise space and costs and manage a temperature and power control loop with a single device.
