COMPONENTELE PENTRU AUTOMATIZARE
Gama de produse pentru afisarea si reglarea variabilelor de proces includ controlere cu microprocesoare electronice, indicatori si relee de voltaj. Upgrade-ul produselor si investitiile in procesele de productie permit oferirea unor servicii impecabile intr-un timp tot mai scurt. 

INTEGRAREA SISTEMULUI
Concepem si dezvoltam solutii la cheie si furnizam producatorilor de utilaje o gama larga de componente specifice, precum unitati de control central, interfete de operare, sisteme de intrare/iesire, controlere logice programabile si computere industriale. 

SENZORI
Senzorii sunt elementele fundamentale in controlul proceselor industriale. Concepem si producem senzori pentru masurarea variabilelor de tipul temperaturii, presiunii, pozitiei, fortei si umiditatii. Toate elementele primare de tip senzor sunt produse de Gefran in propriile spatii curate, medii ce sunt protejate de toate tipurile de interferente si echipate cu instrumente de operare si control, de inalta tehnologie.

ACTIONARI ELECTRICE
Achizitia SIEI, un producator ITALIAN de top pentru mecanismele de actionare electronica pentru reglarea vitezelor motoarelor, a permis integrarea acestei game de produse in cadrul Grupului.

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.

Diagnostic, preventive manintenance and alarms

Some of the strengths of this range include the multiple diagnostic functions, preventive maintenance and alarms for current, voltage and temperature.

  • Total and partial interrupted load alarm with alarm threshold auto-learning
  • SCR short circuit alarm
  • Short circuit or surge load alarm
  • Broken internal fuse alarm

Voltage

  • Incorrect rotation of the three phases alarm in three-phase systems
  • Unbalanced three-phase line alarm temperature
  • Power module temperature monitoring with automatic off in the event of overheating alarm
