GFW400-600

Product description:

GFW400-600A Overview
GFW electric power controllers provide complete single-bi-three phase modular solutions from 400
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.
