GFX4-IR Power controller 4 PID loops for SWIR lamps up to 80kW

GFX4-IR

Overview

GFX4-IR is a four-independent loop controller, designed to manage electrical power.

GFX4 is a compact unit bounding different technological elements like:

  • controller
  • solid state relay
  • current transformers
  • fuses-holders (option)

The final result is a cost-saving in terms of space and cabling.

The GFX4-IR is managed by a microprocessor that independently controls the four control loops and also runs functions specifically designed to manage single-phase and 3-phase loads, with low and high-temperature coefficient, medium and short wave infrared lamps, and transformer primary circuits.

The multiple activation methods are all software-configurable, and include:

  • Zero crossing with constant cycle time for conventional loads
  • Burst firing with variable cycle time for systems with low thermal inertia, medium wave IR lamps
  • Single cycle for short wave IR lamps with reduced flickering (half single cycle)
  • Phase angle control with a current limit for short wave IR lamps, transformer primaries, with an assignment of soft start-up and soft stop down options with limitation of max. RMS current.

GFX4IR runs complete diagnostics of current, voltage, and temperature levels:

Current

  • Total and partial interrupted load alarm
  • "Teach-in" function for self-learning of alarm threshold for interrupted load
  • SCR in short circuit alarm
  • Load in short circuit or in overcurrent alarm
  • Unbalanced 3-phase load alarm

Voltage

  • Phase loss in case of 3-phase configurations
  • Check of correct phase sequence alarm

Temperature

  • Overtemperature alarm

Various feedback functions in the absence of PID control have been developed for complete control of loads in all types of applications:

  • Voltage feedback (V) with current limit
  • Current feedback (I)
  • Power feedback with maximum power limit

Configuration is changed by setting simple parameters with a software tool that guides the user to a correct and safe configuration.

GFX4-IR dialogs with the operator terminals according to the most popular protocols: from the simple and efficient Modbus to (via a second optional Fieldbus communication) the by-now indispensable Profibus DP, CANopen, DeviceNet, Modbus RTU, Ethernet Modbus TCP, Ethernet IP.

The product comes with a standard configuration that is simple and quick to modify, for example, to assign different functions to outputs.
