Gefran – GFX4‑IR‑80‑R‑2‑0‑0 – GFX4‑IR Modular Power Controller

Main Features

• Manufacturer: Gefran – GFX4‑IR series  

• Model/MPN: GFX4‑IR‑80‑R‑2‑0‑0 (also referenced as GFX4IR80R200)  

• Device Type: Modular power controller combining solid-state relays, SCR drive, current transformers, and optional fuse holders – designed for controlling heating elements such as SWIR lamps  

• Power & Output: Four independent PID control loops with embedded SSRs; each channel capable of switching up to 80 A rms – suited for up to 80 kW combined load  

• Control Modes: Multiple configurable firing strategies: zero-crossing, burst firing, single-cycle, and phase-angle control—optimized for SWIR or inductive heating loads  

• Input & I/O: Standard unit includes 4 universal main inputs; second variant offers 4 auxiliary analog inputs plus 2 digital inputs and 2 digital or relay outputs (model suffix “P”)  

• Alarm & Diagnostics: Monitors current, voltage, temperature, load imbalance, SCR faults, phase loss/sequence errors; includes load “teach-in” alarm functionality  

• Mounting & Connectivity: DIN-rail or panel mount; compact modular design with plug-in I/O blocks and fuse slots

• Standards & Safety: 4 kV isolation rating, suitable for 400–480 VAC systems; widespread use in industrial thermal process control
