Selection Guide
Use the GFX4 model code to select the right variant for your application:
- GFX4 — Series identifier (modular SCR power controller)
- IR — Firing mode: IR = Phase-angle; ZC = Zero-crossing
- 80 — Rated current: 25 / 40 / 60 / 80 / 100 / 125 / 160 A available
- 0 — Supply voltage option (0 = standard 24–600 V AC)
- 2 — Control input: 1 = 0–10 V; 2 = 4–20 mA; 3 = potentiometer
- 0 — Communication: 0 = none; 1 = RS485 Modbus
- 0 — Additional options (0 = standard)

Replacement & Compatibility FAQ
Q: Can I replace GFX4-IR-80-0-2-0-0 with a GFX4-IR-80-0-1-0-0?
A: Yes, if your control signal is 0–10 V DC. The -0-1- variant accepts voltage input instead of 4–20 mA. Wiring change required at the control input terminals only.
Q: Is the GFX4-IR-80-0-2-0-0 compatible with three-phase loads?
A: No — this is a single-phase unit. For three-phase loads, use three units in a star or delta configuration, or select the GEFRAN GFX4 three-phase model.
Q: What is the difference between IR and ZC firing modes?
A: IR (phase-angle) provides smooth, continuous power variation — ideal for resistive heaters. ZC (zero-crossing) switches full cycles on/off — better for transformer loads to avoid inrush current.
Q: Can I use a 100A model as a direct replacement?
A: Yes, a higher-rated model (e.g., GFX4-IR-100-0-2-0-0) can replace an 80A unit safely, provided the heatsink and enclosure accommodate the larger form factor.
Q: Do you provide a datasheet or wiring diagram?
A: Yes — contact support@konmask.com and we will send the official GEFRAN GFX4 technical manual.
