ELECTRIC HEATERS POWER CONTROLLER 40A…300A SINGLE/TWO/THREE LEGS MODEL
Main features
The GFW electric power controller series was designed to meet the requirements of the industrial electric heating applications with linear and non-linear resistive loads including Silicon carbide (SiC), Silicon-Molybdenum (MoSi2), Graphite, SWIR lamps and transformers, with voltage ranging between 90 Vac to 690 Vac.
Heaters firing mode is fully configurable with:
- ZC: Zero crossing with constant cycle time for conventional linear loads
- BF: Burst-Firing, fast Zero crossing with minimum optimized cycle time for systems with low heat inertia
- HSC: Half-Single-Cycle, which corresponds to a Burst Firing managing also single semi-waves. Therefore, it is ideal for short wave IR lamps: it reduces flickering and limits the generation of EMC disturbance in the power line.
- PA: Phase angle control, ideal to fully remove flickering on short-wave IR lamps, accurately check power checks, correctly manage Silicon Carbide (SiC) and Silicon Molybdenum (MoSi2) non-linear resistors, and transformers’ primary
