Infrared lamps for industrial heating single phase load

Thyristor Unit to control infrared lamps for industrial heating single phase load, Infrared Short Wave loads can be driven with different types of Firing: Single Cycle, Burst Firing and Phase Angle with Current Limit. The inrush current remains high for a longer period if we use Phase Angle plus Current limit, than with Single Cycle. Single Cycle technique is the most used to drive infrared short waveform. During the Off time the IRSW elements become cold (due to their low inertia) and when switched ON again there is a peak of current. This peak of current is a function of the number of Burst Firing Cycles, for this reason the Off time must be as short as possible to reduce this current peak.Phase Angle firing is not used because the supply voltage is normally less than nominal and therefore the elements never reach the working temperature.
