FAQ

What is the difference between phase-angle firing (VAR) and burst-firing (TAKT) modes on the Thyro-A?

Phase-angle firing (VAR) controls power by adjusting the firing angle of the thyristors within each AC half-cycle, providing very smooth and continuous power regulation. Burst-firing (TAKT) switches full cycles on and off, which reduces electrical noise (RFI) but can cause light flicker. TAKT mode is preferred for purely resistive loads where flicker is not a concern.

How do I correctly set the current limit potentiometer for protecting a resistive heating element?

To set the current limit, you should first calculate the maximum nominal current of your heating element. Then, adjust the ‘CURRENT LIMIT’ potentiometer on the front panel to a value slightly above this nominal current to allow for minor fluctuations but prevent overcurrent damage during faults or startup.

Can this Thyro-A 2A 400-60 H RL1 controller be used with transformer-coupled loads?

Yes, it is suitable for transformer-coupled loads. When using it with transformers, the phase-angle firing (VAR) mode with soft-start is recommended to prevent high inrush currents that could damage the transformer or blow the fuses. The ‘TRAFO ADAPTION’ setting may need to be adjusted.
