based on the operation of our load regulator, the DSH unit can perform mixed firing of initial phase Angle operation and subsequent full wave operation. Phase Angle triggering is commonly used for three-phase inductive loads or resistors with transformers that have very low cold values that increase with temperature. A typical application is the superkanthal heating element, which has a resistance change from cold to hot equal to 1/15. There is also an effective current limit that can be set by the user to ensure the overall safety of the load regulator in the event of overload and high current peaks. .
