SCR power controllers provide a relatively economical means of power control. SCR power controllers cost less and are more efficient than saturable core reactors and variable transformers. Compared to contactors, SCR power controllers offer a much finer degree of control and do not suffer from the maintenance problems of mechanical devices. Features & benefits of SCR power controllers over other forms of control include:
High reliability
Because the SCR power controller is a solid-state device, there are no inherent wear-out modes. Thus, they provide virtually limitless and trouble free operation.
Infinite resolution
Power, current or voltage can be controlled from zero to 100% with infinite resolution.This capability allows extremely accurate, step less control of the process.
Selectable control parameters
The SCR power controller can provide useful features such as current and voltage limiting. The ability to control the desired parameter as a function of a command signal & to incorporate limiting features is not normally available with other types of control.
Minimum maintenance
Because they are solid state there are no moving parts to wear out or replace. Therefore, the routine replacement required in some forms of control is eliminated.
