SCR power controller, power regulator
Overview
SCR power regulators are widely used in different power regulation equipment in the industry, such as kilns, thermal treatment furnaces, electric heating furnaces, electroplating equipment, launching machines, extruders, high cycle machines, etc. The power regulators of the company are applicable to various kinds of equipment in different control modes to meet the requirements of clients.
Features
·Sealed IC circuit boards of SCR power modules are used
·Full electronic safety devices (quicker than high rate fuses), in the time of passing current, it automatically cuts off the trigger devices to protect the controlled silicon.
·Exceptional interference resistance, capable of being used for transformer load, high frequency device earlier stage voltage regulators
·With current feedback applicable to negative resistance load such as silicon molybdenum rods, platinum heaters
·Capable of performing different control changes (e.g. fixing current and voltage)
·Easy for installation, not easy to be impacted, with high control accuracy
