SCR Digital Power Controllers

Single-Phase

Advanced Digital Technology for High-Temperature Process Control


  • Glassmaking
  • Fiberglass Manufacturing
  • Other Industrial Heating Applications

The Single-Phase 851 Digital SCR Power Controller from Spang Power Electronics offers the latest in Digital Signal Processing (DSP) technology and software. It increases real-time process control information and reduces installation costs.


Through network connectivity, you can improve system performance by cost-effectively linking multiple power controllers for central control through a programmable logic controller (PLC), or an industrial computer.


The Single-Phase 851 Digital SCR Power Controller operates in three different firing modes: 1) Phase-Angle; 2) Zero-Crossover; and 3) Zero-Crossover control into a transformer. The multi-firing mode capability allows for use of a single control amplifier and for common spare parts in multi-furnace facilities. This versatile controller is ideal for precise networked control of power in glassmaking, fiberglass manufacturing and other industrial heating applications.


Three-Phase

The Three-Phase 853 Digital SCR Power controller from Spang Power Electronics offers the latest in Digital Signal Processing (DSP) technology and software. The 853 controller is designed for three-phase applications and has the capability to fire into either direct or transformer coupled loads. The embedded DSP allows for a wide range of options built into one standard package. Spang’s configuration tool software provides the versatility of choosing different regulation modes, control strategies and load types. Interfacing the 853 digital signal power controller with a computer allows the controller to be truly customized for any industrial heating application.
