The 850 Series Digital SCR Controllers have been in the industrial marketplace since the late 1990’s. With a strong technology focus, Spang continues to development innovative and reliable power control and conversion equipment. The 850 Series technology advantages allow Spang to easily retrofit existing control functionality that may have become outdated either by new process requirements or obsolescence. The 851 & 853 digital power controllers are Spang’s single phase and three phase offering for standard product and custom systems installation, integration, or retrofit.
The 850 Series digital technology allows Spang to provide custom configurations, both hardware and software, to meet specific mounting, cooling, and packaging requirements, ratings above industry standards, process specific control algorithms, and specialty feature sets or control functionalists.
850 Series Products
851 Series – 1PH VAC / Phase Angle & Zero Crossover
The 851 single phase power controller allows for real-time readings of voltage, current, power and fault conditions, as well as for real-time setpoint changes to adjust power levels for process requirements. The controller provides complete user customizing capabilities without rewiring or adding additional components. Spang also offers an expanded feature set for the 851 controller that includes network communications and digital display options.
