What are the key differences between the Autonics SPC1 Series and SPC3 Series?
The key differences between the Autonics SPC1 Series and SPC3 Series Power Controllers mainly lie in their control capabilities, performance range, and application flexibility. The Autonics SPC1 Series is a single-phase power controller designed for simple and compact heating applications. It supports both phase control and zero-cross control, allowing users to choose between smooth or stepwise power delivery. The SPC1 Series comes in various current ratings, such as SPC1-35 (35A) and SPC1-60 (60A), suitable for controlling resistive or infrared heating loads. It’s ideal for basic heating processes like ovens, dryers, and sealing machines, where stable and cost-effective power control is needed.
In contrast, the Autonics SPC3 Series is a three-phase power controller designed for more complex and high-power industrial systems. It can manage larger loads and provides independent phase control for precise output management. The SPC3 Series offers enhanced protection functions such as short-circuit, overcurrent, and overheat protection, ensuring higher reliability in demanding environments. It also supports analog input signals (4–20mA or 0–5V), making it easier to integrate with temperature controllers or PLCs. The SPC3 Series is suitable for advanced applications like injection molding, semiconductor heating, and large-scale furnaces, where precise power regulation across multiple phases is critical.
In short, the Autonics SPC1 Series is best for single-phase, small to medium heating systems, while the Autonics SPC3 Series handles three-phase, high-load industrial applications. The SPC3 offers more control accuracy, protection features, and input flexibility, whereas the SPC1 focuses on simple, reliable, and efficient power control for everyday automation needs.
