Control Concepts Inc. founded in 1980, is the market leader in the design and manufacture of stock and custom SCR power controllers for industrial heating applications.
Their single-phase and three-phase, zero-cross and phase-angle power controllers have voltage ratings ranging from 120 to 575 volts and current ratings ranging from 10 to 2000 amps.
We recognize power control applications have demanding environments and require extremely high product reliability. Product reliability translates to less down time and increased profits. When you use a Control Concepts power control system, reliability is designed in and superior customer value is created by the following:
MicroFUSION is an ultra-compact high performance microprocessor-based line of power controllers, available in single or three phase models.
Resistive or transformer-connected loads can be controlled in either Phase Angle, Zero Cross, or Zero Cross Transformer (ZCT) Mode. Output is controlled linearly with respect to command signal and can be set to the average or RMS value of the voltage and current, as well as true instantaneous power or external feedback.
The Compact Fusion Series Power Controller is a modular digital controller capable of single phase and 3 phase operation.
- Integrated Class-T, Branch-rated fusing to prevent dead shorts and reduce fuse-blowing.
- UL 508A branch fusing requirements
- Remote Control Display
- Profinet (Ethernet)
- Modbus TCP (Ethernet)
All Control Concepts' FUSION and Compact FUSION digital power controllers have been tested up to 100 kA with internal protection of the current limit and over current trip defeated. This rating only pertains when the volume of the enclosure is a minimum of 150 percent of the controller volume, the enclosure has two latches on the cover and the controller is protected with Class T or High Speed J fast acting fuses.
Utilizing Phase Angle control has disadvantages - increased harmonics and decreased power factor. However, it is still the usual choice for system designers with isolation transformers in order to prevent transformer saturation.
Control Concepts has recently introduced a new solution: Zero Cross Transformer (ZCT) Mode. Their goal was to develop a cost-effective way to eliminate harmonics/power factor issues without compromising performance, quality, or reliability. ZCT Mode is already in use on the field and has produced excellent results.
