CUSTOM POWER CONTROL
Engineered For Your Application
When electrical requirements, mechanical constraints, or system architectures fall outside catalog products, Control Concepts engineers build the solution from the ground up.
Overview
Custom solutions, designed together.
2-10x cost reduction compared to standard controllers.
Are you looking for a minimal cost and footprint, custom-branded controller with unique features and system-specific integration?
Control Concepts works directly with OEM engineering teams to develop application-specific power controllers based on thyristor (SCR), IGBT, or FET- power topologies.
We are the extension of your engineering team that specializes in power control.
Problems we solve…
Control Concepts develops custom controllers when process stability, integration requirements, or electrical demands exceed standard product capabilities.
Cost, Footprint, and Complexity from Unnecessary Features
Standard controllers may have unnecessary features that increase cost, enlarge footprint, or require complex configuration.
Electrical Limits Exceeded
Electrical requirements exceed standard product voltage or current limits, demanding custom power stage design.
Specialized Firing Strategies
Heating processes require specialized firing strategies optimized for specific load behaviors and thermal requirements.
Unique Mechanical Integration
Mechanical integration requires unique size and enclosure/mounting configurations to fit within OEM equipment architecture.
Proprietary Control Integration
OEM equipment require proprietary control system integration for direct communication with machine control platforms.
Multi-Zone Coordination
Multi-zone heating systems require coordinated power control across multiple zones within a single architecture.
High-Value Process Stability
The application involves high-value manufacturing processes where power stability directly affects yield and quality.

FAQ
Common Questions
An SCR power controller is a silicon controlled rectifier, a controllable diode with support electronics, heat management, and safety packaging. SCRs can be used in a variety of applications to control the power, current and voltage to your load.
SCR controllers offer infinite resolution and features such as voltage compensation, current limiting, and Overcurrent Trip. SCR controllers are often less expensive and don’t have inherent wear-out modes

Control Concepts recommends protecting the SCR with a class T fuse, an excellent compromise between protection and premature fuse failure.
Yes, SCR power controllers generate harmonics on power lines, which may cause overheating of inductive equipment, such as transformers, motors, etc. However, actual occurrences of this issue are essentially non-existent.
Zero Cross controllers generate most harmonics below 50/60 cycles.
Phase Angle controllers generate harmonics above 50/60 cycles. For single phase controllers, the largest distortions occur at 3rd, 5th, and 7th harmonics. For three phase controllers, all multiples of the 3rd harmonic are not created.
Your production line needs precision, reliability, and quick answers always.
