Control Concepts provides repair and maintenance services for ERC Controls legacy and current drive and control products, with particular strength in DC drives and related systems. Many ERC components remain in active use, and our technicians apply precision diagnostics, repairs, and part replacement to prolong reliability.
Who is ERC Controls?
ERC (Electric Regulator Corporation) was founded in 1945, evolving from the Electric Regulator Division of Ward Leonard to an independent company.
They pioneered SCR (silicon control rectifier) DC drive control in 1959 and have since expanded to IGBT-based AC and DC drive technologies.
ERC continues to offer a full line of AC and DC drives, components, and accessories.
What Do ERC Products Do?
ERC products are designed to govern the speed, torque, and direction of electrical motors under demanding industrial conditions. Common applications include:
- Statohm DC Drives — Precision control of DC motors, including feedback regulation and adjustable acceleration/deceleration.
- IGBT AC Drives — Modern variable frequency drive solutions for AC systems (ERC offers AC drive lines alongside DC).
- Drive Components & Accessories — Includes regulator cards, feedback modules, fuses, and electronic parts to support drive systems.
Control Concepts has experience diagnosing, repairing, and replacing these products to help extend service life and maintain uptime.
