Selecting a Controller?
Please provide the following information, if known:
- Load voltage and phase ( i.e. 480V and three phase)
- Load configuration (delta, wye, etc.)
- Full load rating in amps, kW (kVA), or resistance
- Load type (i.e. nichrome, silicon carbide, graphite, or transformer-coupled)
- Control type (Zero Cross or Phase Angle)
- Command signal (4-20mA, 0-5Vdc, 0-10Vdc, digital, etc.)
- Digital communication requirements, if applicable (i.e. Modbus TCP RTU, Modbus TCP, EtherNet/IP, PROFINET, etc.)
- Required certifications such as UL, CE, RoHS, or SCCR
Common Questions
An SCR power controller is a silicon controlled rectifier; think 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
Please visit our product selector page or support to contact our team of experts. For fastest service, please have the following information available:
- Voltage
- Single or three phase
- Load current and type
- Command signal
- Other features
For more information, please visit our How to Order page.
Control Concepts recommends protecting the SCR with a class T fuse, which is 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.
When failure isn’t an option, work with engineers who understand what’s at stake and are ready to help.
