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 offers a different solution: Zero Cross Transformer (ZCT) Mode. This firing mode is a cost-effective way to eliminate harmonics/power factor issues without compromising performance, quality, or reliability. ZCT Mode is commonly used in the field for excellent results.
Are you a good candidate for ZCT Mode?
- Do you want improved power factor?
- Do you use transformer-coupled loads?
- Do you have high thermal inertia OR require less stringent process control?
