Shielded Super Isolation Transformer

.

Power Lines and Transformers

Power lines should be assumed to have transient voltages on them. In wiring an AC line to your electronics, employ devices which will isolate those electronics from the AC power line. Generally this will be a transformer. A transformer should be provided in the AC power connection to your electronics, even if no reduction in voltage is needed. It will be best if the transformer selected is an isolation transformer, designed especially to provide maximum isolation. If your installation is subject to severe voltage transients from the AC power line, (from variable speed motor drives, for example, or servo/spindle motor drive amplifiers), the double isolation technique illustrated here is strongly recommended.  

Business and industry is more dependent than ever on sophisticated electronics. Modern electronic control devices are frequently the most cost effective way to achieve real improvement in the performance of production machines and processes. Devices such as Computer Numerical Controls (CNC), Programmable Logic Controllers (PLC), as well as the various programmable motion controllers currently available for robotics applications offer unprecedented functionality and power, and are available at attractive prices.

Damage, Resets and Lost Data

Unfortunately, many owners who make the decision to retrofit these control devices do not achieve the full benefit of the upgrade. If your electronics are not properly installed and protected from electrical transients, one or more of the following may occur: 

·         Physical damage to the electronics.

·         Processor resets, leading to program interruption and/or (in the case of CNC devices) loss of machine position register information.Loss or corruption of program or data
