Low Inrush Transformers : No external Components
POWERTRONIX offers a low inrush transformer for high power applications in addition to our regular versions. These designs are made to match the main breakers inrush capabilities or to meet pre-defined inrush requirements. Inrush suppression is inherently controlled, thus are no external components which means less field service, a longer shelf-life and an overall high circuit MTBF rate.
APPLICATIONS
These specific transformers are popular in the medical, energy and industrial power transformers. Applications are typically for power ratings of more than 1000VA.
Contact POWERTRONIX for design details
The following guideline calculation is based on input/output voltage 230/50Hz and temperature rise 60–65 deg C.
