Uninterruptible Power Supplies (UPS)

Uninterruptible power supplies (UPS) provide battery backup to essential industrial equipment. Consult this block diagram to identify Littelfuse components that help ensure UPS operate on demand. We make MOSFET rectifiers, IGBT inverters, and several types of overcurrent, overvoltage, ESD, and reverse polarity protection.
