AC drives control the speed of an electrical motor. Frenic-Mega, the Mega series AC drive from Fuji Electric (www.fujielectric.com), is designed for applications that run 24/7. It features insulated-gate bipolar transistor (IGBT) technology, built-in customizable logic functions, an EN 594 safety input, and corrosion protection for harsh environments.
“Fuji Electric’s Frenic-Mega series provides the industry’s highest-performance constant torque drive for three-phase motor applications,” says Terry Webb, engineering manager for AC Drives at Fuji Electric. “They offer expanded power ratings and flexible configurations that support 1/2 HP up to 1,000 HP AC.”
Corrosion buildup and associated costs are a major concern in heavy-duty vehicles. The new Sta-Dry QCMS2 plug/socket from Phillips Industries (www.phillipsind.com) is designed to eliminate corrosion damage caused by road contaminants entering the vehicle’s electrical system. The electrical cable has a Sta-Dry seal at one end for a corrosion-free connection, and a quick-change plug on the other that is designed to be repaired in the field in seconds. The QCMS2 corrosion-free housing is connected to the cable with a special bonding process.
“Phillips Industries has been an innovator in the heavy-duty truck and trailer industry for decades,” says Ron Fay, technical support specialist at Phillips Industries. “Corrosion is the number-one problem affecting the electrical systems today and Phillips Industries is on the forefront of Sta-Dry technology.”
