Description
The Eaton CST40AC consists of two 20-device AC charging towers that together provide secure, high-speed charging and organized storage for up to 40 Chromebooks, tablets, or mobile devices with screen sizes up to 16 inches. Ideal for classrooms, offices, healthcare facilities, and government institutions, these space-saving towers feature an open-frame design that allows quick visual inspection without unlocking the front doors.
Each tower is equipped with a dedicated 20-outlet PDU (NEMA 5-15R), offering 1440 watts of total charging power. Built from heavy-duty steel with a white powder-coated finish, the units ensure long-lasting durability and device security, complete with locking doors and top panels to prevent tampering. Integrated cable management keeps cords organized, while 10-ft. power cords provide flexible placement.
Designed for versatility, the CST40AC can be wall-mounted for stability or paired with the optional caster kit (CSTCASTERKIT20) for mobility between rooms. With flow-through ventilation, overcurrent protection, and numbered shelves for easy tracking, Eaton delivers a dependable charging solution that fits perfectly into crowded or collaborative environments.
