Ultralife’s 120VAC X5 Power System is a reliable, hot-swappable uninterruptible power supply (UPS) that has proven itself in medical carts. It can utilize AC mains and Ultralife’s URB-X5 hot-swappable batteries to power devices up to 150W, such as desktop computers and printers.

Alternatively, for pole/mobile carts that need to power USB-C compatible devices (such as iPads/tablet PCs and laptops), Ultralife has developed the X5-SuperLite. Utilizing Ultralife’s URB-X5 hot-swappable battery, it can power up to two devices simultaneously. An optional hold-up battery maintains power during battery replacement and an optional state-of-charge indicator pendant gives easily accessible remaining run-time information.
