Supercap energy storage helps reduce long-term costs of UPS

The XLM Supercapacitor Energy Storage Module provides fast discharge for bridge events in uninterruptible power supplies for mission-critical applications. The module offers a reliable alternative to lead-acid batteries and is designed to be maintenance-free for grid storage and backup power applications. It is designed to improve power quality for critical applications during voltage spikes and brownouts. The module enables graceful shutdown of systems, and provides the ability to ride through power transients such as sags, spikes, and dropouts in order to smoothly transition to permanent backup solutions such as fuel cells or diesel generators. The module contains 69-Wh and the ability to discharge 7,800 A.

The XLM module is self-contained, housing 23 individual XL60 supercapacitor cells. The module discharges instantaneously for typical periods from 0.5 to 40 s. The supercapacitor-based module offers an operating lifetime up to 20 years and virtually unlimited charge and discharge cycles. It features integrated cell voltage balancing and is designed so that no monitoring or user controls are required. The 62-V, 130-F, 6-mohm module is offered in a 4U height by 6.9-in. wide size, can be rack-mounted in standard 19-inch equipment racks or 23-inch UPS racks. Connectors are located on the front so modules can be integrated into series for higher voltage or in parallel for longer time configurations. Prices start at $1,396.50 in quantities of 1.
