Marathon Power is pleased to announce its first battery-less Uninterruptible Power System. It is a state-of-the-art, double-conversion “UPS” that uses Supercapacitor technology for energy storage instead of conventional batteries.

The system is designed to provide short-term backup to sensitive loads in applications that either need to ride-through voltage sags and momentary power outages or simply bridge the start-up of a generator.

Since most power interruptions (87%) last no more than 1 second according to the Electric Power research Institute, there is seldom a need for long-term storage technology such as batteries. It is targeted specifically at applications that are sensitive to power disturbances that last from a few cycles to around one minute.

This most ‘Green’ of all UPS technologies offers numerous advantages over conventional UPS’s and other energy storage technologies such as flywheels and fuel cells. There is no battery replacement, system maintenance, hazard waste disposal or component recycling.

The system consists of 2 parts – the UPS Electronics module and the Energy Storage module.

The Electronics module is configured as a true-online double conversion UPS. This topology is ideal for the most critical applications where the best level of power protection is required. Connected equipment is not only immune to the slightest power fluctuations, but also other power anomalies such as spikes, surges, sags, swells, harmonics and frequency variations.

The unit features a wide input voltage tolerance, tight output voltage regulation and very low harmonic distortion. Twin microprocessors aid redundancy and an automatic bypass switch ensures that power to the load is not interrupted in the event of a system fault.

The Energy Storage module is a self-contained unit that consists of the Supercapacitors and their associated electronics. The module can be charged independently of the system.

The first model in the lineup is a 3000VA, 2100 Watt model at either 120V or 230V and a backup time of 15 seconds at full load and 45 seconds at half load. Recharge time is approximately 2 minutes but can be reduced with a suitable AC source. Other run times are available using additional energy storage modules or different Supercapacitor combinations.

The system features a user-friendly, multifunction LCD control panel that indicates the status of the system and allows the user to make parameter adjustments. Communication options include power-monitoring & system management software and SNMP capability.

One of the key applications is in healthcare where critical loads in this environment need support during the startup of an emergency generator. Another primary application is in the industrial automation market where relatively short holdup times will allow a process to continue uninterrupted. An example of this is the semiconductor fabrication industry where manufacturing equipment is required to meet semi F47 ride-through standards.
