1.7kW Fuel Cell Battery Extender for Telecoms Backup Power and UPS Applications

Fuel Cell Battery Extender for Telecoms Applications

TECHNOLOGY

Dantherm Power systems are complete Backup Power solutions designed and configured to be installed in both in- or out- door applications for telecom and related networks. The solutions can be configured as both integrated and standalone modules.

The Battery eXtender uses hydrogen fuel cell technologies with fully integrated power management and various configurations possible.

WHERE TO USE BATTERY EXTENDER BACKUP POWER SOLUTIONS

The Dantherm Battery eXtender (DBX) is installed in parallel with batteries. The DBX is ideal in environments with an unstable mains (grid) where equipment must be protected from power outages and business continuity demands reliable backup power. In case of mains power outage the batteries will provide Backup instantly and the DBX-module provides support when the DC bus voltage drops or when a timer set point is reached.

FEATURES

Very low maintenance cost (site visits only required every 5 years)
Prevents batteries from deep discharge, thereby extending life
Very low noise, can be installed almost anywhere
No lead pollution and no harmful substances or emissions
Easy to increase Backup time to 8, 12, 24, 48 or even 168 hours or more
Compact, modular and scalable systems for network growth
Programmable Self-test ensures system readiness
Floating GND – can work in both -48VDC and +48VDC
Light weight. One module weighs less than one battery
Fuel storage in up to three strings for hot-swap and easy monitoring

CONFIGURATIONS

Mounts in 19” and 23” racks, 2 or 4 post cabinets/racks
Parallel with batteries and other modules for redundancy and higher capacity
Can be mounted in outdoor cabinets, shelters or similar
Easy to install on existing shelter sites
