Delta PowerGen 15kW/25kW is an outdoor -48VDC standby generator designed to support telecommunications network power through extended utility power outages. Using 2.2 liters naturally aspirated 4-cylinder compact package engine, it's powerful but quiet. Delta PowerGen 15kW/25kW installation and deployment is quicker, easier and less costly than a traditional AC generator. Its availability can be assured through remote web browser access as well as M2M automation using SNMP alarms, polling and exercise.
