Patent ID: 7181183

Claim:
A telecommunication system to generate electromagnetic transmissions and operating on power initiated from an AC source, comprising: telecommunication equipment including an antenna; a rectifier in electrical communication with the AC source and the telecommunication equipment, the rectifier to convert AC power to DC power; a VRB-ESS charger/rectifier in electrical communication with the AC source, the VRB-ESS charger/rectifier converting AC power to DC power, the VRB-ESS charger/rectifier to monitor received AC power to determine an AC power interruption; a VRB-ESS in electrical communication with the VRB-ESS charger/rectifier to receive DC power to thereby charge the VRB-ESS, the VRB-ESS further in electrical communication with the telecommunication equipment to provide DC power transmission to the telecommunication equipment; and a timer switch in electrical communication with the VRB-ESS charger/rectifier and the VRB-ESS to control DC power transmission from the VRB-ESS to the telecommunication equipment, the timer switch to receive a control signal from the VRB-ESS charger/rectifier indicative of an AC power interruption, the timer switch to wait a predetermined time period before enabling DC power transmission to the telecommunication equipment.
