Abstract: An integrated battery fusing device for a battery system of the type used as a backup for powering telecommunications equipment. The fusing device includes a fusing assembly and a terminal plate arrangement that integrally mounts the fusing assembly to the battery system. The terminal plate arrangement includes a first connector for electrically coupling the fusing assembly to the battery system and a second connector for electrically coupling a battery cable to the fusing assembly.

Abstract: A voltage regulator is disclosed for regulating the voltage supplied by an energy source such as a photovoltaic array. The regulator includes a thermally activated switch which is coupled in series between the regulator input and output. A control circuit monitors the voltage supplied to a load and generates a control signal which is responsive to the measured to the load voltage. A heater, responsive to the control voltage, is positioned near the thermally activated switch and causes the switch to open when the sensed voltage rises above a prescribed limit. Hysteresis in the voltage regulator is provided by thermal insulation which retards the dissipation of heat from the vicinity of the switch causing the switch to remain open.
