ABSTRACT:
Battery (300) includes a first redundant limiting circuit (302) for limiting the voltage and current levels which are outputted by the first limited battery output (308). A second redundant limiting circuit (304) provides for a second limited battery output (310). Connected to both the first (308) and second (310) battery outputs is a fault monitoring circuit (306), which monitors for any faults such as electrical shorts, occurring at any of the two battery outputs (308 or 310). The fault monitoring circuit (306) interrupts the appropriate output, if a fault, or a current limiting condition occurs. Battery (300) allows for radios which would otherwise not be able to achieve intrinsic safe level approvals to attain such approvals.
