Circuit arrangement for powering at least one load |
摘要 |
A voltage control system for powering at least one remote load from a local power supply. A voltage control circuit coupled to the power supply produces a supply voltage which is transmitted to the load and is selectively set to any of a plurality of levels. A comparator at the load supplies back to the voltage control circuit an identification signal of a given type when the supply voltage is below a reference voltage level which can safely be applied to the load. The identification signal causes the voltage control circuit to change the supply voltage to a value which exceeds the reference voltage level but does not subject the load to overvoltage.
