Power adapter for electrical installations and especially domestic installations
First Claim
1. A power adapter comprising:
- a power input (16)a plurality of power outputs (22, A, B, C, D, E),a load-shedding device (MC, 31, 32, IF, 37, PROG, MEM, RA, RB, RC), said load-shedding device including;
(a) means (MC) for detecting the current through the power input(b) means (31) for comparing said current with a threshold(c) means for successively disconnecting power outputs of said plurality in a pre-established order when said current is higher than said threshold and then successively re-connecting said disconnected power outputs in the reverse of said pre-established order when said current is lower than said thresholdprogramming means (PROG) for selectively assigning an erasure permission to at least one power output from said plurality independently of said pre-established orderinput means (56) for receiving a signal representing an external condition, anderasing means (37, PROG, MEM, IC, RA) responsive to said signal for selectively disconnecting said at least one power output upon detection of a predetermined condition of said signal,wherein said programming means (PROG) comprise means for programming said pre-established order and said programming means include a programation mode selector (62), for selecting between a load-shedding programmation mode and an erasure programmation mode.

Abstract
In order to optimize power supply costs and reduce billing rates in terms of prices charged per kilowatt-hour, the current consumed by a domestic installation is compared with a reference value and the result is transmitted to a microprocessor. As a function of this result, the microprocessor disconnects one or a number of power outputs in cascade and in a programmable order. In addition, the microprocessor receives a signal from one output of a relay which is responsive to rate-change data transmitted over the power distribution network at 175 Hz. When the billing rate is at a high price level, the microprocessor disconnects one or a number of outputs at the same time and as a function of a program established beforehand by the user.
