Abstract:
1. A wiring device having line voltage alternating current (AC) and low voltage class 2 power receptacles, comprises: an electrically insulated housing; a mounting strap attached to the electrically insulated housing and adapted to secure the housing to a branch circuit outlet box; an AC receptacle having a hot contact coupled to a hot AC connection terminal, a neutral contact coupled to a neutral AC connection terminal, and a ground contact coupled to a ground AC connection terminal in the insulated housing; a ground-fault circuit interrupter (GFCI) coupled between the AC receptacle and the AC connection terminals so that if a ground fault event occurs the GFCI will disconnect the AC receptacle from a source AC voltage connected to the AC connection terminals; an AC line to low voltage direct current (DC) power supply having an AC input coupled to the AC receptacle and a low voltage DC output; at least one class 2 power receptacle coupled to and receiving power from the low voltage DC output of the AC to low voltage DC power supply, wherein the at least one class 2 power receptacle provides voltage and current for charging a battery in a portable battery operated electronic device; and a sleep mode circuit for placing the AC line to low voltage DC power supply, that supplies power to the at least one class 2 power receptacle and is coupled to the at least one class 2 power receptacle, into a low power sleep mode when substantially no current is being drawn through the at least one class 2 power receptacle to substantially reduce vampire power drawn by a load coupled to the at least one class 2 power receptacle.
