Electrical device i.e. computer, for use in e.g. office, has power supply unit shifted from hard-off mode into on-mode and vice versa, where electrical device operates control device in hard-off mode independent of supply network

摘要

#CMT# #/CMT# The device has a detachable power supply unit triggered by an operating action or by a device internal control process, and shifted from a hard-off mode into the on-mode and from an on-mode into the hard-off mode. The electrical device is designed to operate a control device in the hard-off mode independent of a supply network. A switching unit is controlled by a control impulse, and energy is obtained from a supply voltage source (2) of the electrical device. A standby-mode is provided during transition from the on-mode into the hard-off mode. #CMT#USE : #/CMT# Electrical device i.e. computer, for use in home and office. #CMT#ADVANTAGE : #/CMT# The power supply unit is shifted from the hard-off mode into the on-mode and from the on-mode into the hard-off mode, and the electrical device is designed to operate the control device in the hard-off mode independent of the supply network, thus reducing the energy consumption of the electrical device in the off mode in a simple manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a circuit representation of an electrical device. 1 : Circuit breaker 2 : Supply voltage source 3 : Load 4 : Auxiliary supply source 5 : Housing.
