A power supply for standby circuits for an electrical consumer which separates both the electrical consumer and the power supply from the mains when in standby mode. The necessary power is supplied by a storage component backed up by an alternative voltage source. A voltage detector monitors the state of charge of the storage component and connects the circuit of the power unit to the mains as necessary. This power supply is suitable both for standby circuits of electrical consumers and for devices themselves or simply for control components and remote-control receivers on devices. Since a power unit is only connected to the mains when necessary, considerable energy savings are achieved.

DETAILED DESCRIPTION It is one object of the invention to provide an economical power supply for standby circuits of electrical consumers, such as remote control receivers, monitoring systems, battery charging devices and the like, which is operated without energy from the electrical power supply and is only connected to the electrical power supply when it is demanded by the consumer connected with it.
