<p>PCT No. PCT/CH94/00197 Sec. 371 Date Jun. 9, 1995 Sec. 102(e) Date Jun. 9, 1995 PCT Filed Oct. 4, 1994 PCT Pub. No. WO95/10875 PCT Pub. Date Apr. 20, 1995A 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.</p> |
