Electromotive furniture drive for use as e.g. linear drive for furniture, has network activation device comprising switching element, which is connected in series with relay contact, and control block for controlling switching element

摘要

The drive has a network-bound control supply assigned to a control device, and a power supply device i.e. switching network part, comprising an operating state during disconnection of a network and an operating state during regular operation. A network activation device (8) has an auxiliary voltage source (20) i.e. transformer, and a network relay (23) with a relay contact (24). The network activation device comprises a switching element (25) e.g. relay or semiconductor switch, which is connected in series with the relay contact, and a control block (22) for controlling the switching element.
