Staircase Light Delay Switch

Guangzhou Depu Intelligent is a supplier for Theben. The ELPA8 staircase delay switch is primarily used for delayed lighting activation in stairwells. The product features a standard DIN rail mounting size of one module, available in three-wire and four-wire connection specifications.
It supports re-triggering functionality, has no closed-circuit current consumption, includes a manual normally open function, and operates via a synchronous motor drive. The internal precision mechanical design ensures accurate and stable operation with strong anti-interference capability.
The ELPA9 model follows a three-wire wiring specification and does not include an auxiliary switch.
The ELPA1 is an electronic staircase delay switch with zero-voltage protection, capable of handling higher loads. It allows direct setting of 10 functional modes on the panel, supports multi-voltage input AC/DC 8–240V, and features a power-off pre-notification function to prevent sudden darkness in the environment. Long-pressing the button enables further function settings, instant restart of the switch, or preset switch-off time. It operates via electronic drive switching.
The ELPA6 has the same specifications as the ELPA1 but lacks multi-voltage input.
The ELPA3 includes additional electrical isolation for multi-voltage input AC/DC 8–240V, instant restart functionality, and is equipped with a fixed switch switching mechanism.
