ASTdim

INTELLIGENT LUMINAIRE POWER REDUCTION CONTROLLER

Device Description

ASTdim is an intelligent controller designed for power management of LED and conventional luminaires equipped with DALI or 1–10 V control interfaces. The controller enables automatic power reduction according to programmable time schedules, significantly reducing energy consumption while maintaining the required lighting performance.

ASTdim supports both DALI and 1–10 V control interfaces simultaneously, eliminating the need to select the active control method during installation. This makes the controller suitable for a wide range of new lighting installations as well as modernization projects.

Designed for installation directly inside the luminaire, ASTdim offers simple integration with existing lighting infrastructure while providing advanced energy-saving functionality.

Intelligent Power Reduction

ASTdim supports up to five independently programmable power reduction periods, allowing lighting output to be precisely adjusted according to traffic conditions, operating schedules, or project requirements.

Each programmable period includes:

  • Start time
  • End time
  • Power level

This approach enables substantial energy savings without compromising lighting quality, user comfort, or operational safety.

Flexible Lighting Control

The controller features two industry-standard lighting control interfaces:

  • DALI
  • 1–10 V

Both interfaces operate simultaneously, eliminating the need to configure or select the control protocol.

ASTdim also includes a 230 V AC trigger input, allowing integration with external devices such as motion sensors.

When the trigger input is activated, the controller immediately disables power reduction and restores the luminaire to full light output. Once the trigger signal is removed, the controller automatically returns to the programmed dimming level.

The controller is configured using a predefined power cycling sequence. Power reduction schedules can also be programmed locally using ASTmicro controllers and the mobile application or remotely via ASTgsm controllers using the web platform.
