STEINEL sumračni prekidač TTS PRO COM1 WS (089122)

With a robust 2000 W resistive switching capacity and zero-crossing technology, the STEINEL TTS PRO COM1 WS twilight switch delivers precise, relay-driven lighting control for demanding outdoor installations.

Overview

The STEINEL TTS PRO COM1 WS is a professional-grade dusk-to-dawn switch engineered for automatic lighting control based on ambient light levels. It features an integrated photo sensor with an adjustable lux range from 2 to 1000 lx, allowing fine-tuning for a wide variety of applications—from early evening activation to full darkness. The built-in time delay (2–10 minutes) prevents false triggering from transient light changes such as car headlights or lightning. The COM1 interface enables integration with remote control systems or building automation, making it suitable for both standalone and networked installations. Housed in UV-resistant white plastic with IP54 protection, it withstands outdoor conditions and can be mounted on walls, poles, or corners at heights between 1.8 and 2.5 m.

What stands out

• Zero-crossing switching reduces inrush current and extends relay life.
• Wide lux setting range (2–1000 lx) for precise activation thresholds.
• Adjustable time delay (2–10 min) prevents nuisance switching.
• COM1 interface for remote control and system integration.
• IP54 rated for dust and splash water resistance.
• Manual override possible via external switch or remote.
• Low standby power consumption (< 0.5 W).
