Twilight Switch TS-41-3.4 – Smart Control for Lighting, Blinds and PV Systems

The TS-41-3.4 twilight switch automatically controls devices within a light intensity range of 100 to 100 000 lx — ideal for advertising panels, blinds, photovoltaic systems, and solar-powered CWU control. It switches ON at dusk and OFF at dawn (or vice versa), depending on the configuration.

Users often apply TS-41-3.4 in solar installations to control domestic hot water (CWU) systems during high sunlight using relay contacts 2–3.

Applications of TS-41-3.4

Perfect for:

  • advertising and LED lighting,

  • blind and shutter automation,

  • photovoltaic and solar heating systems,

  • building and industrial automation,

  • sunlight-controlled water heating systems.

Construction and Components

Set includes:

  • TS-41 controller – non-flammable ABS (V0) housing, DIN-rail mount (35 mm, 1 module 18 mm),

  • External sensor (IP65) – non-flammable ABS housing with cable gland, designed for wall mounting (two screws included).

Sensor cable length up to 1000 m (2 × 0.5 mm²).

Key Features and Benefits

  • Adjustment range: 100–100 000 lx (logarithmic)

    • 100–1000 lx – for ads and lighting

    • 1000–10 000 lx – for blinds and shutters

    • 10 000–100 000 lx – for photovoltaic and solar control

  • High switching capacity: 16 A (4000 W) 250 V AC / 16 A (384 W) 24 V DC

  • Inrush current resistance: up to 100 A

  • Galvanically isolated NO/NC relay contacts – flexible wiring configurations

  • Proportional hysteresis for stable operation under varying light conditions

  • Activation delay (~60 s) prevents false triggering (e.g. from headlights or lightning)

  • LED indicators:

    • green – power supply present,

    • red (blinking) – threshold exceeded,

    • blue – relay switching status (1-2 / 2-3).

Installation and Use

  • Controller mountable on DIN 35 mm rail,

  • External sensor mountable on a vertical surface (2 screws included),

  • Recommended placement: east or southeast side, for optimal energy savings,

  • Avoid installing the sensor directly in a lamp’s light beam – it may cause cyclic switching.

Safety

Connection of the TS-41-3.4 twilight switch must be performed by a qualified electrician. Ensure proper circuit protection and compliance with electrical safety standards.
