Dusk sensor with external probe Maclean Energy MCE34, 230V, 2300W, IP65 probe, LED compatible

Maclean Energy MCE34 is a dusk (twilight) sensor with an external light probe rated IP65 for outdoor use. The device is designed for direct connection to 230V mains and can switch resistive and inductive loads up to 2300W. It is suitable for controlling lighting circuits and is compatible with LED lamps, enabling automatic on/off switching based on ambient light levels. The separate probe allows flexible placement for reliable detection of exterior illumination conditions while the main unit remains in a protected location.

Advantages

The external IP65 probe provides moisture and dust protection for accurate light sensing in outdoor environments. Compatibility with LED lighting ensures stable operation with modern low-power lamps. The 2300W switching capacity supports multiple fixtures or higher-power luminaires, and the 230V supply makes the sensor suitable for standard mains installations. The separate probe and compact main unit simplify installation and positioning for optimal detection.

Suitable for

• Automatic control of external lighting such as garden lights and pathway luminaires
• Street and parking area lighting where dusk/dawn switching is needed
• Security and perimeter illumination to switch on at low ambient light
• Retrofit or new installations using 230V mains and LED fixtures

When it may not be suitable

This dusk sensor is intended for use with 230V mains systems; it is not suitable for low-voltage installations without an appropriate transformer. Because the probe provides binary switching based on ambient light threshold, it is not designed for dimming control or for applications requiring precise continuous light level adjustment.

Key specifications

• Operating voltage: 230V AC
• Maximum switching load: 2300W
• External light probe protection rating: IP65
• Designed compatibility: LED lamps and conventional lighting
• Sensor type: dusk/twilight light sensor with external probe

How to use

Install the main unit in a protected location near the lighting circuit and mount the external IP65 probe where it can reliably sense ambient outdoor light without being directly illuminated by the controlled fixtures. Connect the sensor to the 230V supply and the load according to the wiring diagram supplied with the unit, ensuring power is switched off during installation. Adjust the probe position to avoid shadows or artificial light sources that could affect switching. After connection, the sensor will switch the load automatically when ambient light crosses the integrated threshold between day and night.

What to consider before purchase

• Confirm compatibility with your mains supply (230V) and the total load does not exceed 2300W
• Ensure LED or other lamp types used are compatible with switched operation (no dimming required)
• Plan probe placement to avoid direct illumination from the controlled lights or other artificial sources
• Verify environmental exposure and mounting options for the IP65-rated probe

Usage recommendations

For reliable operation place the external probe in a location representative of ambient conditions, away from direct light emitted by the controlled fixtures and street-level glare. Regularly inspect the probe and connections for ingress or damage in harsh environments to maintain consistent switching behavior.
