CP Electronics DD (direct dimming) sensors provide daylight harvesting, occupancy sensing and manual dimming straight from the sensor!
The installation of a DD 230V sensor, and a couple of press mechs, will allow control of up to 10 DALI or DSI ballasts (up to 20 if the relay is disabled).
The extensive range of direct dimming sensors includes flush or surface mount options, high bay sensors, batten mount variants, even models designed for low temperatures such as cold stores.
The CP Electronics range includes both PIR (passive infrared) and microwave detectors which will automatically turn the lighting on once someone enters the area. When the area is vacated, after a pre-set time delay, the lighting is turned off.
The built in light level (lux) sensor will keep the artificial lighting off if there is sufficient natural light available, or allow dimming of the artificial lighting to ‘top up’ when natural light levels are not high enough. Both step-down illuminance and maintained illuminance (daylight linking or daylight harvesting) can be provided straight out of the sensor.
PIR sensors are ideally suited to smaller rooms or where a defined detection pattern is required (for example, in between racking in warehouses). The passive infrared sensor detects body heat and movement.
With detection ranges up to 30 metres, microwave detectors are ideal for controlling lighting (or heating + ventilation) over large areas. With no external lenses, microwave sensors are unobtrusive and vandal resistant. No external control boxes are required, making the units both cost effective, and easy to install. Microwave sensors are sensitive to movement.
Dependent on the model, both PIR and microwave sensors can handle up to 10A loads, and are suitable for all lighting types. Time delays can be adjusted to up to 99 minutes. Each sensor functions with pre-set parameters straight ‘out of the box’ but these parameters (lux level, time delays, sensitivity) can be adjusted using a simple programming handset. A user handset is also available to allow client control of on/off, lux levels and preset scenes.
DD sensors can also be programmed to allow for required ‘lamp burn in’ times before dimming commences.
For a simple, standalone dimming solution, a press mech switch can be wired to the sensor, allowing manual on/off, dim up/dim down.
Analogue dimming (1-10V) also available, via the -AD variant of each sensor type.
