Finder has introduced a range of light dependent relays, which have the ability to control lighting according to ambient light levels.
Expected to be of interest to designers of lighting control systems, the 10 Series relays feature an integral photoelectric sensor combined with light feedback compensation circuitry, which prevents the controlled lighting from ‘hunting’ on and off due to the perceived increase in ambient light when lights are automatically turned on.
This feedback capability is achieved by monitoring the effect of the controlled lighting over a ten-minute period, which ensures compatibility with slow starting gas discharge lamps. ON and OFF delay times are reduced to zero for the first three cycles, which aids set up and commissioning and reduces installation time.
The range includes both single-pole and two-pole output types rated at 16A, and also a miniature type, 10.51, with a single 12A output. The double output 16A 10.32 allows Live and Neutral switching, while model 10.41 has a single 16A NO output for Live switching.
All the relays in the series operate from either a 120V or 230V AC supply.
