Potentiometers

n Principlen An electronic circuit generates voltage between 1 and 10 Vdc,

that depends on the mechanical position of a rotary knobn The circuit is powered by the controlled devicen The potentiometer has a built-in switch for switching mainsn There are two types:

LPS 100/00 rotary potentiometer for recessed mountingLPS 100/01 rotary potentiometer for surface mounting

Light regulators(Dimmers)

• LRD 8000 light regulator of the phase cut-in type, for:. GLS + high volt halogen. low volt halogen with conventional transformer

• LRD 8010 light regulator of the phase cut-off type for:. GLS + high volt halogen. low volt halogen with electronic transformers

• characteristics: . maximum load 1000 VA/230V. control voltage 1 - 10 Vdc. control current 0.5 mA (sourcing). control curve light output linear to control

voltage (GLS)

Dimming/RegulatingPrinciple• Variation of the

light output, using . regulating HF ballasts. light regulators

• Control voltage: 1 to 10 Volt dc signal

• Control current: . generated by ballast (current sourcing). absorbed by controller (current sinking)

• Control capability the total current sourced, must be lowerthan the maximum current sinking.

System features

In addition

• Password security (4 levels)

• Logging of luminaire hours run

• individual output report

• Emergency lighting test

• individual luminaire report

• Remote control ( hand held controller )

• Interfacing with other systems • interfacing inputs and outputs ( volt free contacts)

for example•Essential lighting

•with generator working, non essential lights are shut down to make sure that the generator is not overloaded

• fire detection system• with fire detection escape route lighting is switched on

• security•a zone will be lit when there is a break in

System benefits
