Our LED luminaires are designed for standard dimming with a phase control rotary dimmer for electronic ballasts and any type of house wiring.
Both conventional 230V switch collections (flush-mounted box 68mm/depth 50mm) and our PLUG&DIM switch programme can be used with standard dimming.
For 1-10 V dimming with a rotary potentiometer, 1-10 V lighting control system, DALI lighting control system or CASAMBI, please contact your retailer.
LED STANDARD DIMMING WITH A PHASE CONTROL ROTARY DIMMER FOR ELECTRONIC BALLASTS
Tobias Grau LED luminaires can be dimmed from 100%-30% with a phase control rotary dimmer for electronic ballasts. This requires 3-core wiring with only 2 or 3 wires in the switch box. This further requires a rotary dimmer with push on/off function and a minimum load range ≤ 20 W. The possibility for subsequent fine adjustment of the minimum range should also be available. Tobias Grau luminaires and converters have been tested with phase control rotary dimmers for electronic ballasts from a wide variety of different manufacturers, however, the possibility of isolated malfunctions unfortunately can not be entirely excluded. In the majority of cases, such malfunctions are caused by the dimmer and not by the luminaire. We accept no liability in such cases.
Two-phase dimming, i.e. the dimming of two independent groups, spotlights and suspension luminaires for example, requires 5-core wiring in addition to a phase control rotary dimmer for electronic ballasts.
1-10 V DIMMING WITH ROTARY POTENTIOMETER
1-10 V dimming with a rotary potentiometer requires 5-core wiring and in addition that our LED luminaires / CHOICE FIXTURES must be equipped with 1–10 V ballasts. They can then be dimmed from 100% - 5% using a rotary potentiometer.
Two-phase dimming requires 8-core wiring and an additional rotary potentiometer.
DIMMING WITH A 1-10 V LIGHTING CONTROL SYSTEM
Dimming with a 1-10 V lighting control system requires 5-core wiring and an appropriate lighting control system, e.g. BUS, KNX, etc. In addition, our LED luminaires / CHOICE FIXTURES must be equipped with 1-10 V ballasts.
Two-phase dimming requires 8-core wiring and appropriate integration with the control system.
DIMMING WITH A DALI LIGHTING CONTROL SYSTEM
Dimming with a DALI lighting control system requires 5-core wiring and an appropriate DALI control system. In addition, our LED luminaires / CHOICE FIXTURES must be equipped with DALI ballasts.
Multi-phase dimming also requires 5-core wiring. It is achieved without rewiring via the DALI control system or DALI programming and is reflected in the corresponding extension of the control panel.
DIMMING WITH CASAMBI
With CASAMBI it is possible to use an app on a smartphone or tablet to dim Tobias Grau LED luminaires from 100%-5% with 3-core wiring with minimum two wires in a switch box. Groupings and lighting scenarios can be programmed, saved and retrieved as required. If a CASAMBI dimming module is used for 2 light sources, these light sources are depicted as one luminaire. Optionally, a wireless CASAMBI switch is also available and can be used to control up to 4 luminaires independently of one another.
The requirements for CASAMBI dimming are that our LED luminaires / CHOICE FIXTURES be equipped with 1-10 V ballasts and one of more CASAMBI dimming modules.
