Detail

sunDial quad dmx 1k is a DMX/RDM controlled mains dimmer. Using trailing edge technology, the product provides smooth results with dimmable replacement LED, CFL or incandescent sources, with exceptional performance even at very low intensities. The product is rated at 250W per channel or 500W per pair of channels.

Custom dimming

sunDial quad is unlike any trailing edge dimmer currently found on the market. The product’s ultra-high resolution internal dimming allows the small window of useable LED lamp dimming response to be spread out over the entire DMX512 level range. There are four editable dimming curves that can be selected via RDM on a per-channel basis. Artistic Licence has also built a free database of lamp-specific dimmer curve files (see table below) that are automatically generated by our in-house photometric analyser. For ultimate control, customers can edit dimming curves and upload files (using DMX-Workshop, our free software management tool) to perfectly match chosen lamps (see the tutorials listed in the resources section below).

If you would like a dimmer curve generated for a specific lamp that does not appear in the database below, please see Dimming Curve Generation.

sunDial quad also offers operation in high resolution mode (14-bit), using two DMX channels per dimmer.

Advanced safety features

sunDial has been designed to be extremely resilient, with intelligent features that reduce ongoing maintenance needs. Active de-rating ensures that the product scales back if it approaches its maximum operating temperature. When the internal temperature sensors detect that it has cooled sufficiently, full operation is resumed.

Self-healing outputs shut down in response to over-current, short-circuit and over-temperature situations. Normal operation resumes without user intervention when the fault has passed.

Other smart features include preset and data loss modes.

Optional Xicato GalaXi control

For customers requiring wireless control – for example, in heritage buildings and retrofit applications where new data cabling would be problematic – we offer sunDial quad xgc 1k. This product variant supports Xicato GalaXi, in addition to DMX512/RDM. It retains all the functionality of the standard product. Wireless and DMX512 data are merged on an HTP basis. The sunDial quad xgc 1k is built to order, so please contact us at sales@artisticlicence.com for pricing and a lead time.

Optional mounting cabinet

Future Automation offer a range of custom installation enclosures for multiple sunDial units. Please click here for more information.
