Presidor™ Intelligent Power Control

Presidor™ Lighting Panels permit a selection of LED dimmers and relays in the same enclosure for highly efficient and cost-effective installations. DMX input with optional DIN rail node allows for broad application in two-panel sizes. Small panels are available in either 8 or 12 channels, while the large Presidor™ lighting panel supports up to 24 channels for larger installations. All options come with an optional splitter panel with a local 3-pole 40-amp disconnect breaker.

Panels can be custom-built with selected modules pre-installed at the factory in your chosen order. Module choices are dual relay, quad relay, or quad dimmer. Our Intelligent dimmers feature state-of-the-art reverse phase control, are rated at 600W, and support full-range dimming (1–100% DMX) for both LED and incandescent loads. Air-gap relays turn ON and OFF at selectable DMX thresholds ranging from 10% to 90%. 0-10VDC analog outputs can be programmed as a source or sink to permit direct drive of analog ballasts. Sensing protection on all circuits includes overload, short-circuit, temperature, over-voltage, inductive load, and more, ensuring circuit safety. LED indication and real-time error report back to the command control, providing advanced feature reporting that is typically only found in very expensive dimmers. The Presidor™ Command Controller delivers a full-color, capacitive touch GUI for easy setup and automatic error reporting. Smart capabilities and intuitive operation make these panels unique.
