It dims 12 V or 24 V constant-voltage fixtures, such as dimmable LED bulbs and short LED strips. Connect mains and data, and all 64 outputs are ready.<\/p>\n<h2>Why use an SPI bulb dimmer?<\/h2>\n<p>Pixel controllers speak WS2811, but a dimmable LED bulb does not. Normally you combine a separate dimmer, an LED power supply and a lot of wiring between them. The Powered Bulb Dimmer puts all of that into one aluminium box. As a result, 64 bulbs become 64 individually controllable points in your show.<\/p>\n<h2>How the Powered Bulb Dimmer works<\/h2>\n<p>The unit reads differential 800 kHz SPI and turns each 8-bit value into a <a href=\"https:\/\/en.wikipedia.org\/wiki\/Pulse-width_modulation\" target=\"_blank\" rel=\"noopener\">PWM<\/a> level on one output. That gives 256 brightness steps per channel. The PWM runs at 2 kHz, so the light stays flicker-free on most video cameras. In addition, every output has its own self-resetting fuse.<\/p>\n<h2>Key details<\/h2>\n<ul>\n<li>64 open-drain outputs, up to 500 mA on a single channel<\/li>\n<li>12 V version: 12.2 A in total, 190 mA per channel when the load is spread evenly<\/li>\n<li>24 V version: 6.1 A in total, 95 mA per channel when the load is spread evenly<\/li>\n<li>Mains 85\u2013264 VAC on PowerCON in and through, 148 W rated power, 2 W self consumption<\/li>\n<li>SPI in and out on ESD-protected RJ-45, data runs up to 100 m on Cat5e<\/li>\n<li>Up to 48 units in one chain, so a four-output <a href=\"\/product\/lec-3\/\">LEC 3 PRO<\/a> drives 4 \u00d7 48 dimmers<\/li>\n<li>Aluminium enclosure, IP30, 243.5 x 93 x 105 mm, 1290 g<\/li>\n<\/ul>\n<h2>Which fixtures and controllers does it suit?<\/h2>\n<p>Wire single-colour bulbs or strips as 64 independent sections. Alternatively, group outputs for CCT, RGB or RGBW strips. <a href=\"\/product\/lec-3\/\">LEC 3<\/a> and <a href=\"\/product\/spi-matrix\/\">SPI MATRIX<\/a> drive it directly. Controllers without differential output, such as the <a href=\"\/product\/spi-led-controller\/\">SPI LED Controller<\/a> or REACTIVO 2, connect through <a href=\"\/product\/the-symmetrizer\/\">THE SYMMETRIZER<\/a>. For DMX, the SPI LED Controller offers pixel mode and SD card mode. Typical uses include events, clubs, theatre, scenography and showcases.<\/p>\n<h2>What comes in the box?<\/h2>\n<p>You get the dimmer, a PowerCON cable with a plug for your country and all 64 terminal plugs. Side tabs take screws, cable ties, clamps or a safety wire. A qualified electrician should carry out the installation.
