Powered Bulb Dimmer – Dual Polarity
€550.00 excl. VAT
Special 64 channel dual polarity SPI dimmer with built-in power supply designed for dimming 31-33V dual polarity constant voltage (CV) fixtures with anti parallel LED diode connection
Description
It has 64 independent full H bridge outputs. This is ideal for LED fixtures like:
-Xmas lights with anti parallel LED diode connection (odd and even sections controlled)
-CCT LED bulbs with anti parallel LED diode connection
POWERED BULB DIMMER DUAL POLARITY is power supply with SPImas Dimmer in aluminum enclosure providing “out-of-the-box” solution for entertainment industry.
With its high PWM frequency it is flicker-free on most video cameras, however as it works on a polarity change principal it will always flicker even on brightness set to maximum.
Each output is controlled by first 16bit of 24bit SPI WS2811 signal . First 8bit is for PWM of one polarity and second 8bit is for PWM of other polarity.
