The D4™ is a four circuit DALI / DSI BUS Power Supply. Rail-PSU-D4 outputs are designed to compliment the Rail-DALI-DMX, Rail-DMX-DALI, Rail-DSI converters. Users can power both from the same DC power supply in a power-through connection. Each circuit has two sets of connectors so the D4 can simply be daisy chained into each DALI / DSI bus. Red LEDs give power status. Green LEDs show data activity. Please note that a DC power supply is required for this product.
