1.0 Introduction
The Delta 3RU Series consist of four products that perform power distribution. Each model
accepts a single 3-phase power input and provides multiple single-phase outputs. All
products include RCD output protection, individual MCB per channel and power status
indicators. The power status indicators include “power available” to indicate the presence of
3-phase power, a “Neutral fault” indicator and a “Earth fault” indicator.
Two models also have integrated 5 way DMX512A compatible data splitters.
The Delta 3RU Series are built into a 3RU 19” rack mounted chassis and have a variety of
output connector options to suit installation requirements.
The DMX512A compatible models are supplied with a single 5 pin DMX input XLR plug with
push button termination and a pass-thru 5 pin DMX output XLR socket to allow more splitters
to be cascaded to increase the total number of DMX outputs. The single DMX input is
electrically isolated then split into five separately buffered DMX output circuits that are
supplied with three 5 pin XLR sockets and two 3 pin XLR sockets.
Visual indicators include a “DMX terminate” to show that the DMX input termination is
active; a “DMX data” indicator to show when DMX data is detected and a “DMX power”
indicator to show that power is available to the internal DMX circuitry.
All Delta 3RU data splitters have full input to output isolation, input and output EMI filtering
together with short circuit and overvoltage protection.
