Using DC Output Voltage for Controls
• Connect the DC output connector to the stem of the \Y” connector.
• Connect light-engine to one branch of the \Y" connector.
• Connect the pig-tail to the other branch of the \Y" connector.
• Connect the red (+out) and black (-out) wires to the controls per the control manufacturer's
instructions. The controls should be capable of operating with a supply voltage between 16-
22VDC and tolerate voltages up to 30VDC. The controls should not draw more than 50mA.
Control Inputs Description
There are two pairs of control input wires dimming-enable and dimming-control. The dimming-enable
wires (red and black) are used to enable and disable the dimming function. The dimming-control wires
(violet and gray) are used to change the light output from 100% to 50%.
Enabling/Disabling Dimming
To disable the dimming function, connect the red and black wires together. This can be done with a
wire connector (e.g. Ideal Weather Proof Wire Connector Nut 61 Blue/Orange). When the dimming is
disabled the light output stays at 100%. To enable the dimming function leave the red and black wires
open. The individual wires can be capped with a wire connector (e.g. Ideal Weather Proof Wire Connector
Nut 61 Blue/Orange). When the dimming is enabled the light output is controlled by the voltage on the
dimming-control wires In a multiple driver installation the dimming-enable wires of individual drivers need
to be kept isolated from each other. Connecting these wires between drivers may damage the individual
drivers.
Dimming
The step dimming function is performed by applying a positive voltage between the violet and gray
wires. A voltage from 12-24VDC sets the light output to 100%. A voltage from 0-1VDC will set the
light output to 50%. Multiple fixtures can be dimmed by paralleling the dimming control wires. Each set of
control wires typically draws 5mA at 24VDC (10mA maximum). The absolute maximum voltage for this
input is 30VDC. The maximum load of this input is 10mA (at 30VDC).
Powering Control Circuitry from the Driver Output
It is possible to power controls from the driver output. The driver output is typically 18-19V. An open-
circuit can produce voltages that are typically 26V. The control circuitry needs to operate at voltages in
the 16-20V and be tolerant of voltages to 30V.
Since the current of the luminaire is reduced by the currents drawn by the controls the loading should
be kept to a maximum of 50mA.
Using the Driver Output to Supply the Dimming Control Voltage
Since the driver output is within the dimming-control voltage range it can be used as a control voltage.
To tap the driver output connect a Y-cable to the output. Connect the luminaire input cable to
one side of the Y-cable. Connect a pig-tail to the other. The voltage between the red and the black wire
is 18V.
Connect the pigtail wires to the control circuitry using wire connectors (e.g. Ideal Weather Proof Wire
Connector Nut 61 Blue/Orange)
