Spectra Wiring diagram
Introduction
Spectra LED Driver is an Intelligent LED Driver Designed for Colour Mixing Applications.
This Application Note (AN1 Spectra Wiring Diagram) provides technical information for the wiring connection and
mounting of the Spectra LED Driver (all models)
Spectra LED Driver has one input connector and four output connectors for LEDs connection and LED thermal
protection. It has also several connectors for communication and controls.
This document describes how to connect the Spectra LED Driver (DC Input, Output Channels, Communication
and Controls).
The last part of the document contains useful suggestions regarding the fixing of the Spectra LED Driver to the
host system.

DC Input Connection
Spectra LED Driver is powered by a DC Input. The DC Input Voltage comes whether from a AC-DC Power Supply
or from a low voltage DC bus. Refers to the Figure 3 or 4 for the DC Input connection polarity.
Please consult the Spectra datasheet for the Input Voltage and Current ratings.

The NTC can be mounted to the LED Board Assembly to realize a thermal feedback in order to have an Over
Temperature Protection of LEDs.
Up to 4 NTCs (one for each output channel) can be connected to Spectra, as showed in the figures 7 and 8.
See the Application Note 2 “AN2 Spectra Temperature Sense” for the correct NTC choice.

DMX/RDM Connection
Spectra LED Driver can work in the Stand Alone mode (only 1 Spectra is used), in the Master-Slave mode or can
be remotely controlled through the DMX/RDM communication. It has also several analog and digital
Input/Outputs for the display connection or for OEM Options.
DMX IN and DMX OUT Signals are available in the connector called “DMX” and showed in the figures 9 and 10.
The connection can be easily realized by using the DMX Cabling (available as optional); this cable can be ordered
apart (Code RHSM000175), as written in the Spectra Datasheet.

Display/Keyboard Connection
Spectra LED Driver can be used also with the Display/Keyboard that allows the setting of the main product
parameters.
The Display/Keyboard module is already included in the Model RSPT190-BWD and its is available as optional in
the models RSPT190-BWOD and RSPT190-OPEN, as showed in the Spectra Datasheet (Options section).
When the Display is used as optional, it can be connected with Spectra by using the dedicated Display Cable
(available as optional, Code RHSM000229), as showed in the figures 11 and 12.

Other Connectors
Spectra LED Driver has other connectors (AUX, IR1,IR2) not explained in this document, in fact it is able to work
with several Input/Output Sensors digital and analog. Moreover Spectra is able to receive the signal that comes
from InfraRed sensor.
All these connectors are intended for OEM uses or factory reserved; see the Spectra Datasheet, OEM Options
section.

Mounting Spectra LED Driver
Spectra is designed for convection cooled operation, therefore the LED Driver mounting does not require
heatsink. The mounting surface has to be flat and it can be metallic or plastic.
It is recommended to guarantee that the Ambient Temperature is within the range specified in the Spectra
Datasheet. The mounting position (vertical, horizontal) does not influence the temperature (TBV).
Spectra LED Driver is made to be fixed on a flat surface through 2 x M4 screws.
Figures 13 and 14 show how to mount the enclosed version models.
