LED
POWER SUPPLY
• DC power (12 to 48V dependant on version and LED loading)
nd
A limited power source approved to UL60950-1 2 Edition, CAN/CSA C22.2 No. 60950-
nd
1.07 2 Edition MUST be used, with an output voltage of 12 to 48V DC.
Such a power supply can be connected directly to the LED using the DC Input connector.
The pins on this connector are marked:
Positive input (12 to 48V DC dependant on version and LED loading)
Signal ground (0V)
Chassis ground (earth)
The power supply should be connected to the Positive and Signal ground inputs, ensuring
the polarity is correct.
The LED will consume 200W maximum with all channels fully loaded at full intensity.
GROUNDING
The LED is designed to be mounted on a grounded (earthed) DIN-rail and a dedicated Chassis
ground (earth) terminal is also provided which should be connected to a suitable earth.
STATUS LEDS
The Mosaic logo will illuminate when power is applied to the LED. The red LEDs on the top of
the LED indicate the unit's status:
Active: Indicates that the unit is functional.
DMX data: Illuminates when DMX data is being received.
RDM data:
Illuminates when RDM data is being transmitted.
Error: Flashes to indicate an error condition.
DMX THRU TERMINATION
If the DMX Thru connection is not being used to daisy-chain to other DMX devices then the
supplied termination resistor MUST be fitted to ensure data integrity.
DMX & RDM GUIDELINES
The LED is compatible with the DMX512, DMX512(1990), DMX512-A and RDM 1.0 standards
and care should be taken to ensure that your cabling, wiring topology and termination also
complies with these standards.
Such compliance is beyond the scope of this document but a good resource is "Recommended
Practice in DMX 512" by Adam Bennette which is available through PLASA and USITT.
