1. Introduction
Thank you for your interest in the eldoLED POWERdrive 50W DMX LED driver family. This design guide addresses common
design features, configurations, and performance considerations when designing a luminaire incorporating any one of the
following POWERdrive LED drivers
*
:
-
POWERdrive 50U-M4Z0X
-
POWERdrive 50S-M4Z0X (scheduled for release in a few weeks)
-
POWERdrive 50SA-M4Z0X (scheduled for release in a few weeks)
2. Electrical Design
Output Characteristics
A POWERdrive LED driver contains four constant-current LED outputs, that are specifically designed to power LED light
engines. It is not recommended to use a POWERdrive LED driver to power other electronic loads or circuitry; this may
cause unpredictable behavior and/or damage to the POWER LED driver.
Each LED output can support an LED load with a forward voltage up to 55V. The nominal output current for each LED
output can be programmed in 1mA steps between 150mA and 1400mA. Consult the product datasheet for detailed
information on the acceptable operating window of the driver.
The cumulative output power of a POWERdrive LED driver across all four LED outputs cannot exceed 50W. This power
does not have to be evenly distributed, i.e. each LED output can support a different forward voltage and forward current.
The LED outputs of a POWERdrive LED driver can be programmed to be controlled independently, grouped, or disabled.
Between 1 and 4 DMX addresses will be visible to the DMX network based on the programming of the driver. See the
Driver Configuration section for more detailed information.
The POWERdrive LED driver is designed to meet UL Class 2 requirements. This means that each LED output meets these
requirements:
-
Output voltage less than 60V
-
Output current less than 5A
-
Output power less than 100VA

The wiring diagrams in this Design Guide show the physical connector layout for POWERdrive 50U-M4Z0X. Nevertheless, the wiring
guidelines in this Design Guide apply to all the POWERdrive LED driver configurations listed here.
