79471 Description

Short technical summary and product information.

The Osram 79471 LED Power Supply, part of the OPTOTRONIC series, is a high-performance driver delivering up to 85W of regulated constant current output. It operates across a wide input voltage range of 120V to 277V AC with a frequency range of 50-60 Hz.

 

This LED driver supports 0-10V isolated dimming, offering a dimming range from 10% to 100%. Key electrical specifications include an input current of 0.85A at 120V and 0.37A at 277V, with Total Harmonic Distortion (THD) below 20% and a power factor greater than 0.9 at full load. Efficiency is rated at a minimum of 85%.

 

Protection features include non-latching over-voltage protection, current fold-back over-load protection at 87W, and latching output short-circuit protection. It also incorporates LED thermal protection via an NTC sensor. The device is rated for an ambient operating temperature of -40°C to 40°C and is suitable for dry and damp environments.

 

Programmable features allow for adjustment of output current, dimming level, LED thermal protection, constant lumen output, and end-of-life indication. Programming tools include models 51645, 51647, and 51648.
