MST built-in constant-current rectangular LED modules, 519x261mm, nominal 2500lm/81V designation, for non-SELV series systems.
This 81V family is distinct from the 519x261mm SELV 48V family. Listed variants use CRI 80 CJ G4 at 3000K or 4000K; other CCT and CRI on request.
At 175mA nominal current, 71V forward voltage and 12W nominal power, the 3000K version delivers 2462lm at 198lm/W; the 4000K version delivers 2560lm at 206lm/W.
Operating current range 60-1500mA. Working-voltage rating 350Vdc; follow the series-connection diagram with a suitable non-SELV driver.
The luminaire enclosure must provide protection against electric shock. Mount on a flat surface without mechanical stress, maximum fixing torque 0.5Nm, and observe ESD precautions.
120° beam angle, 3 SDCM initial colour consistency and RG1 unlimited photobiological safety. Rated performance temperature 65°C; maximum safe case temperature 85°C. CE, ENEC, RoHS and REACH compliant.
Re-workable push-in terminals accept 0.2-0.75mm² solid or flexible wires, with an 8-9mm strip length.
No standalone IP rating; suitable protection must be provided by the luminaire or enclosing system.
