​Danvers, Mass. – North American lighting leader OSRAM SYLVANIA continues to deliver technology innovation in the LED power supply market with the introduction of the linear constant current OPTOTRONIC® programmable 0-10V power supplies and OPTOTRONIC Step-DIM  power supplies. Designed for the OEM market, these LED power supplies offer tremendous design flexibility for a variety of general lighting applications.

“Our innovative LED power supplies offer unprecedented range of customizable settings and features that give OEMs the ability to design and tune the most appropriate solution for their luminaire and lighting application,” said Naveen Tumula, product group marketing manager, OSRAM SYLVANIA. “The OSRAM OPTOTRONIC family continues to deliver the flexibility and quality that our customers are looking for in today’s competitive landscape.”

Both families use the same slim linear form factor (11" x 1.2" x 1.0") and universal input voltage (120 - 277V AC, 50/60Hz). OSRAM OPTOTRONIC power supplies are UL Class 2 rated for safe operation and are covered by a 5-year warranty.

Programmable 0-10V Linear Power Supplies

Available in 30W, 48W and 50W versions, the OPTOTRONIC Programmable 0-10V dimmable, constant current LED power supplies feature one click programming via the OT programmer and output currents available up to 2000mA. Building upon the OPTOTRONIC Programmable platform, which allows for configuration of the output current with a 1mA resolution and LED thermal protection, this family offers several new OEM configurable features. These include end of life indication, constant lumen maintenance and an auxiliary output (12V, 20V and 24V) to power accessories and sensors, all programmed while not powering up or connecting the power supply to AC line voltage.

Ideal for indirect/direct, linear and recessed troffer applications, the power supplies are available with smooth architectural 1 percent or standard 10 percent minimum dimming through 0-10V dimmers, enabling direct integration and operation with standard dimmers and sensors as well as energy and light management systems.

Step-DIM Linear Power Supplies

Available in 30W and 50W versions, the OPTOTRONIC Step-Dim is a family of linear multiple output LED power supplies with bi-level power line dimming – 100 percent to 50 percent light output. The family offers an innovative, simple to use output current selection through the use of five fixed output current options per model. Bi-level dimming is realized through the use of two hot wire/AC positions. Both connections on equals 100 percent light output, while either one off equals 50 percent.
