OPTOTRONIC OTi 50W Linear LED Driver 2743Y9 Constant Current

Description

Product Overview

The OPTOTRONIC OTi 50W LED driver is engineered for precision and flexibility in demanding lighting environments. With a universal input range of 120‑277 V, this linear driver fits seamlessly into existing power infrastructures while delivering a finely tunable constant current output from 600 mA to 1400 mA in 1 mA increments. The default setting of 1050 mA provides a balanced starting point for most applications, but the programmable nature allows users to tailor the output to the exact needs of their LED arrays. Constructed with a slim, durable chassis, the driver meets UL Class 2 output standards and holds UL Listing (E320395) as well as FCC Part 15 Class A compliance, guaranteeing both safety and electromagnetic compatibility. Its robust design is rated for both dry and damp locations, making it suitable for a wide range of industrial and scientific installations.

Usage

Designed with additive manufacturing professionals in mind, the OTi 50W driver excels in 3D printer lighting modules where consistent illumination is critical for accurate part inspection and post‑processing. The driver also serves well in laboratory benches, equipment enclosures, and any linear lighting system that demands low‑flicker performance. Its compatibility with DALI‑2, D4i, 0‑10 V, and LEDcode protocols enables seamless integration into existing building automation systems, while the optional Casambi and Atrius Bluetooth accessories provide wireless control for IoT‑enabled smart lighting projects. Whether installed in a cleanroom, a workshop, or a humid environment, the driver’s UL Class 2 rating ensures safe operation without the need for additional protective devices.

FAQ

Can the driver be programmed without connecting to mains power?

Yes. The OTi 50W driver includes a non‑volatile memory that can be configured via its USB interface while the unit is offline, eliminating the need for live power during setup.

What protection features are built into the driver?

The driver offers LED thermal protection, over‑current limiting, short‑circuit protection, and an end‑of‑life indication that automatically reduces output as the LEDs age.

Is the driver suitable for use in humid or damp locations?

Absolutely. The driver is rated for both dry and damp environments and complies with UL Class 2 standards, making it safe for installation in areas with elevated moisture levels.

How does the driver maintain constant lumen output as LEDs age?

Through its Constant Lumen Maintenance algorithm, the driver monitors forward voltage changes and adjusts the current to preserve the original light output, extending the useful life of your lighting system.

What warranty and support options are available?

All OPTOTRONIC OTi drivers come with a two‑year limited warranty covering manufacturing defects, and our technical support team is available via phone, email, and online chat to assist with any installation or programming questions.
