OSRAM OPTOTRONIC Intelligent Compact OTi DALI 25/220-240/700 NFC LED Driver
Upgrade your commercial and architectural lighting infrastructure with the OSRAM OPTOTRONIC Intelligent OTi DALI 25/220-240/700 NFC. Designed as a compact, high-performance constant current LED driver, this unit combines digital lighting control (DALI) with rapid, contact-free configuration via Near Field Communication (NFC). Whether you are retrofitting commercial office spaces, setting up retail display lighting, or installing smart building systems in Malaysia, this OSRAM driver provides unmatched flexibility, energy efficiency, and operational safety.
Key Features & Engineering Highlights
1. Dual Programming via DALI & NFC Technology
Setting up lighting scenes has never been faster. The OTi DALI 25/220-240/700 NFC allows electrical contractors and system integrators to configure output current wirelessly using NFC tools or directly through standard DALI lighting management software. Current output can be set precisely between 180 mA and 700 mA (factory default set to 500 mA), giving you complete control over LED fixture brightness, power consumption, and thermal management.
2. Superior Power Quality & Efficiency
Built for demanding electrical environments in Malaysia and region-wide, this driver operates reliably across an AC input range of 198 V to 264 V (50/60 Hz) and DC input range of 176 V to 276 V. Key electrical properties include:
-
88% Peak Efficiency: Reduces ambient operational heat and overall energy costs.
-
Power Factor > 0.95: Ensures minimal reactive power consumption in large-scale commercial installations.
-
Low Harmonic Distortion (THD < 10%): Protects surrounding sensitive electronics from power line interference.
-
Ultra-Low Standby Power (≤0.1 W): Fully compliant with modern green building standards and networked standby energy directives.
3. Human-Centric, Flicker-Free Illumination
Light quality directly affects human wellbeing and visual comfort. The OSRAM OTi DALI 25 delivers stable, ripple-free current with an output ripple (100 Hz) of less than 3%, a PSTLM ≤1, and an SVM ≤0.4. This virtually eliminates visible and stroboscopic flicker, making it perfect for office workstations, educational facilities, healthcare facilities, and video recording environments.
4. Complete SELV Safety & Isolation
Electrical safety is paramount in modern installations. The driver features complete SELV (Safety Extra-Low Voltage) galvanic isolation across primary/secondary circuits, DALI/mains connections, and DALI/output lines. With a working voltage ceiling (U OUT = 60V), it prevents shock hazards and safeguards LED modules against transient voltage spikes up to 2 kV (L/N-Ground) and 1 kV (L-N).
