OTi DALI 210/220-240/24 1-4 CH P Remarks

− Product performances below minimal load condition: the output power is still generated if the load is below the minimum output power (80 W on single channel or distributed), without any safety risk, but performances regarding THD, EMI, etc. are not guaranteed. See typical operation window graph for details.

− Output short circuit protection: short circuit current is limited without damaging the unit. The short circuit protection is self-restoring.

− Output overload protection: in case of overload (< 25%), the device automatically dims down the output to keep the power within 210 W and let the LED load to warm-up. When the overload exceeds the 25% of maximum nominal output power, the LED load will blink to manifest a fault condition.

− Lamp failure detection: minimum load per channel that doesn’t trigger open circuit detection is 30 W.

− No load operation: do not put a switch between ECG and load.

− Over temperature protection: the driver is protected against temporary overheating, so it automatically dims down when Tc is exceeded. The protection is self-restoring.

− Exit cables: the supplied, internally wired cables cannot be replaced; if the cord is damaged, the LED driver must be replaced.

− Waterproof: the driver is designed for outdoor installation with IP66 / IP67 protection grade. Input and output cables must be connected by means of a sealed cable clamp.

− Recommendations on how to dispose of it at the end of its life in line with Directive 2012/19/EU: separate control gear must be disposed of, in accordance with WEEE, at certified waste disposal companies. For this purpose, recycling centres and take-back systems (CRSO) collection points are available in the trade or at private disposal companies that accept separate control gears free of charge.
In this way, raw materials are conserved, and materials are recycled.

Other drivers stocked within the constant voltage outdoor dimmable range

OT 250/220-240/24 P

DALI constant voltage multi-channel LED drivers are advanced, addressable power supplies (typically 12V/24V) used for controlling multiple LED circuits—such as RGB, RGBW, or CCT strips—via the Digital Addressable Lighting Interface (DALI) protocol. These drivers allow precise, flicker-free digital dimming (0–100%) and individual channel control.

Key Features and Benefits

Multi-Channel Control: Enables individual addressing of up to 4 or more channels, making them ideal for color-changing (RGBW) or tunable white (CCT) lighting systems.

DALI-2 Compliance: Supports the latest IEC 62386 standards, offering improved compatibility with smart lighting control systems.

Constant Voltage PWM Output: Typically outputs PWM (Pulse Width Modulation) at high frequencies (e.g., 4KHz) to ensure smooth, flicker-free dimming for 24V LED tape.

Advanced Control Features: Supports scene setting, grouping, and addressing of individual fixtures, allowing for sophisticated lighting design.

Input/Output: Generally accepts 220-240V AC and converts to stable 24V DC.

Protection Mechanisms: Includes safety features such as short-circuit, overload, and over-temperature protection with automatic recovery.

Common Applications

These drivers are frequently used in commercial and architectural projects for:

• RGBW and tunable white LED strip lighting.
• Dimmable linear lighting in offices.
• Accent lighting in retail or hospitality environments.

Key Considerations

IP Rating: Available in IP20 for indoor use, or high-efficiency IP67 models for, waterproofing.

Power Output: Ranging from lower wattage options up to 240W-360W+ for extensive LED installations.

Installation: Must be installed by a qualified electrician, often supporting both DALI and “Push DIM” (manual wall switch) controls.

OSRAM Licht AG is a German company that makes electric lights, headquartered in Munich and Premstätten (Austria). OSRAM positions itself as a high-tech photonics company that is increasingly focusing on sensor technology, visualization and treatment by light.[3] The company serves customers in the consumer, automotive, healthcare and industrial technology sectors.[4] The operating company of OSRAM is OSRAM GmbH.

Osram was founded in 1919 by the merger of the lighting businesses of Auergesellschaft, Siemens & Halske and Allgemeine Elektrizitäts-Gesellschaft (AEG). Osram was a wholly owned subsidiary of Siemens AG from 1978 to 2013. On 5 July 2013, Osram was spun off from Siemens, and the listing of its stock began on Frankfurt Stock Exchange on 8 July 2013.[5] Osram’s business with conventional light sources was spun off in 2016 under the name Ledvance and sold to a Chinese consortium.[6]

After a bidding war[7] with Bain Capital, Osram was taken over by Austrian company AMS in July 2020.[8][9][10] Since then, the company has operated under the name AMS Osram.[11]

The name is derived from osmium and Wolfram, German for tungsten. Both elements were commonly used for lighting filaments at the time the company was founded.

In 2020 ams AG acquired the German lighting, LED, and opto-semiconductor manufacturer OSRAM. Since then, the company operates under the name ams OSRAM.

The ams OSRAM portfolio includes light emitters, sensors and CMOS ICs with embedded software solutions as well as lighting systems and specialty lamps for automotive, industrial and entertainment applications. The company mainly address the automotive, industrial and medical markets, as well as selected fields of consumer electronics.
