The LDALI-PWM4-x is a 4 channel constant voltage LED driver. It is suitable for constant voltage LED modules and LED strips with operating voltages from 12 to 24 V DC.

The module provides a wide dimming range from 0.1% to 100% and adjustable PWM frequency (125/250/500 Hz). The maximum load is limited by 3 A per channel. The module provides overtemperature protection as well as open- and short-circuit-protection for each channel.

From a DALI perspective, the channels can be controlled independently via separate DALI addresses. The LDALI-PWM4 module is compliant to the DALI specifications IEC 62386-101, IEC 62386-102 and IEC 62386-207 (Device Type 6,“LED”). Separate module types for tunable white (LDALI-PWM4-TC) and colour control applications (LDALI-PWM4-RGBW) support the DALI specification IEC 62386-209 (Device Type 8, “Colour Control”).

Features

• Easy integration into LOYTEC L-DALI lighting systems and LROC-40x room automation controllers
• Device configuration with the free LINX Configurator or via the built-in web server of the L-DALI controller
• Dimmable built-in constant voltage DALI LED driver
• Suitable for constant voltage LED modules and LED strips
• LDALI-PWM4: 4 PWM channels, each of which can be controlled independently via separate DALI addresses
• LDALI-PWM4-TC: 4 PWM channels, 2 of which are controlled via a DALI address (DT8 – Mode Tc), perfectly suited for tunable white luminaires
• LDALI-PWM4-RGBW: 4 PWM channels, controlled via a common DALI address (DT8 – Mode RGBWAF)
• Maximum current of 3 A per channel
• Dimming range from 0.1% to 100%
• Adjustable PWM frequency: 125 / 250 (default) / 500 Hz
• Externally powered, supply voltage 12 to 24 V DC according to the operating voltage of the LED modules
• High efficiency and low standby power consumption
• Overtemperature, Open- and Short-circuit protection
• DALI-2 certified, supporting IEC 62386-101, IEC62386-102, IEC 62386-207 and IEC 62386-209
• Firmware update via DALI
