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
