LDALI-PWM4 DALI PWM Module

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

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

From a DALI perspective, the channels can be controlled independently via separate DALI addresses. The LDALI-PWM4 module complies with DALI specifications IEC 62386-101, IEC 62386-102, and IEC 62386-207 (Device Type 6, "LED"). Separate module types for tunable white applications (LDALI-PWM4-TC) and color control (LDALI-PWM4-RGBW) support DALI specification IEC 62386-209 (Device Type 8, "Color Control").

## Technical 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 L-DALI controller's integrated web server
- Integrated and dimmable DALI constant voltage LED driver
- Suitable for constant voltage LED modules and 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 one DALI address (DT8 - Tc Mode), perfectly suited for tunable white luminaires
- LDALI-PWM4-RGBW: 4 PWM channels, controlled via a common DALI address (DT8 - RGBWAF Mode)
- 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 from 12 to 24 V DC according to the operating voltage of the LED modules
- High efficiency and low standby power consumption
- Overtemperature, open-circuit, and short-circuit protection
- DALI-2 certified, supports IEC 62386-101, IEC62386-102, IEC 62386-207, and IEC 62386-209
- Firmware update via DALI
