LDALI-PD1 Phase-Cut Dimmer Module
The LDALI‑PD1 module enables the control of phase‑cut dimmed consumers via a DALI channel. Typical application scenarios are the integration of 230V LED-retrofit‑bulbs or halogen lamps in DALI lighting applications.
The device supports a wide voltage range from 220‑240 V AC 50/60Hz. The LDALI‑PD1 is suitable for loads from 1VA up to 150VA. The load type (RL/RC) is automatically detected and used to select a suitable dimming‑method (leading or trailing edge phase‑cut). The dimming range is 3%‑100%.
The integration of the module in the DALI network follows the same simple steps as the integration of a DALI lamp. The device supports the DALI‑specification IEC 62386‑205 (Device Type 4, “Incandescent lamp”). The LDALI‑PD1 modules are directly connected to a DALI‑channel and also supplied with energy by that channel. Thus in case of a system failure the intended state of the output is off.
The LDALI‑PD1 is equipped with an open‑circuit detection that indicates a lamp failure if no load is connected.
The LDALI‑PD1 is designed for installation in distribution boxes or behind standard plugs in installation boxes.
