The LDALI‑PWR1‑U is a DALI power supply for one channel with a guaranteed supply current of 50 mA (maximum supply current of 62 mA).
It is well suited as supply for small standalone DALI‑systems with a limited amount of DALI‑components or even for luminaire integration. A typical LOYTEC application is the supply of a DALI subsystem in a BT‑mesh ecosystem (e.g. for a room), in which the sensor acts as DALI application controller and gateway to the mesh ecosystem. However, the LDALI‑PWR1‑U can also be used only to supply the LOYBT-MSx Bluetooth multisensors.
In applications with higher DALI currents up to 4 LDALI‑PWR1‑U can be used in parallel, resulting in a guaranteed supply current of 200 mA (maximum supply current of 248 mA).
Installation
The DALI channel is treated to be non‑SELV (Safety Extra Low Voltage). Therefore the relevant installation regulations for low voltage apply. The cable of a DALI channel is either limited to a maximum length of 300 m using a minimum wire cross‑section of 1.5 mm² (AWG15) or must ensure a maximal voltage drop of 2 V.
Wide Range Supply Voltage
The power supply accepts a wide range of supply voltage from 85–240 V AC, 50/ 60 Hz, and also features a starting‑current limitation.
DALI Power Output
The DALI power output provides 16 V (11 V – 20.5 V) and 50 mA guaranteed supply current. The power output is isolated from mains by reinforced insulation. The power output is short circuit proof and shuts down if thermally overloaded.
The LDALI‑PWR1‑U is DALI‑2 certified.
