Description | Primary switch mode power supplies; for 753-647 DALI Multi-Master Module; DC 18 V / 1.1 A |
Remarks | Note:
The 787-1007 Primary Switch Mode Power Supply is specially designed to supply the 753-647 DALI Multi-Master Module. The 787-1007 features a 54mm-wide DIN-rail mount enclosure with input voltage ranging from 85 to 264VAC (120 373VAC). The power supply provides an output voltage of 18VDC and a maximum output current of 1100mA. This allows several DALI Multi-Master Modules to be supplied in parallel. The maximum current per DALI line is limited to 200mA in each DALI Multi-Master Module. - Supplies up to five 753-647 DALI Multi-Master Modules*
- Prepared for class II equipment
- Natural convection cooling when horizontally mounted
- Stage profile, ideal for distribution boards or distribution boxes
Output current Io: 1.1 A at 18 VDC max. 0.8 A (18 VDC) in any mounting position
External fuse: Wire breaking 10 A, 16 A, Characteristic B, CAn external DC fuse is required for the DC input voltage
