Frequently asked questions
1. Which dimming controls does ELG-100-48AB support?
The AB version supports a 0–10V DC signal, a 10V PWM signal or resistance through its 3-in-1 interface. Follow the dimming wiring instructions in the PDF.
2. Is the ELG-100-48AB a 100W driver at every input voltage?
Its model rating is 96W at 200–305VAC and 70W at 100–180VAC. Apply the static-characteristic curve between these bands.
3. Is the AB version IP67?
No. The ELG-100 AB function version is IP65. It combines internal potentiometer adjustment with external dimming.
4. Can it continuously run from 360VAC?
The continuous input range is 100–305VAC. The specification’s higher-voltage withstand durations must not be treated as normal continuous operation.
