Frequently Asked Questions
Can the ELG-240-48AB power a dimmable 48V LED strip installation in a hotel corridor?
Yes. The ELG-240-48AB combines output trim-pot adjustment with 3-in-1 dimming (0–10V, PWM, and resistance), making it fully compatible with wall-mounted 0–10V dimmers used in hotel and hospitality lighting. It delivers 240W at 48V for long corridor strip runs.
How many meters of 48V LED strip does the ELG-240-48AB support?
The driver outputs a maximum of 240W at 48V. For a 48V strip rated at 15W per meter, that allows 16 meters at full capacity (240 ÷ 15 = 16 m). For reliable continuous operation, work at 80% of rated output—192W—or about 12.8 meters at that strip density; confirm rated watts per meter for your specific strip.
Is the ELG-240-48AB suitable for an indoor commercial greenhouse with high humidity?
The ELG-240-48AB has an IP65 water-resistant rating, protecting against water jets and the high humidity levels found in commercial greenhouses. The -40°C to +90°C operating range accommodates both heated and cold-season greenhouse conditions.
Can I use the ELG-240-48AB to drive 48V LED strips in a retail store with scene-control dimming?
Yes. The built-in 3-in-1 dimming input accepts 0–10V, PWM, or resistance control signals, enabling integration with retail scene-control and automation systems. The 240W output at 48V is well-suited for display lighting across a mid-sized retail floor.
What is the difference between the ELG-240-48AB and the ELG-240-48A?
Both the ELG-240-48AB and ELG-240-48A output 240W at 48V with 5A and carry an IP65 rating. The ELG-240-48A provides output voltage and current adjustment via trim pots but no dimming signal input; the ELG-240-48AB adds 3-in-1 dimming (0–10V, PWM, resistance) on top of the same trim-pot adjustment capability.
Can the ELG-240-48AB be used for 48V LED strips in a stage or theatrical lighting rig requiring dimming control?
Yes. The 3-in-1 dimming interface—accepting 0–10V, PWM, or resistance signals—covers the control outputs common in theatrical dimmer racks and DMX-to-analog converters. At 240W and 48V, it can drive substantial stage wash or strip lighting loads.
