Frequently Asked Questions

Can the ELG-200-C700AB drive a tunable LED downlight array that requires dimming control?

Yes. The ELG-200-C700AB combines adjustable output with analog dimming capability, making it suitable for LED downlight systems where dimming via a 0–10V or PWM signal is required. It delivers 700mA constant current with a CC voltage range of 142–286V, covering series-connected LED chains in typical downlight modules.

Is the ELG-200-C700AB appropriate for use in LED signage modules that need brightness adjustment?

Yes. The combination of adjustable output and built-in dimming on this 200.2W, 700mA constant current driver makes it practical for illuminated signage applications where brightness trimming is part of the installation. The IP65 rating protects the driver from dust and water jets in cabinet or channel-letter sign enclosures.

Can I use the ELG-200-C700AB in an LED retrofit project that replaces fluorescent high-bay fixtures?

The ELG-200-C700AB accepts 100–305VAC input and delivers 200.2W at 700mA constant current. It is well suited to LED retrofit high-bay fixtures where an existing dimming infrastructure (0–10V or PWM) will be reused. Ensure the LED modules selected have a combined forward voltage within the 142–286V CC range.

How many LEDs can the ELG-200-C700AB power in a series string?

The ELG-200-C700AB operates at a constant 700mA with a CC output voltage range of 142–286V. The number of LEDs that can be connected in series depends on the forward voltage of each LED at 700mA — there is no fixed count. Confirm your LED's Vf at the operating current and ensure the total string voltage falls within 142–286V.

What dimming methods does the ELG-200-C700AB support, and how does it differ from the ELG-200-C700A?

The ELG-200-C700A is adjustable only, with no external dimming signal input. The ELG-200-C700AB adds analog dimming (the 'B' suffix) to the adjustable ('A') feature, allowing external 0–10V or PWM dimming control. Both units share 200.2W, 700mA constant current, a 142–286V CC range, and IP65 rating.

Can the ELG-200-C700AB be used in damp or dusty industrial environments?

The ELG-200-C700AB is rated IP65, protecting against dust ingress and low-pressure water jets. It operates from -40°C to +85°C, making it suitable for damp utility spaces, light industrial facilities, or covered outdoor installations. For submerged or heavy washdown environments, an IP67-rated unit would be required.
