Mean Well ELG-240-54A Power Supply | 240W 54V - Adjustable

Q: What does the A suffix mean on the ELG-240-54A?

The A suffix indicates the output voltage and current are adjustable via a built-in potentiometer. This allows the installer to trim the output within the specified range without external dimming control equipment.

Q: Can the ELG-240-54A be used in outdoor signage where only moderate moisture protection is needed?

The ELG-240-54A carries an IP65 water-resistant rating, which means it is fully protected against dust and against low-pressure water jets from any direction. It is suitable for enclosed outdoor signage and covered exterior luminaires but is not rated for submersion.

Q: How many meters of 54V LED strip can the ELG-240-54A drive?

The ELG-240-54A provides 240.3W at 54V and 4.45A. At a strip power density of 20W per meter, that supports up to about 12 meters; at 15W per meter it is approximately 16 meters. Always check your strip's rated wattage per meter and keep total load within 240.3W.

Q: Is the ELG-240-54A suitable for LED cove lighting in a hospitality environment?

Yes. The adjustable output allows fine-tuning of brightness during commissioning, which is useful in hospitality environments where designers specify a precise light level. At 240.3W and 54V, it can drive a substantial LED cove installation from a single unit.

Q: Can the ELG-240-54A operate from 277V input used in North American commercial buildings?

Yes. The input range of 100–305VAC covers 277V, which is common in North American commercial and industrial branch circuits. This allows the ELG-240-54A to be used directly without a step-down transformer.

Q: What certifications does the ELG-240-54A hold?

The ELG-240-54A is certified to c-BSI, CB, CCC, CE, EAC, ENEC, KC, c-RCM, and UL standards, covering the UK, international safety, China, Europe, Eurasian Economic Union, European ENEC, South Korea, Australia/New Zealand, and North America.
