Frequently Asked Questions
Can the ELG-150-48A be used to drive 48V LED strips in a covered outdoor pergola or canopy?
Yes. The ELG-150-48A carries an IP65 rating, protecting it against dust and low-pressure water jets, which suits covered outdoor environments such as pergolas or canopies where rain splash may occur. Its 150.2W at 48V supports substantial strip loads in these applications.
What does the adjustable feature on the ELG-150-48A allow me to do?
The A suffix indicates the ELG-150-48A has a built-in trimmer potentiometer that allows field adjustment of the output voltage and current within the specified range, without requiring any external control signal. This is useful for fine-tuning LED brightness or matching the driver to specific LED module forward-voltage requirements on-site.
How much 48V LED strip can the ELG-150-48A power?
The ELG-150-48A outputs 150.2W at 48V with a 3.13A maximum. For a strip rated at 12W/m, that is approximately 12.5 m (150 ÷ 12 ≈ 12.5); for a 20W/m high-output strip, about 7.5 m (150 ÷ 20 = 7.5). Always confirm your strip's actual rated power per meter and apply appropriate derating for continuous operation.
Is the ELG-150-48A suitable for powering 48V LED panels in damp indoor environments like commercial kitchens?
Yes. The IP65 rating on the ELG-150-48A provides full dust protection and resistance to water jets from any direction, making it appropriate for damp indoor environments including commercial kitchens or food-service areas where splashing or cleaning occurs.
Can the ELG-150-48A operate in cold storage or refrigeration lighting applications?
Yes. The ELG-150-48A is rated to operate from -40°C to +90°C, covering the temperature ranges found in cold storage and refrigeration environments. The IP65 sealed case also handles the condensation that can occur in these settings.
How does the ELG-150-48A compare to the ELG-150-48 for an indoor commercial installation?
Both models share the same 150.2W, 48V, 3.13A output and physical dimensions. The ELG-150-48A adds a built-in trimmer for output adjustment, making it more flexible for commissioning. The trade-off is that the A variant is rated IP65 rather than the IP67 of the base ELG-150-48, so for fully outdoor or submersion-risk environments, the ELG-150-48 offers higher ingress protection.
Can the ELG-150-48A be used as a constant-current driver for 48V LED modules in retail display cases?
Yes. The ELG-150-48A operates in constant-current mode at 48V, which is compatible with 48V LED modules used in retail display cases and showcase lighting. The field-adjustable output also allows fine-tuning of light output during fixture commissioning without changing components.
