Its 40W output platform is rated at 15V and 2.67A, while the A-Type configuration provides built-in adjustment for both output voltage and current.\u003c\/p\u003e\n\u003cp\u003eThe HLG-40H-15A accepts a wide 90-305V AC input range and uses a fanless metal housing for free-air convection cooling. With an IP65 rating for the A-Type version, built-in protection functions, and a -40°C to +80°C case-temperature operating range under specified conditions, it is suited to demanding indoor and outdoor LED lighting installations.\u003c\/p\u003e\n\u003ch6\u003eApplication Scenarios\u003c\/h6\u003e\n\u003cp\u003eThe HLG-40H-15A is intended primarily for LED lighting systems that require controlled DC power rather than a conventional desktop-style AC adapter. Typical applications include architectural lighting, outdoor LED fixtures, signage, display lighting, commercial lighting equipment, and other LED systems designed around a 15V-class driver.\u003c\/p\u003e\n\u003cp\u003eThe adjustable A-Type configuration is particularly useful when the lighting system requires fine adjustment of output voltage or current during installation and commissioning. Always verify the LED load's required voltage, current, wiring, and driver operating mode before installation.\u003c\/p\u003e\n\u003ch6\u003eTechnical Specifications\u003c\/h6\u003e\n\u003ctable style=\"width: 100%;

The voltage can be adjusted within the specified 13.5-17V range, while the current can be adjusted from approximately 1.6A to 2.67A.
