Frequently Asked Questions
Can I use the HLG-120H-48 to power 48V LED strip lighting outdoors?
Yes. The HLG-120H-48 outputs 48V at up to 2.5A (120W) and carries an IP67 waterproof rating, making it well suited for outdoor 48V LED strip installations exposed to rain, snow, or high humidity. Its aluminium casing and -40°C to +80°C operating range handle harsh weather conditions.
Is the HLG-120H-48 suitable for powering 48V LED signage systems?
Yes. With 120W of output at 48V, it can drive 48V LED sign modules used in channel letters or light boxes. The wide 90-305VAC input accommodates varying mains voltages worldwide, and IP67 protection allows direct outdoor mounting near the sign without a separate enclosure.
Can I run 48V LED high-bay or warehouse lighting from the HLG-120H-48?
Yes, provided the total LED load stays within 120W. The HLG-120H-48 operates in constant-current mode with a CC voltage range of 24-48V, so it can accommodate fixtures that draw at different voltage levels within that range. Its IP67 rating also suits dusty or damp industrial environments.
How many meters of 48V LED strip can the HLG-120H-48 power?
That depends on the strip's rated power per meter. The HLG-120H-48 supplies up to 120W at 48V. For example, if your strip draws 10W/m, you could run up to 12 meters (120W / 10W per meter = 12m). Always check your strip's rated power per meter and keep total load at or below 120W.
Can the HLG-120H-48 be mounted outdoors without an additional weatherproof enclosure?
Yes. Its IP67 waterproof rating means the unit is protected against temporary submersion up to 1 meter of water. It can be mounted on exterior walls, poles, or in open areas exposed to rain without needing a secondary enclosure.
What are the differences between the HLG-120H-48, 48A, 48AB, and 48B models?
All four share the same 120W / 48V / 2.5A core specs. The base HLG-120H-48 has no output adjustment and is IP67 waterproof. The -48A adds output voltage/current adjustment via built-in potentiometer and is IP65. The -48AB adds both adjustment and 1-10V/PWM dimming input (IP65). The -48B adds dimming input only and retains IP67.
