Mean Well HLG-240H-42 Power Supply 240W 42V

Yes. The HLG-240H-42 provides 240W at 42V and 5.72A in constant-current mode, which suits many 42V LED grow light boards and quantum board arrays. The CC voltage range of 21-42V ensures stable current delivery as LED forward voltage shifts with temperature during operation.

Yes. With an IP67 waterproof rating and -40°C to +90°C operating temperature range, it handles fully exposed outdoor installations. At 240W and 42V, it can power LED flood or area lights used on building exteriors, parking structures, or sports courts.

Yes. The 240W capacity at 42V with 5.72A output can power substantial arrays of 42V LED modules for channel letters, cabinet signs, or pylons. The IP67 waterproof rating ensures reliable operation in rain-exposed sign enclosures year-round.

Yes. The base HLG-240H-42 (no letter suffix) has a fixed 42V output with no built-in potentiometer adjustment or dimming input. If you need output trimming, choose the -42A. For dimming via 1-10V/PWM, choose the -42B or -42AB variant.

Divide 240W by your strip's power consumption per meter. For example, a 42V strip rated at 16W/m would allow 15 meters (240W / 16W per meter = 15m). Always check your specific strip's rated power per meter and keep the total load at or below 240W.

Yes. The IP67 rating means it is dust-tight and protected against temporary submersion up to 1 meter. It can be mounted outdoors in fully exposed conditions, including rain, snow, and high-humidity coastal areas. The aluminium casing resists corrosion and provides effective heat dissipation.
