Mean Well ELG-150-36AB Power Supply 150W 36V - Adjustable and Dimmable

Yes. The ELG-150-36AB is rated IP65, meaning it is protected against low-pressure water jets from any direction. This makes it suitable for covered outdoor or semi-exposed locations such as canopies, soffits, or sheltered signage cabinets where the driver will not be directly rained on.

The ELG-150-36AB delivers 150.1W at 36V. To estimate strip length, divide 150W by your strip's rated power per meter. For example, a 10 W/m strip yields roughly 15 meters maximum; a 14.4 W/m strip yields roughly 10.4 meters. Always check your specific strip's rated power per meter and derate by ~80% for a safe continuous load, giving approximately 12 m or 8.3 m respectively in those examples.

Yes. The 36V output and 150.1W capacity make it a strong match for medium to large LED channel letter signs. Its IP65 rating provides dust-tight protection and resistance to water spray, covering most signage enclosure environments. The -40°C to +90°C operating temperature range accommodates both cold-climate and heat-exposed cabinet installations.

Yes. The 'A' suffix indicates an analog voltage/resistance dimming input (0–10V or 10V PWM or resistance), and the 'B' suffix indicates a built-in potentiometer for output voltage trimming. The ELG-150-36AB includes both, so you can fine-tune the output within the 18–36V constant-current range using the onboard trim pot and also dim the driver via a 0–10V control signal.

Yes. The ELG-150-36AB works well for indoor architectural cove or linear lighting runs using 36V strip. The constant-current operation with a 18–36V compliance range accommodates varying strip lengths within one run, and the 0–10V dimming allows smooth integration with building automation or wall dimmers.

Yes. Its compact 219 × 63 × 35.5 mm metal case fits in most display case back-panels or under-shelf enclosures. At 150.1W, it can power multiple short runs of 36V strip simultaneously, and the 0–10V dimming allows brightness adjustment without a separate dimmer module.

All three share the same 150.1W, 36V, 4.17A output and IP65/IP67 housing. The ELG-150-36 has no dimming or adjustment. The ELG-150-36B adds only a built-in output-voltage trimming potentiometer. The ELG-150-36AB adds both the potentiometer (B) and a 0–10V / PWM / resistance dimming input (A), making it the most flexible variant for dimming-capable installations.
