FAQ

Can I use the ELG-150-36AB to power a 36V LED strip installation in a covered outdoor area?

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.

How many meters of 36V LED strip can the ELG-150-36AB power?

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 load to about 80% for a safe continuous load, giving approximately 12 m or 8.3 m respectively in those examples.

Is the ELG-150-36AB suitable for outdoor LED channel letter signage?

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 case temperature (Tcase) range accommodates both cold-climate and heat-exposed cabinet installations, with derating at high ambient temperatures.

Can I dim the ELG-150-36AB and also manually adjust its output voltage?

Yes. The 'A' function is a built-in potentiometer for output adjustment and the 'B' function is 3-in-1 dimming (0–10V, 10V PWM or resistance). The ELG-150-36AB includes both, so you can fine-tune the output voltage (32.4–39.6V) and current (2.1–4.17A) using the onboard potentiometer and also dim the driver via a 0–10V control signal.

Can this driver power 36V LED strips for architectural cove lighting indoors?

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.

Is the ELG-150-36AB a good choice for retail display case lighting using 36V strips?

Yes. Its compact 219 × 63 × 35.5 mm 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.

How does the ELG-150-36AB compare to the ELG-150-36 and ELG-150-36B in terms of control options?

All three share the same 150.1W, 36V, 4.17A output; the ELG-150-36 and 36B are IP67 and the 36AB is IP65. The ELG-150-36 has no dimming or adjustment. The ELG-150-36B adds 3-in-1 dimming (0–10V / PWM / resistance) without a potentiometer. The ELG-150-36AB adds both the adjustment potentiometer and the 3-in-1 dimming input, making it the most flexible variant for dimming-capable installations.
