Test conditions and notes9
  1. 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature.
  2. 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor.
  3. 3. Tolerance : includes set up tolerance, line regulation and load regulation.
  4. 4. Derating may be needed under low input voltages. Please check the static characteristics for more details.
  5. 6. Safety and EMC design refer to BS EN/EN60598-1, CNS15233, GB7000.1, FCC part18.
  6. 7. Length of set up time is measured at cold first start. Turning ON/OFF the power supply may lead to increase of the set up time.
  7. 8. The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-qualify EMC Directive on the complete installation again. (as available on https://www.meanwell.com//Upload/PDF/EMI_statement_en.pdf)
  8. 9. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.
  9. 10. The ambient temperature derating of 3.5℃/1000m with fanless models and of 5℃/1000m with fan models for operating altitude higher than 2000m(6500ft).

FAQ

Can I use the HEP-150-54 for 54V industrial communications or control equipment?

Yes, if the equipment is designed for 54V DC constant-voltage operation. This power supply provides up to 2.8A and 151.2W, so the connected load needs to stay within those limits.

Is the HEP-150-54 suitable for 54V embedded or automation systems in harsh locations?

It can be used for 54V constant-voltage systems that do not exceed 151.2W. The IP68 rating, 10G vibration tolerance, and operating range of -55°C to +70°C make it suitable for demanding industrial environments.

Can this model power 54V DC equipment used in industrial or IT cabinets?

It is appropriate for cabinet-mounted 54V DC equipment when the total draw remains at or below 2.8A. Because it is a constant-voltage supply, the load should explicitly require 54V DC constant-voltage input.

Is the HEP-150-54 rated for outdoor use or harsh weather exposure?

This version is rated IP68, so it is intended for more severe environmental exposure than an IP65 variant. It also operates from -55°C to +70°C, which supports use in very cold or hot conditions.

How does the HEP-150-54 compare with the rest of the HEP-150 family?

Across the HEP-150 line, HEP-150-12 and HEP-150-12A are 150W at 12V and 12.5A, HEP-150-15 and HEP-150-15A are 150W at 15V and 10A, HEP-150-24 and HEP-150-24A are 151.2W at 24V and 6.3A, HEP-150-36 and HEP-150-36A are 151.2W at 36V and 4.2A, HEP-150-48 and HEP-150-48A are 153.6W at 48V and 3.2A, and HEP-150-54 and HEP-150-54A are 151.2W at 54V and 2.8A. This SKU has the same 54V, 2.8A, and 151.2W electrical rating as HEP-150-54A.
