Test conditions and notes10
  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. 5. A type only.
  6. 6. Safety and EMC design refer to BS EN/EN60598-1, CNS15233, GB7000.1, FCC part18.
  7. 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.
  8. 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)
  9. 9. The water protection level test for the IP68 rating is performed 1000mm below the surface of the water for 1 month.
  10. 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-150-48 for 48V industrial networking or communications equipment?

Yes, if the equipment is specified for 48V DC constant-voltage input. This model supplies up to 3.2A and 153.6W, so the total load must stay within those limits.

Is this a good power supply for 48V automation controllers or field devices?

It is suitable for 48V DC automation hardware that operates from constant voltage rather than constant current. The available output is 48V at up to 3.2A, with a maximum power of 153.6W.

Can the HEP-150-48 power a 48V embedded or IT device in a rugged environment?

It can, provided the device requires 48V constant voltage and draws no more than 153.6W. The IP68 rating, 10G vibration capability, and -55°C to +70°C operating range support use in harsh industrial locations.

Is the HEP-150-48 suitable for exposed outdoor conditions?

This version carries an IP68 rating, which makes it appropriate for more demanding indoor or outdoor environments than an IP65 model. The operating temperature range of -55°C to +70°C also supports use across very wide ambient conditions.

How does the HEP-150-48 compare with other HEP-150 models?

Within the HEP-150 series, 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 shares its electrical rating with HEP-150-48A.
