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 the HEP-150-24A be used for 24V industrial control panels?

Yes, if the panel or subsystem requires constant voltage 24V and stays within 151.2W and 6.3A. The 90-264VAC input (277VAC operational), IP65 rating, and -55°C to +70°C operating range suit industrial control applications.

Is this a good choice for 24V field devices or automation hardware in rough environments?

It can be used for 24V field or automation hardware that needs up to 6.3A from a constant voltage supply. The 10G vibration resistance and IP65 water-resistant design support use in tougher operating conditions.

Can I use the HEP-150-24A for 24V LED lighting or signage systems?

Yes, for constant voltage 24V loads that do not exceed 151.2W or 6.3A. Its IP65-rated construction makes it more suitable for dust-prone or damp areas than a ventilated indoor power supply.

Is the HEP-150-24A suitable for outdoor service?

It is suitable for many outdoor and industrial locations because it is IP65 water-resistant and rated for -55°C to +70°C operation. IP65 is intended for exposure to dust and water, but it is not the same protection level as IP68.

How does the HEP-150-24A compare with the rest of the 150W HEP family?

HEP-150-24A and HEP-150-24 are the 24V members of the family, both rated at 151.2W and 6.3A. The other 150-size options are HEP-150-12 and HEP-150-12A at 150W, 12V, 12.5A; HEP-150-15 and HEP-150-15A at 150W, 15V, 10A; HEP-150-36 and HEP-150-36A at 151.2W, 36V, 4.2A; HEP-150-48 and HEP-150-48A at 153.6W, 48V, 3.2A; and HEP-150-54 and HEP-150-54A at 151.2W, 54V, 2.8A.
