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-150-54A for a 54V industrial control or automation load?

Yes, this model is a constant-voltage 54V power supply rated for 151.2W and 2.8A. It is suited to equipment that specifically requires a 54V DC source within that power and current range.

Is the HEP-150-54A a good fit for embedded or edge equipment in harsh industrial environments?

It is specified for 10G vibration (20-500Hz along the X, Y and Z axes) and carries an IP65 rating. The operating range of -55°C to +70°C (refer to the derating curve) also makes it suitable for embedded or control equipment exposed to very low or very high ambient temperatures.

Can this power supply be used for outdoor 54V equipment cabinets or enclosures?

It can be used in outdoor applications where IP65 water resistance is appropriate. IP65 supports resistance to water ingress and dust, and the unit is built for -55°C to +70°C operation.

Would the HEP-150-54A work for a 54V automation device that runs continuously?

It provides a stable 54V constant-voltage output (±1.0% voltage tolerance) up to 151.2W and 2.8A. Its typical efficiency of 94% keeps heat losses low, which helps in enclosed industrial equipment.

How does the HEP-150-54A compare with other 54V models in the HEP series?

On the HEP-150 sheet, the only other 54V model is the HEP-150-54, which has the same 151.2W at 2.8A rating. The HEP-150-54A is IP65, while the HEP-150-54 (blank type) is IP68. The other HEP-150 voltages are 12V, 15V, 24V, 36V and 48V.
